Higher video resolution means more pixels on a screen, which produces a more detailed image. To understand hi-res audio (HRA), it helps to think about video resolution. For the true audiophile, Apple Music also offers Hi-Resolution Lossless all the way up to 24 bit at 192 kHz," the company said. "Apple Music’s Lossless tier starts at CD quality, which is 16 bit at 44.1 kHz (kilohertz), and goes up to 24 bit at 48 kHz and is playable natively on Apple devices. (More on that later.) What is hi-res audio?Īpple Music's new lossless audio option comes in several tiers. All of these should sound pretty much the same - that's the whole point of lossless audio - but the discrepancy does have consequences for the end user.
Tidal uses a widely-used codec called FLAC. Apple uses something called ALAC for Spotify, we don't know which codec the company will use, but it almost certainly won't be ALAC, which is Apple's proprietary codec.
For example, Apple and Spotify are using different lossless audio codecs (a codec is software that encodes and decodes audio data). In an ideal world, all services and gadgets would be fully compatible with each other. But now that Apple and Spotify are going lossless, you should take advantage if you can. That's alright for certain scenarios, like when you're on a pricey mobile connection. However, most popular audio streaming services still default to lossy compression audio - MP3, in Spotify (opens in a new tab)'s case, and AAC, in Apple's case. Connections are faster and hard drives are big and cheap. MP3 was a brilliant invention, allowing people to transfer decent-sounding audio online in the early 2000s, when connections were slow and hard drives were small. It works by removing the sounds that humans can't hear anyway, such as very high- or low-frequency sounds, and using a bunch of other tricks, such as merging the audio data from the left and right stereo channel into one. The beauty of MP3 is the ability to take an uncompressed audio file - say, a file in WAV format - and reduce its size tenfold, while still sounding pretty good. To understand the term, we need to go back to the MP3 format, which popularized lossy compression - that is, audio data compression that results in some data loss, but ideally produces much smaller files. Other music streaming services, such as Tidal, have offered lossless streaming for years.īut do you really need this feature? Even more importantly, is it worth upgrading your audio equipment to fully enjoy the benefits of lossless audio? And if so, which speakers or headphones should you get? Read on. Apple will offer it in June, and Spotify will offer it.well, we're not sure yet, but probably very soon.
Apple Music and Spotify both announced they will offer lossless audio streaming.
