Your demo is ready to send. You want it to download quickly, open easily, and sound good. It helps to separate two jobs: keeping your work and preparing a copy for its next destination.
1. Keep the source.
If your recording or finished mix is available as uncompressed PCM WAV or FLAC, keep that version. FLAC reduces file size without losing audio data. After editing, save a lossless version of the finished result too, so future exports can start there.
2. Choose for the destination.
MP3 or AAC can work for a quick listen if the recipient’s device supports them. For further editing, check the required format and settings: your collaborator may need WAV at a particular sample rate and bit depth. The project’s requirements matter more than choosing the biggest numbers.
3. Make each copy from the saved version.
WAV → MP3 → AAC → MP3 means several rounds of lossy encoding. Each round can introduce further degradation. Create MP3 and AAC copies separately from the same finished WAV or FLAC instead.
Converting MP3 to WAV cannot recover detail lost during compression. It can help with compatibility, but a larger file alone brings no improvement in sound.
AudioFlow makes these copies locally on your Mac and preserves the source. Before sending, open the exported file and listen to the beginning, end, and a familiar passage. It is quicker than explaining where the last chord went.
