What Is Lossless Audio?
Lossless audio explained: what lossless means, how FLAC, WAV and ALAC compare, and why it matters for listening and music distribution.
Lossless audio preserves the full detail of a recording by compressing it without losing any data. Formats like FLAC, ALAC and WAV contain every bit of the original master, unlike lossy formats such as MP3 that discard data to save space.
Lossless vs lossy
Lossy formats like MP3 and AAC remove audio data the human ear perceives poorly, shrinking file size but reducing fidelity. Lossless formats keep 100% of the source data, so playback is bit-for-bit identical to the master.
Whether the difference is audible depends on your ears, gear and listening habits — but lossless always retains maximum quality.
Common lossless formats
WAV is uncompressed lossless — large but universally supported. FLAC compresses losslessly to roughly half the size and is the streaming-friendly favourite. ALAC is Apple's lossless codec.
For distribution, always upload the highest-quality lossless source available so platforms can transcode optimally.
Lossless streaming
Many streaming services now offer a lossless or hi-res tier. These deliver full-quality audio to subscribers, making master quality more important than ever.
Zaventra Music Group supports high-resolution lossless delivery, so your catalog can take advantage of these premium tiers.
