The best export preserves the session accurately and matches the next stage of the project.
Export settings should be chosen for a destination: mix review, mastering, distribution, video or archive. Creating one compressed file and using it for every purpose introduces avoidable conversion and makes later revisions harder.
Export a mix for mastering
Use WAV or AIFF at the session sample rate and native high bit depth, commonly 24-bit or 32-bit float when requested. Keep the approved mix-bus processing, but avoid unnecessary loudness limiting. Export from a clean start point and include the full reverb tail.
Create final distribution files
Follow the distributor or client specification, because requirements can change. A high-resolution WAV is the dependable master source. Create MP3 or AAC listening copies from that master rather than using a lossy file as the source for another conversion.
Apply dither at the correct moment
Dither is relevant when reducing bit depth, such as creating a 16-bit file from a higher-resolution master. Apply it once at the final reduction stage. Do not add dither repeatedly to intermediate files or when no bit-depth reduction occurs.
Name and verify every version
Use clear names containing artist, title, version, sample rate or date when useful. Listen to the exported file from beginning to end, check duration and confirm that no normalization or automatic conversion was enabled unexpectedly. Store an approved master separately from working versions.
Practical checklist
- Use lossless WAV or AIFF for masters.
- Keep the session sample rate.
- Avoid automatic normalization unless required.
- Dither only at final bit-depth reduction.
- Listen to the actual exported file.
Frequently asked questions
Should I export 32-bit float for mastering?
It can preserve overs and processing precision, but many mastering workflows prefer a clean 24-bit file. Ask the engineer rather than assuming.
Is MP3 acceptable for distribution?
Use a lossless master for delivery whenever possible. Compressed copies are useful for previews and specific platforms that request them.
Final takeaway
Export once from the best source, verify the result and create destination-specific copies from that approved master.
