Voice Memos, GarageBand AAC exports and iTunes purchases all produce compressed M4A. That suits a phone, but many samplers, older DAWs and voice tools only import WAV, and Audacity needs an extra FFmpeg library before it will open M4A at all.
The WAV holds the decoded sound as plain PCM samples, so editing, cutting and noise reduction never add another round of compression. The cost is size. A minute of 44.1 kHz stereo WAV is roughly 10 MB, against about 1 MB for a typical M4A.
Converting does not undo the compression the M4A already has, so record the source at the best quality setting your phone offers. In Voice Memos that means switching Audio Quality to Lossless in Settings before you record. Trim silence at the start and end after converting.
WAV stores audio uncompressed. A minute of stereo WAV is about 10 MB, several times larger than the same M4A. The sound does not get better, but editors can work with it without re-compressing.
Yes. Most voice cloning tools prefer clean WAV samples. Record in a quiet room, convert here, and trim any silence before uploading your sample.
No. It converts inside your browser, on your own device. Nothing reaches FacelessGenie or any other server.
Files up to 1 GB work. Long recordings simply take longer on slower devices.
Recent Chrome, Edge and Safari handle every format here. Firefox opens most audio. For WAV problems, Chrome or Edge is the safest retry.
