File preparation guide
Mastering Preparation
A clean, lossless stereo mix gives mastering the best possible starting point.
Export format
Export the final stereo mix as WAV or AIFF, preferably 24-bit, at the same sample rate used in the session.
- Do not convert an MP3 back to WAV.
- Keep the original sample rate; do not upsample solely for mastering.
- Export one continuous stereo file from the intended start to the intended end.
Master-bus processing
Remove final loudness processors that leave no room to work, while keeping processing that is an intentional part of the mix sound.
- Disable brick-wall limiting, maximising and accidental clipping.
- Bus compression, EQ or saturation may stay if they are essential to the mix.
- There is no fixed −6 dB target. Clean, unclipped peaks and natural headroom are what matter.
Check the render
Listen to the exported file from beginning to end before uploading it.
- Check the first and last notes, fades and reverb tails.
- Make sure there are no clicks, dropouts or muted elements.
- Compare the render with the session at the same playback level.
References and notes
A concise brief makes the first master more focused.
- Include one or two relevant reference tracks.
- Describe the desired direction: warmer, brighter, punchier, wider or more dynamic.
- Mention any concern you do not want mastering to exaggerate.
Before uploading
WAV/AIFF · preferably 24-bit · original sample rate · no clipping · limiter removed · file checked from start to finish.
