Frequently asked questions
Can it convert iPhone voice memos?
Yes. Voice memos are AAC audio in an M4A file, which the converter decodes and saves as WAV.
Will protected music from Apple Music work?
No. DRM-protected files cannot be decoded. Unprotected M4A files, such as your own recordings and purchased iTunes Plus tracks, convert normally.
Why is the WAV so large?
WAV is uncompressed, about 5MB per minute for 48 kHz mono and 10MB per minute for stereo, while M4A is compressed.
Is there a size limit?
The first conversion downloads about 32 MB of processing code. Files are processed one at a time on your device and kept in memory, so very long recordings need a device with plenty of RAM.
Is it private?
Yes. Your recordings stay on your device.
