Repair M4A

This audio tool will try to repair M4A audio files that cannot be played due to accidental truncation and corruption. It will extract and convert as much data from the damaged audio as possible. The tool provides two repair methods: "No Reference" and "Reference". Using the "No Reference" option, the tool can only repair single-channel (mono) or dual-channel (stereo) M4A audio, the truncated file must have complete metadata header information. Using the "Reference" option, you should provide a good audio as a reference file, this reference audio should be able to play normally and should come from the same device as the damaged audio, for example from the same mobile phone.
