When HDMI first appeared more than 20 years ago, it set a new standard for high-definition home entertainment. Today, HDMI — which stands for “

” — remains among the most popular digital interfaces used to transmit high-definition video and audio signals over a single cable.

HDMI cables connect the output from any number of HD sources (streaming devices, soundbars, gaming consoles, etc.) to the input of an HD display, such as a high-definition TV or projector. Since you probably use at least one of these devices on a daily basis, chances are that you’ve already plugged in an HDMI cable without even knowing it.

In this guide, we’ll give you a brief introduction to HDMI. We’ll also walk you through the basics of HDMI ARC and HDMI eARC, two audio-focused technologies that simplify your life by reducing the cables needed to connect your TV to a compatible 

To understand what HDMI is and what it does, it helps to simply break down the acronym:

The best new TVs support stunning crisp image and audio quality. But higher quality means a huge amount of data. Not every cable or connection is capable of transferring all this data from an input source to your TV at the speed or bandwidth required for optimum performance. HDMI was created to solve this problem, and newer versions keep ratcheting up the bandwidth to keep pace with ever-increasing levels of video and audio quality.

When we say “multimedia,” all we mean is that HDMI can support more than one type of media. HDMI supports both uncompressed video and multi-channel audio; that’s why we call it a multimedia interface.

An interface is essentially just a connection between two devices. It’s the place where those two devices communicate and share data back and forth with each other. In this case, HDMI acts as an interface between an input device (the source of your entertainment) and an output device (the thing that plays or displays your entertainment).

Say you have a source of audio and video data that you want to connect to your TV. This source could be a streaming device such as a Roku or Apple TV, a modern gaming console such as a Playstation or Xbox, or a Blu-ray player.

 (in other words, a physical connection) that allows you to transfer all this 

 (i.e. audio and video) data. But not just any interface will do. You need one that can transfer a huge amount of data at an incredibly fast rate, in order to achieve the 

 quality that has become standard among modern TVs, projectors, and other entertainment devices.

You may notice that we italicized some words in the above description. When you combine these words together, you get 

, or HDMI. This interface is widely used to transmit digital audio and video signals across devices, and it eliminates the need for multiple cables by consolidating different signals into a single connection.

HDMI cables can be used to transmit uncompressed digital audio and video signals between compatible devices.

 14-millimeter HDMI cable (Type A) has 19 pins and two “male” connector ends, both of which plug into “female” sockets on the devices it connects. Standard HDMI cables come in varying lengths, but as a general rule, the shorter the cable, the faster the data is transferred. Once you get past 10 meters or so, you may start to see some noticeable signal degradation.

Newer versions of HDMI cables support higher data-transfer rates. These cables look like the Standard cable but are labeled 

. Both are an improvement over Standard, but if you want the best possible experience with the latest HDMI 2.1 components, you may want to stick to the Ultra High Speed cable.

The good news is that these newer cables are all backward-compatible, meaning you can use them with earlier-version devices that were released before the upgrade in cable technology. The bad news is that a cable alone will not upgrade the quality of those old devices.

: Other types of HDMI connectors — Type B, C, D, and E — also exist for different use cases, e.g. smartphones, cameras, and vehicle entertainment systems. We’re focusing on Type A here, as it’s the standard connector for home-entertainment devices.

The ARC in HDMI ARC stands for “Audio Return Channel.” If you use your TV with a soundbar or audio receiver, this feature helps you cut down on cables.

In a non-ARC setup, you would need a total of three cables:

An HDMI cable to connect your source device to the audio system

Another HDMI cable to connect your audio system to your TV

An optical/audio cable to connect your TV 

With HDMI ARC, you can eliminate this third cable. This is because the HDMI cable that connects your audio system to your TV can also send the TV audio 

 into your audio system. Instead of having two one-way roads, you’re essentially combining them into a single two-lane data highway.

ARC is not necessary if you only plan to use your TV’s speakers. But if you want to use an external speaker, it not only eliminates the need for an extra cable, but also improves the sound quality of the signal by allowing the same signal to travel in both directions (to and from the speaker).

HDMI ARC is compatible with HDMI 1.4 cables and all later versions. If you’re planning to connect a Blu-ray player or any other content source with video resolutions of 1080p or higher, you should likely spring for at least a High Speed HDMI cable. Before rushing out to buy a cable separately, though, note that most soundbars already come with an HDMI ARC cable in the box.

Just note that the devices you’re connecting also have to be HDMI ARC-enabled. You should see “ARC” clearly marked on the HDMI port of your TV or source device if it’s compatible.

HDMI eARC stands for HDMI “Enhanced Audio Return Channel.”

The eARC standard was introduced in the latest version of HDMI (HDMI 2.1). It works in much the same way as HDMI ARC, though it boasts even higher audio bandwidth.

This extra bandwidth allows eARC to support higher-quality surround-sound technologies. For example, though most 

you’ll need HDMI eARC to play lossless Dolby Atmos audio

You typically don’t have to do anything special to enable HDMI eARC; simply connect the HDMI cable as you normally would. If your TV or projector supports eARC, you may see an “eARC/ARC” or similar label on its HDMI port. If you don’t see this label, check the user guide to confirm if eARC is supported.

You don’t necessarily need a special cable for HDMI eARC, though a High-Speed HDMI cable or an Ultra High Speed HDMI cable is probably a good bet. The latter option is sure to work, as the Ultra High Speed specifications support all HDMI 2.1 features.

As is the case with all newer HDMI cables, the Ultra High Speed cable is backwards-compatible with devices that don’t support HDMI 2.1.

If you’re using external speakers with your 

 and you’re concerned with maximizing the quality of your audio output, HDMI eARC is the way to go. Just note that all of the components in your mix — your TV as well as your soundbar or audio system — must be eARC-compatible to ensure optimal bandwidth. Otherwise, your bandwidth may be limited by the weakest link in your system, i.e. the device that’s only compatible with ARC.

Acoustic instrumental more your brand’s tempo? Done. Sonos Pro includes access to ad-free commercially licensed music for every type of business.

The Beginner’s Guide to Commercially Licensed Music

When managing your business, every element plays an important role in shaping the customer experience. One often overlooked but impactful aspect is the ability for music to influence your customer’s purchasing behaviors. However, while it may be tempting to play a popular tune from your personal playlist, streaming  music in a commercial space is not the same as enjoying music at home or on the go.

A subscription to a consumer music service such as Apple Music or Spotify provides a license to stream music for personal use, but does not provide a license to stream music for commercial use.  This means that the service cannot be used on a sales floor or restaurant dining room while the business is open. You’ll need to check  the terms of your consumer music service before playing any popular hits in your business.

, it means that the rights to use and distribute the musical work have been granted by the appropriate copyright owners or rights holders. Licensing is a crucial part of the music industry, ensuring that artists, songwriters, and creators are compensated for their work and that users have the legal right to use the music in specific ways.

For the case of restaurants, cafes, and retail stores, the law considers your brick-and-mortar business to be a public space, and music played in that space requires a specific license for commercial use. These licenses come in different types, each giving specific rights and limitations on how music can be used. One license that is required for commercial spaces is a 

, which is handled by Performance Rights Organizations (PROs), such as ASCAP, BMI, and SESAC (among others) in the United States.

Commercially Licensed Music: How to Select Sound for your Business

Imagine walking through your home, seamlessly enjoying your favorite music or catching every bit of dialogue from a movie, no matter which room you're in. The idea of continuous music or sound following you throughout your house might seem like a luxury, but creating this sound experience is easier than ever with a multiroom audio setup. In this guide, we’re explaining how a multiroom audio system works and offering a few tips for creating one.

Multiroom audio is a system that lets you play the same music, podcasts, and other types of audio in multiple rooms of your home at the same time. That means you can go from one space to the next without the music fading away into the background.

For example, you can listen to your favorite playlist while doing chores around the house, and as you walk from room to room, the music will follow. Or maybe you're watching a movie and want to grab a bowl of popcorn from the kitchen. Instead of hitting pause, you can sync the audio from your TV to your kitchen speaker and step away without missing a word.

At its core, multiroom audio works by linking various speakers across different rooms to play synchronized audio. This can be achieved through wireless or wired connections, depending on your setup and preferences.

A wireless sound system, like Sonos, is one of the easiest ways to get multiroom audio. Once you place your speakers in their desired locations and plug them into power, you can link them together over your WiFi network. A wired connection, on the other hand, requires some drilling and physically connecting your speakers to an amplifier, either through the walls or ceiling. This typically requires professional installation, but it’s great if you want your speakers to blend discreetly into your space.

Once your speakers are setup, most systems come with user-friendly controllers or apps that allow you to manage playback in different rooms using your smartphone, tablet, or computer. If you have a Sonos system, the Sonos app allows you to simply group rooms and speakers together. You can even create custom groups or zones that are frequently synced together. For example, you can create a custom group called “Downstairs” to enable playback across all the speakers on the same floor of your home.

Note that you can still enjoy the benefits of wireless control even if you have a wired system.

What Do You Need to Set Up Multiroom Audio?

For a multiroom audio setup, you need a speaker in every room where you want sound. These speakers can range from bookshelf speakers to sleek soundbars or discreet in-wall or in-ceiling speakers, depending on your preferences and room aesthetics.

Once you’ve decided on the type of speakers you’d like, they need to be connected to each other. As previously discussed, wireless connections — especially via WiFi — are most popular for their convenience and flexibility. However, certain scenarios may necessitate wired connections — like playing audio from physical media (such as CDs and vinyl) or using passive speakers like in-ceiling speakers, which will require a separate amplifier for power, such as 

. However, for most users, WiFi is the recommended and preferred option due to its ease of use.

Controlling a multiroom audio system typically involves using a dedicated app or controller. These allow you to effortlessly manage and customize audio playback across different rooms. For instance, if you have a Sonos system, the Sonos app allows you to seamlessly group and ungroup different speakers or “rooms.”

Depending on your setup, you might require additional equipment such as amplifiers or receivers, especially if you're integrating a traditional stereo setup or architectural speakers into your multiroom audio system. This typically requires you to have an AV closet, or dedicated space in your home to house all of the equipment, which could require an additional build-out if not readily available.

This approach involves bringing individual speakers, like 

, into each room where you’d like to listen. These speakers are then connected over WiFi, providing an easy-to-set-up and adaptable system that you can expand in the future.

Another setup involves using built-in speakers like in-ceiling or in-wall options for a more integrated look. However, due to the complexity involved in installation, it's recommended to enlist the expertise of a

How to Create a Multiroom Audio Setup in Your Home

Have you ever wanted to transport yourself into the heart of a concert hall or immerse yourself in the sounds of nature without leaving the comfort of home? With the emergence of spatial audio, this easily becomes a reality. In this beginner's guide, we’re exploring the world of spatial audio, how it works, and how you can listen yourself.

Spatial audio is an innovative technology that creates a three-dimensional listening experience, making it seem as if sound is coming from various directions and distances. Unlike traditional stereo sound, where audio is delivered through two channels (left and right), spatial audio adds an extra dimension by incorporating height. This technology allows you to perceive sound as though it's coming from specific locations around you, mimicking how sound travels in real life.

, spatial audio uses sophisticated algorithms, advanced processing techniques, and specialized hardware to recreate lifelike soundscapes. Using object-based sound technology, such as 

, sound objects (including vocals, instruments, or effects) are strategically assigned to specific locations in a 3D space rather than a fixed channel.

Say you’re listening to spatial audio on a single speaker, like 

. To produce sound that feels like it’s coming from above, upward-firing drivers in the speaker bounce sound off the walls and ceiling, which get reflected to a specific location in the room. Because audio isn’t being projected in one direction, as is the case with 

, your content feels like it’s hitting you from every direction.

A standout quality of Dolby Atmos is its ability to adapt to various hardware and playback setups. Whether listening on 

, Dolby Atmos optimizes the sound to your environment for a more realistic listening experience.

Spatial audio brings you closer to the creator's original intent, allowing you to hear your content the way it was meant to be heard. When listening to music, you'll feel as if you're in the recording studio, surrounded by every instrument and nuanced detail. When watching a movie, the explosions will reverberate around you, the dialogue will appear to come from specific corners of the room, and ambient sounds will transport you into the center of the scene — it's like having a private cinema right in your living room. Spatial audio enriches your emotional connection to your content by making it more engaging and lifelike.

How can I listen to spatial audio at home?

To experience your music and movies in spatial audio from the comfort of home, you’ll need two things: a Dolby-Atmos supported streaming service and a compatible device. Below are a few types of devices you can use to play Dolby Atmos content:

One of the most popular ways to experience spatial audio is with a pair of headphones.

If you want to experience spatial audio out loud instead of using headphones, some 

 — can fill a large space with immersive Dolby Atmos content. No matter where you are in the room, it will feel like the music is playing all around you.

Similar to a smart speaker, some high-end 

, can support spatial audio for movies and TV shows for a theater-like experience. These systems often include upward-firing 

 to bounce sound off the ceiling to create an all-encompassing effect.

If you want to put yourself inside your games, certain consoles and PCs with compatible sound cards can deliver a truly lifelike experience when playing content mixed in Dolby Atmos.

Some VR headsets provide spatial audio as part of their virtual experiences. When pairing spatial audio with VR content, these headsets can offer an incredibly immersive audio-visual experience.

Spatial audio represents a groundbreaking leap in the way we enjoy our favorite movies, music, and games. Its ability to create immersive, lifelike audio environments opens up new dimensions of entertainment where sound isn’t just heard but felt.

The Beginner’s Guide to Spatial Audio

Every listener wants to make sure they’re getting the best sound quality. That often comes down to choosing between mono sound and stereo sound. It’s easy to assume that stereo sound is always better, but there are many reasons you might want to choose mono.

In this post, we explain the differences between mono and stereo sound and explore the advantages of each. We also provide some helpful tips on choosing the right speakers for your space. Now, let’s dive in.

Mono is short for monophonic, which means “one sound.” (In Greek, monos means “one” and phone means “sound.”)

When a speaker is described as having mono sound, that means it has a single audio channel for playback. So, when you listen to music, all the elements of a song — such as the guitars, drums, and vocals — combine and play through the same single channel at the same volume.

Because mono sound compresses audio elements together, it can sound flatter and less detailed, particularly when you listen to music, which is typically recorded and mixed in stereo. Low frequencies (

Mono sound also has a narrow soundstage. In other words, it sounds as if it comes from a single point and direction. The further you move away from the center point of that single audio channel, the less detail you’ll hear.

Today, mono sound remains most commonly used for voice recordings because of its advantages in reducing background noise and capturing a voice in the clearest, most natural way possible. You’re most likely to experience mono sound when you’re listening to a podcast, AM radio, or someone on the other end of a phone call or video call.

Whereas mono sound is limited to just one audio channel, stereo sound uses two audio channels: the left and the right. This creates a more realistic and immersive listening experience. (In Greek, stereos means “solid” or “three dimensional.”)

When you listen to music in stereo, different elements of a song are assigned to either channel. This creates a wider, more dynamic soundstage that mimics the experience of listening at a live concert. For example, it may sound like a bass guitar is to your right, violins are on the left, and the vocals are front and center, where the lead singer would be.

By separating instruments and vocals into different channels, each element has more “space to shine” so it sounds clearer. The impression of depth and space also enhances the emotional power of sound, which is why stereo is the go-to recording format for music, movies, TV, and video games.

The choice between mono and stereo sound depends on the listening situation.

Generally speaking, stereo sound is better for music, 

, and video games because it is more immersive and because these types of audio files are made specifically for stereo listening. Stereo sound, however, is not categorically superior to mono sound.

As previously mentioned, mono sound is preferable when the focus is on clarity of a single voice or instrument. So, if you primarily listen to podcasts, mono sound is great.

Mono sound is also better for background music, particularly when you have multiple speakers (like 

) covering a large area. In this scenario, mono sound ensures that everyone hears the same audio at the same volume for a more balanced and consistent listening experience as they move through the space.

As a single source of audio, mono sound is also easier to process for listeners with hearing impairments.

 is capable of playing mono sound. When a mono speaker plays a stereo recording, it combines both the left and right channel into one. This reduces the stereo separation of the track so the sound appears “in the middle.”

, are capable of stereo playback because they feature separate 

 for the left and right channels. When a stereo speaker plays a mono recording, the left and right channels duplicate the same audio signal. This is known as dual mono.

Speakers with an identical acoustic architecture and sound profile can be paired in the same room for stereo sound. So, you can achieve a stereo listening experience with two mono speakers.

When you pair two stereo speakers, one becomes a dedicated left channel and the other a dedicated right channel for a bigger, richer soundstage overall. If you play a mono recording, each speaker will duplicate it and fill the room more evenly with dual mono sound.

Stereo sound features two channels — the left and right — that recreate the soundstage of a live performance. While it offers depth and directionality, stereo sound is limited to a single plane.

Surround sound features at least four channels (usually five) for a more immersive listening experience. Surround sound also recreates the soundstage of a live performance, but it adds a sense of three-dimensionality with rear speakers that produce sounds to the sides and behind you.

Surround sound is ideal for home theater experiences, as it brings movies, shows, and video games to life in a more realistic way. For movies — which are most often mixed for this format — a surround sound system can be worth the investment if you want to feel more immersed in the story.

When choosing speakers for your home, it’s important to consider the desired listening experience, the size of your room(s), and your budget.

Ask yourself if you need speakers for a specific purpose. For example, are you just interested in listening to podcasts, or would you prefer more immersive sound for music? Do you want to create a home theater system? Is portability and the option to listen outdoors a factor?

If you’re trying to cover a large space, you’re going to want either fewer, more powerful speakers, or a greater quantity of less powerful speakers. (When determining how powerful a speaker is, it’s helpful to look at its size and the number of drivers.) For a smaller room, look for a more compact speaker that won’t overwhelm the space.

, the flexibility to mix and match speakers is key — as is the ability to easily control your whole system.

From an affordable mono speaker you can use everywhere to a world-class stereo system and everything in between — Sonos makes it easy to fill your home with incredible sound. You can also choose one speaker that fits your budget now, then get a second later to create a stereo pair and upgrade your listening experience.

Mono vs. Stereo Sound: What's the Difference?

High-fidelity audio — or hi-fi, for short — is audio that’s reproduced from the original recording with as high a degree of exactness as possible. Short of staging a live show or concert in your living room, a hi-fi audio setup should deliver the best sonic quality you can experience at home.

But the term “hi-fi” is subjective. It depends as much on personal taste as it does on technical factors. Some might consider the quality of a standard CD to be hi-fi, as it hovers near the crispest sound the human ear can perceive. Others thirst for even purer levels of playback, unwilling to forgo the subtle pleasure of picking out a single voice from a choir, or hearing a finger gently settle on a guitar string.

In this guide, we’ll define hi-fi audio in more depth, focusing on everything from sound waves to the components involved in a typical home setup. Just as important, we’ll help you define what hi-fi means 

. Because what’s the point of hi-fi audio if your ears don’t enjoy it?

Hi-fi audio is audio that reproduces the sound of an original recording with minimal levels of distortion and a full, accurate range of audible frequencies. If the human ear is unable to discern any difference between an in-person performance and an audio reproduction of that performance, the latter would generally qualify as hi-fi audio.

You might assume that the evolution of audio technology in the last century has been one long, uninterrupted march toward hi-fi perfection. But you’d be wrong.

Port placed on top of books lying on a bookshelf

The term “hi-fi” was introduced in the 1950s to describe newer at-home audio systems that often involved multiple components. Such setups achieved levels of sonic accuracy that far surpassed the phonographs and AM radio frequencies of yore.

The development of stereophonic equipment, which brings a greater sense of width and spaciousness to recorded sounds, marked an especially important breakthrough in hi-fi audio. Another milestone came in the 1980s with the explosion of CDs, a new digital format that reduced noise without compromising much in terms of quality.

 in the 2000s with the advent of streaming, which compresses audio files so that they take up less storage space. This compression often comes at the expense of fidelity. Newer streaming formats have shown better results, but before we get too far ahead of ourselves in talking specs, let’s establish what we’re actually 

 when we listen to hi-fi audio in the first place.

If you were to say that hi-fi audio is audio that “sounds good,” well, you’d technically be right. But what elements of a recording contribute to its sounding good?

There are a lot of nooks and crannies we could dive into, but here are five major factors to pay attention to when evaluating the fidelity of a digital audio recording:
