Soundbar Hi-Res Audio Support: What to Know

What Hi-Res Audio Means on a Soundbar Listing

When a soundbar listing includes the term "hi-res audio" or "Hi-Res Audio Certified," it indicates that the soundbar is designed to handle audio files with a higher resolution than standard CD-quality audio. CD-quality audio is typically 44.1kHz sampling rate and 16-bit depth. Hi-res audio generally refers to formats that exceed those numbers, such as 96kHz/24-bit or 192kHz/24-bit.

The certification is often awarded by organizations like the Japan Audio Society, though the listing itself may not name the certifying body. For example, Polk Audio describes some of its speakers and soundbars as "Hi-Res Audio Certified" on its product pages, meaning the product meets the technical requirements to reproduce hi-res audio content.

On a soundbar, hi-res audio support is a feature that appears most often on premium models. It tells you that the soundbar's internal components, such as the digital-to-analog converter (DAC) and amplifier, are capable of processing high-resolution signals. However, the listing alone does not guarantee how the soundbar will perform with that content; it only states the capability.

How Hi-Res Audio Gets to Your Soundbar

To take advantage of hi-res audio, the soundbar must receive a hi-res signal from the source device. The most reliable connection for this is HDMI eARC. The HDMI specification states that eARC "supports the most advanced audio formats and highest audio quality," which includes hi-res multichannel formats like Dolby TrueHD and DTS-HD Master Audio. If your TV and soundbar both support HDMI eARC, you can pass hi-res audio from a Blu-ray player or streaming device through the TV to the soundbar.

Optical (Toslink) connections are limited to compressed 5.1 audio at 48kHz/24-bit, so they cannot carry full hi-res audio. Bluetooth can stream audio wirelessly, but the maximum resolution depends on the codec. The Bluetooth Classic radio is used for audio streaming, but the standard itself does not guarantee hi-res support. Some soundbars may support codecs like LDAC or aptX HD, but those are not always listed. For the highest fidelity, a wired HDMI eARC connection is recommended. For more on connection types, see soundbar connectivity options.

If you plan to play hi-res music files from a phone or computer, check whether the soundbar supports USB audio input or Wi-Fi streaming with hi-res compatibility. The listing may mention "USB Audio" or "Wi-Fi streaming" but not always specify the supported sample rates. A soundbar with HDMI eARC is the best choice for lossless audio.

Does Hi-Res Audio Matter for TV and Movies?

For most TV viewing, the audio source is not hi-res. Broadcast TV, streaming services like Netflix and Hulu, and cable boxes typically use compressed audio formats such as Dolby Digital or Dolby Digital Plus, which have lower bitrates and sample rates than hi-res. Even when a streaming service offers Dolby Atmos, the audio is usually delivered in a lossy format that does not meet hi-res standards.

The exception is physical media. Blu-ray discs and Ultra HD Blu-ray discs often include lossless audio tracks like Dolby TrueHD and DTS-HD Master Audio, which are hi-res. If you have a Blu-ray player and a soundbar with HDMI eARC, the soundbar can receive those lossless tracks. For movie enthusiasts with a disc collection, hi-res audio support can be a relevant feature. For immersive formats, see best Dolby Atmos soundbars.

For the majority of TV and streaming users, hi-res audio support is not a deciding factor. The soundbar's channel layout, subwoofer, and room placement will have a much larger impact on your listening experience.

Hi-Res Audio for Music Listening

If you listen to music through your soundbar, hi-res audio support becomes more relevant. Some music streaming services offer hi-res tracks at 96kHz/24-bit or higher. Some services also offer Dolby Atmos Music, which can be hi-res. A soundbar that supports hi-res audio can play these tracks at their full resolution, provided the connection (HDMI eARC or Wi-Fi) can carry the signal.

However, many soundbars are optimized for TV and movie sound rather than critical music listening. If music is a priority, you may want to look for a soundbar that explicitly states hi-res audio certification and has a dedicated music mode. The listing may also mention support for specific file formats like FLAC, ALAC, or WAV up to a certain sample rate. Compare soundbar music vs movies to decide what fits your needs.

For casual music listening from a phone via Bluetooth, hi-res support is less critical because Bluetooth compression may reduce the audio quality regardless of the soundbar's capabilities.

How to Identify Hi-Res Audio Support on a Listing

Soundbar listings may use several phrases to indicate hi-res audio support. Common terms include "Hi-Res Audio Certified," "Hi-Res Audio," "24-bit/96kHz support," or "high-resolution audio." Not all listings will include these terms, especially for budget models. If the feature is important to you, check the maker's official product page for detailed specifications.

For example, Polk Audio's Monitor XT series is described as "Hi-Res Audio Certified" on the Polk website. Similarly, some Denon and Sony soundbars list support for 24-bit/96kHz audio. The listing on the store page may not include this detail, so it is worth visiting the manufacturer's site to confirm.

Also look for related features that enable hi-res playback, such as HDMI eARC, USB audio input, or Wi-Fi streaming with high-resolution support. A soundbar that lacks HDMI eARC may still play hi-res audio through a direct USB connection, but that limits your source options. For premium options with these features, see best premium soundbars.

Should You Care About Hi-Res Audio?

Hi-res audio support is a specification that matters only if your source material is hi-res. For most people who watch TV through cable, streaming, or antenna, the audio is not hi-res, so the feature offers no practical benefit. If you have a collection of Blu-ray discs or subscribe to a hi-res music streaming service, then a soundbar with hi-res support and HDMI eARC can be a worthwhile consideration.

When comparing soundbars, focus first on the channel layout, subwoofer configuration, and connectivity that match your TV and room. Hi-res audio is a secondary feature that becomes relevant only after those basics are met.

What to pick for your situation

Questions

What is hi-res audio?

Hi-res audio refers to audio files that have a higher sampling rate and bit depth than CD-quality audio (44.1kHz/16-bit). Common hi-res formats include 96kHz/24-bit and 192kHz/24-bit. The term is used on soundbar listings to indicate the product can process such files.

Do I need hi-res audio for Netflix?

No. Netflix and most streaming services use compressed audio formats like Dolby Digital Plus, which are not hi-res. Hi-res audio support does not affect your Netflix experience.

Can I get hi-res audio over Bluetooth?

It depends on the Bluetooth codec. Some soundbars support codecs like LDAC or aptX HD that can carry hi-res audio, but the listing may not specify. For guaranteed hi-res playback, use a wired HDMI eARC connection.

Is hi-res audio the same as Dolby Atmos?

No. Dolby Atmos is an object-based surround sound format that can be delivered in both lossy and lossless (hi-res) versions. Hi-res audio refers to the resolution of the audio signal, not the spatial format. A soundbar can support Dolby Atmos without being hi-res certified.

How do I know if my soundbar supports hi-res audio?

Check the listing for phrases like "Hi-Res Audio Certified" or "24-bit/96kHz." If not listed, visit the manufacturer's product page for detailed specifications.

Does hi-res audio make a difference on a soundbar?

Hi-res audio files contain more data than standard files, but whether you hear a difference depends on your source material, your listening environment, and your own hearing. This site cannot comment on audible differences.

Should I pay extra for hi-res audio support?

Only if you regularly play hi-res content from Blu-ray discs or hi-res music services. For typical TV and streaming, the extra cost may not provide a benefit. See the best soundbar guide for options at different price tiers.

What connections do I need for hi-res audio?

HDMI eARC is the most reliable connection for hi-res multichannel audio. Optical is limited to 48kHz/24-bit. USB input may support hi-res stereo files. Check the soundbar's specifications for supported sample rates.
