By now most of us have opted in to one of the subscription music streaming services and many of us also rely on YouTube for music content streaming. We use these sources for recreation and also for accessing reference music we need in our professional lives as creators. For many years, we’ve had to accept low-quality, lossy formats for portable listening and streaming over slow or data-restricted networks. High-quality audio was reserved for our DAW output and music that we could purchase or rip in hi-res formats. 2021 brings us the luxury of unlimited data caps (for most of us) and streaming services that have entered the modern age of streaming high-quality, lossless audio. 

If it’s been a minute since you’ve compared your streaming plan to your needs and desires for high-quality streaming, take some time to revisit what is available and which features you can take advantage of. Three questions should be considered when judging a streaming service: where and how will you be listening, what are your quality requirements/goals, and is streaming enough, or would you also like downloadable music to reference offline.

How and Where Do You Listen?

During a workout, while driving, or while doing yardwork audio quality is not as much a concern as the variety of content. Noisy environments, cheap earbuds, and many Bluetooth devices don’t provide an opportunity to take advantage of high-resolution audio, so if these are your main listening conditions, you might opt for a service with lots of content without much concern for the resolution/quality options.  

If you mostly stream on studio monitors/headphones, on a full range home stereo or theater system, or even in many new cars, the quality of your audio stream matters more, as you will be able to discern between low-bitrate codecs and hi-resolution streams. 

What Are Your Quality Goals?

If you mainly stream music during your workouts or if you mainly stream podcasts or talk-radio-type content, then the quality of the stream won’t be too much of a concern. If you stream to enjoy the fidelity of music or if you use streaming as a reference for your music production work, you will probably want to opt for a service that provides high-resolution, lossless audio.

Do You Stream or Listen Offline?

At times it may not be convenient or possible to log into a wifi or cell network—like on an airplane or even in a large office building—so you may prefer to download content that you can listen to even when you’re offline. Your device storage may limit the amount of data you can store, which in turn may limit the resolution of the audio you wish to store. Conversely, if you wish to import music into your DAW for reference during your music production sessions, you will certainly want to be able to download lossless audio formats that your DAW can import without much fuss.

Current Audio Formats from Streaming Services

Comparing streaming services can be a bit like shopping for a mattress. Every platform uses unique terminology to describe its content quality making it difficult to compare against other providers. HiRes, HiFi, HiDef, Lossless, Master Quality, CD-Quality, Uncompressed, Standard, Immersive… these are but a few of the descriptors used by various streaming services to assure the customer of the quality they are providing. Furthermore, most record companies and artists provide distributors with only one master, so each platform will convert that master to their own formats.

CD-spec or Hi-Res audio describes audio that is at least 16-bit/ 44.1 kHz PCM audio (.wav or AIFF) files. In all practicality, 16-bit 44.1 kHz masters should sound identical to any higher resolution format. Your own equipment may sound different (due to its own performance limitations) at different sample rates, bit depths, or with different Hi-Res formats, like DSD, but these formats all match or exceed the fidelity of the original master file. 

Lossless encoding reduces the size of an audio file by as much as 50%, but no audio data or audio quality is lost when the file size is reduced. Lossless files come in different resolutions, all of which meet or exceed CD-spec. FLAC and ALAC are common lossless audio codecs. Not every audio player or DAW can play or import FLAC/ALAC files without first converting them back to .wav of AIFF.

Lossy codecs reduce the size of an audio file by discarding audio data that can never be recovered, so they will sound inferior to the original source. Lossy codecs (reasonably good-sounding ones) can reduce the file size by as much as 90%. MP3, AAC, Ogg Vorbis, and Opus are commonly used lossy audio codecs.

Immersive Audio formats commonly include Dolby Atmos, Sony 360 Reality Audio, Dolby Digital, and AC-3, and Apple’s Spatial Audio formats. These formats may be lossy or lossless encodings and many audio titles are upmixed, or derived from the original stereo mix electronically, and not produced specifically to be heard as immersive audio. These upmixed or remixed versions are often produced by the distributor and not by the original artist or producer.

Alternative formats, like MQA (currently used by TIDAL) or any other format claiming to provide “master quality” or “music as the artist intended,” should be questioned and likely do not provide the resolution they claim or infer. This is not to say they don’t sound acceptable or even excellent, but their marketing tends to be misleading or false. If you use a service that provides anything except the well-defined lossless or lossy codecs defined above, you should do your own due diligence and listening tests to see if you are satisfied with the audio quality. MQA has been accused of misleading consumers as to its lossless quality claims, but many mastering engineers praise its sound. As the saying goes, “let the buyer beware.”

Many computers and portable devices will not properly play audio formats above 24-bit/48 kHz, so an external DAC (USB, optical, or Thunderbolt) may be required to enjoy the files’ full resolution. Additionally, some formats, like DSD, MQA, FLAC, and ALAC may require specific hardware or software players or format converters for their playback or conversion to a format that you can easily enjoy (or import into your DAW).

To help understand the levels of quality, here is a list of the current streaming formats available and how they stack up. Further down we’ll examine which services provide which formats.

Remember to think about how you will utilize a streaming service and then determine which audio quality you prefer. Then you can determine which service provides the best price vs. performance and if you will need any additional hardware or software to enjoy that service. Lastly, keep in mind that 16-bit 44.1 kHz is considered master quality and anything above that will not improve the sound of a master. Bandwidth is cheap, so enjoy high-quality streaming!
