2. Pick the sample rate and bit depth, or keep the source values to avoid any change.
3. Click Convert. Processing happens on your device and shows progress; you can cancel at any time.
4. Preview the result and download the WAV file. With several files, download them all as one ZIP.

About M4A to WAV conversion

M4A (MPEG-4 Audio, AAC in an MP4 container) suits iPhone and Apple Music libraries, ringtones (.m4r), and better quality than MP3 at the same size. WAV (Waveform Audio File Format, RIFF container) suits editing, mastering, sampling and handing audio between programs without quality loss.

M4A is lossy, and no converter can restore detail that was already discarded. The WAV file will sound the same as the M4A source and will be larger; the point of the conversion is compatibility with software or hardware that needs WAV.

For a 4-minute track, a typical M4A file is about 5 MB and a typical WAV file is about 42 MB. Your own result depends on the bitrate and the audio itself.

M4A vs WAV

WAV support: Opens in every audio editor and operating system. Browsers and phones play it, though not every player shows tags.

M4A support: Native on Apple devices, Android and Windows. Older car stereos and some budget players may refuse it.

Quality and compatibility notes

• WAV: Large files: about 10 MB per minute at CD quality. The classic format stops at 4 GB, which RF64 extends.
• M4A: The same file can hold lossless Apple Lossless (ALAC), so the extension alone does not tell you whether it is lossy.
• Tags: WAV stores limited: RIFF INFO chunks, and BWF or iXML metadata in broadcast files.
