M4A requires dedicated audio editors to preserve its original quality. For this reason, you will need the best M4A editor for this task. Therefore, to help you on this matter, we gathered 7 best M4A editing programs that fit your needs.
Quick Overview: What Is M4A
M4A is a popular audio format for iTunes. M4A stands for MPEG-4 Audio – it is a compressed audio file within an MPEG-4 file container. It is encoded by default with AAC (Advanced Audio Coding), which uses lossy compression to reduce file size.
- M4A editing faces a long-standing problem: quality loss. Most audio editors don't edit the compressed file directly. Rather, they decode it first, perform the edits, and then re-encode it back into the compressed format. This process hurts AAC more than other codecs because AAC is lossy. Every time you edit the M4A audio, it gets re-compressed and thus loses quality.
