And isn’t that what we want?Īlthough hi-res audio songs and albums have been available to download for several years now, streaming hi-res audio is relatively new across popular music subscription platforms - and some still don’t offer it. Provided your system is transparent enough, playing hi-res music can bring you more detail and texture, thus bringing you closer to what the artist wanted to say when they recorded their work.
Music CDs are kbps - remember, they’re your starting marker for hi-res. The highest quality MP3 has a bitrate of kbps. To illustrate why hi-res should sound better than, say, an MP3, we need simply to compare the relative bitrates the amount of information being transferred measured in kilobits per second. Obviously, this affects the sound quality. This ‘lossy’ compression means that certain data is scrapped in the encoding process for the sake of convenience and smaller file sizes.

Streams from Spotify and Apple Music use compressed file formats with relatively low bitrates, such as kbps Ogg Vorbis streams on Spotify Premium if you’re a Spotify Free user, your file quality will actually max out at kbps and kbps AAC files on Apple Music. In numbers, it’s a jump from 96dB to dB, which is huge. Going from 16 bits to 24 bits results in a massive increase of dynamic range, which is the gap between the quietest and loudest sounds that can be captured. The first number is bit-depth, which indicates the number of ‘bits’ of information present in each sample of the signal. The higher the sampling rate, the more times the audio signal has been sampled, and thus the more detail resolution you get. Sampling rate - the second number - refers to the number of times per second that the wave is measured during the analogue-to-digital conversion process. First things first, should you care about hi-res streaming? So what do the numbers mean? It might help to think of an audio signal as a sound wave being plotted on a graph. Get ready: your music is about to sound a lot better. How will they convince customers to stick around for hi-res audio at comparatively hiked prices next to the likes of Apple and Amazon? Below, we try to help you decide just that, starting with the differences between lossless and hi-res music, and offering a breakdown of the services and their USPs. So where does the arrival of these newer, competitively priced hi-res services leave Tidal and Qobuz, and even services not in the hi-res game Deezer, for example, ‘only’ offers CD quality? So, is Tidal HiFi Plus the answer? It’s certainly one answer, but there are other options There’s also Amazon, which announced in May that its hi-res-inclusive Music HD tier which we called "up there with the best” was now free for all Amazon Music Unlimited subscribers. It is our favourite service, too, and holder of a What Hi-Fi?Īward in the music streaming service category. Tidal is perhaps the most established in this realm. In, the key to victory is ad-free, unlimited streaming in high-resolution quality - and, crucially, for the best price. Gone are the days when all a streaming platform had to do was offer up low-quality Ogg Vorbis or MP3 streams and make you endure a few ads for the privilege. The battle to become the best music streaming service offering hi-res streams is well and truly underway.
