Use WAV when possible
WAV is a strong choice for mastering because it is not compressed like MP3. It preserves more detail and gives the mastering process a better source file.
If you are working from a podcast editor, DAW, video editor, or recording app, look for WAV export when available.
Avoid clipping
Do not export a file that is already hitting red or sounding distorted. Clipping creates harshness that mastering cannot fully repair.
Lower the output slightly if needed and keep the final file clean.
Do not over-compress before mastering
Heavy compression, limiting, or loudness maximizing before mastering can make the final result less flexible.
Use enough processing to make the mix sound right, but avoid crushing the final output before uploading.
Name and organize your files clearly
Use a clear filename that identifies the track, episode, or project. This helps you keep original mixes, mastered versions, and revisions organized.
Keep a backup of the original export in case you need to return to it later.
Final thought
A good export is clean, complete, unclipped, and high quality. That simple preparation can make the mastering step smoother and more effective.
