What this audio operation changes
Trim a compatible M4A recording and download WAV. Unlike an audio format swap, this operation alters decoded audio samples before exporting them.
The result is WAV audio, which is suitable for further editing but may be larger than the original compressed recording. Keep the original if you may need to undo the edit.

About this tool
Trim a compatible M4A recording and download WAV.
WAV output can be larger than the input. Audio decoding requires format support in your browser. No MP3 encoding is provided.
Practical questions
What does this tool produce?
The tool applies the requested change to decoded audio samples and exports the result. It does not rewrite the original file in place. The source audio is decoded before export. Output encoding and compatibility depend on the selected format and the codecs available in the browser.
What should I check before using the result?
WAV output is uncompressed PCM and is often much larger than MP3, AAC or Opus; decoding a lossy source into WAV does not recover discarded quality. Listen to the result for clicks, clipping, abrupt cuts or altered loudness. Keep the original recording for further edits.
