Audio File Formats: WAV, MP3, and What to Use When

The format you record and export in affects everything from sound quality to file size, and mixing them up is a common beginner stumble. Record in one format and deliver in another, for good reason.

Choose the right format for each stage.

1. Record in uncompressed WAV at twenty-four bit for maximum quality.
2. Edit in WAV to avoid re-compressing the audio repeatedly.
3. Export the final master as a high-bitrate MP3 or AAC.
4. Keep the WAV master archived for future re-edits.

The rule is simple: record and edit lossless, deliver compressed. Starting with MP3 bakes in quality loss that no amount of editing can recover.

The archive is the part beginners forget. Keep the WAV masters, because a future re-edit or remaster starts from the best source, not from a compressed copy that has already thrown away detail you cannot get back.
