WAV vs MP3

The core difference

A WAV file stores audio uncompressed, keeping the full detail of the recording. That makes it the format of choice for mastering, distribution, and archiving, at the cost of a large file size (tens of megabytes per song). An MP3 uses lossy compression to shrink the file dramatically, permanently discarding audio information the format judges least audible.

For most listening, a high-bitrate MP3 sounds excellent and is far more practical. But once quality is discarded by MP3 compression, it cannot be recovered, which is why anything headed for mastering or a distributor should be a WAV.

Which should you use

Deliver a WAV when it matters: to a mastering engineer or masterer, to a distributor, or into an album archive. Use an MP3 for quick sharing, demos, and casual playback. On AetherWave, your first master is free and comes back as a genuine 24-bit / 48 kHz WAV, so you always have the high-quality version when you need it.

Frequently Asked Questions

Is WAV better than MP3?

WAV preserves full, uncompressed quality, so it is better for mastering, distribution, and archiving. MP3 is lossy but far smaller and fine for casual listening. Each is better for a different job.

Can I convert an MP3 to WAV to improve quality?

No. Converting an MP3 to WAV does not restore the detail MP3 compression discarded. For genuine quality, start from a lossless WAV source.

Which format should I send to a distributor?

A WAV. Distributors and mastering engineers want the uncompressed, full-quality file. AetherWave delivers a 24-bit / 48 kHz WAV from mastering.
