The problem
Sending a listening sample and keeping a recording for editing have different needs. The smallest output is not always suitable for later work.
A practical answer
GJ File Manager's audio conversion includes M4A/AAC, ALAC, MP3, FLAC, WAV and AIFF choices. Establish what the receiving software accepts, then test a sample.
Step by step
- Decide whether the output is for listening, editing or retaining material, and confirm accepted formats.
- Add the original audio and choose a compatible output.
- Keep source sample rate and channels unless the task calls for a change; choose a bitrate when using lossy encoding.
- Export separately, listen and check duration, channels and size before processing the remaining files.
Know the limits
Converting MP3 or AAC to a lossless or uncompressed format cannot restore lost detail. A larger file does not prove better sound.
Common question
Should everyone use the same format?
No. Compatibility, further editing and transfer size differ; verify the actual receiving workflow.
