Best Audio Format for Mastering

Give the master the best source

Mastering works on your finished mix, so it can only be as good as the file you provide. The standard is a lossless WAV at 24-bit, at either 44.1 or 48 kHz, bounced with a few decibels of headroom (peaks around -3 to -6 dB) and no clipping or limiting on the master bus. That gives the mastering process room to work.

Sending an MP3 is the one thing to avoid: the compression has already removed detail, and mastering cannot bring it back. Always master from a lossless source.

Master free, get a WAV back

Bounce a clean 24-bit WAV of your mix, then master it on AetherWave. Your first master is free, and it comes back as a finished 24-bit / 48 kHz WAV ready for release.

What format should I export for mastering?

A lossless WAV at 24-bit, 44.1 or 48 kHz, with a few dB of headroom and no clipping. Avoid MP3, since mastering cannot restore lost detail.

How much headroom should I leave before mastering?

Aim for peaks around -3 to -6 dB with no limiting on the master bus, so the mastering process has room to work.
