WAV (hi-res): The standard format in which all CDs are encoded. The file format used (at 320kbps) in Spotify streaming. A lossy, open-source alternative to MP3 and AAC, unrestricted by patents.
OGG (not hi-res): Sometimes called by its full name, Ogg Vorbis. MQA (hi-res): A lossless compression format that packages hi-res files for more efficient streaming. Convenient for storing music on smartphones and iPods. MP3 (not hi-res): Popular, lossy compressed format ensures small file size, but far from the best sound quality. The downside is, it’s not supported by Apple (so not compatible with Apple Music). It's royalty-free and is considered the preferred format for downloading and storing hi-res albums. Uncompressed.įLAC (hi-res): This lossless compression format supports hi-res sample rates, takes up about half the space of WAV, and stores metadata. It comes in 2.8mHz, 5.6mHz and 11.2mHz varieties, but due to its high-quality codec, it’s (mostly) impractical for streaming. It is lossless and uncompressed (so big file sizes), but not hugely popular.ĭSD (hi-res): The single-bit format used for Super Audio CDs. Used for Apple Music streaming.ĪIFF (hi-res): Apple's alternative to WAV, with better metadata support. Lossy and compressed, but sounds generally better. AAC (not hi-res): Apple's alternative to MP3 – stands for 'Advanced Audio Coding'.
