The term "hi-fi," which stands for high fidelity, doesn't have an exact definition any more. (This is how Apple, with its new lossless audio codec, ALAC, is going to persuade music enthusiasts who own an iPhone to switch over to Apple Music.) Is "lossless" the same thing as "hi-fi"? This means that if you have an iPhone or Mac and you subscribe to a lossless streaming service that plays FLAC digital audio files, you won't be able to play your music in its full lossless glory. FLAC music files have been popular for years, but the downside is that they are not supported by Apple's devices and services. FLAC (Free Lossless Audio Codec) and ALAC (Apple Lossless Audio Codec) are two of the most common. There are several different lossless audio codecs, which are digital music file formats that support lossless and CD quality audio. However, these audio files aren't lossless (which is 1,411 kbps). For example, if your smartphone and headphones support either of some audio codecs, such as Sony's LDAC (up to 990kbps) or Qualcomm's aptX Adaptive (up to 570 kbps), you can stream stream high bitrate and low latency audio files over Bluetooth. There are technologies that let you stream high bitrate audio over Bluetooth. Or you can stream the lossless audio over a Wi-Fi, through a pair of active speakers, such as KEF Wireless II or even multi-room speaker like Sonos (thanks to Qobuz). You can use an analog connection, like connecting your wired headphones to your smartphone or computer. In order to listen to lossless digital audio files, you have two main options. So if you're wondering whether your audio equipment (and ears) can do justice to higher bitrate tunes, a great way to find out is experiment with telling the difference between the various flavors of lossiness streaming services already give you.Ĭan lossless audio be streamed over Bluetooth? This is over four times the audio quality of an MP3 file (with a bitrate or 320 kbps). The bitrate of a normal lossless audio track is around 1,411 kbps. Spotify's default or "normal" setting delivers audio with a bitrate 96 kbps. But that's only if you've flipped some switches in settings. If you've been a paying subscriber to a streaming service like Spotify or Apple Music for years, you've been listening to digital audio files with a max bitrate of 320 kbps and 256 kbps, respectively, which is about the same audio quality of an MP3. The lower the bitrate, the less information and the worse a digital audio file is going to sound. The bitrate of a digital audio file, or the amount of data transferred per second, is the primary metric we use to determine audio quality. How does lossless audio compare to the music I'm already streaming? And not every lossless streaming service supports them. The catch is that most lossless streaming services don't have a huge catalog of these ultra high-resolution audio tracks. For example, Tidal gives its HiFi subscribers the option of listening to Master Quality Authenticated (MQA) certified tracks (up to 24bit/96kHz), while Amazon Music HD gives its subscribers the ability to listen to "Ultra HD" (up to 24-bit/192kHz). In popular use "lossless" means the same quality as a CD (16-bit/44.1 kHz), but there are a number of lossless streaming services that offer even higher-quality digital audio files. Lossless just means that no detail has been destroyed in the compression process the quality of the lossless file therefore depends on the original source that's being compressed. The average size of lossless compressed audio file, such as FLAC or ALAC (Apple Lossless), is now a little more than 1/2 the size of its original recording.Īpple Is there anything better than lossless? For context, the average size of a compressed audio file, like a MP3 or a AAC, is about 1/4 the size of its original recording. "Lossless" doesn't mean uncompressed, but rather it refers to a type of compressed digital audio file that uses advantaged data compression algorithms so that the audio track doesn't "lose" any detail in the compression process. This squishing process is "lossy" the end result is missing detail that the previous, unsquished version had, specifically at the low and high ends, so that it doesn't sound nearly as good. These are files that have pointedly squished so they take up less storage space on your smartphone or digital music player.
