What is a M4A file?
.m4a is the generic extension for audio‑only MP4 files. Inside, you will typically find AAC or ALAC streams plus metadata for chapters, cover art, and lyrics. The format provides gapless playback, efficient compression, and wide ecosystem support. Apple coined .m4a in 2001 to distinguish music downloads from copy‑protected .m4p tracks sold on the iTunes Store. Because MP4’s audio profiles required no licence fees, many podcasters and game developers adopted .m4a for better quality than MP3 at the same bit‑rate. Today .m4a is recognised by Android, Windows, and most car infotainment systems.
What is a WAV file?
WAV is Microsoft and IBM’s RIFF‑based wrapper for PCM or ADPCM audio. It stores data in little‑endian ‘fmt ’ and ‘data’ chunks, making parsing trivial and ensuring universal DAW support. Introduced in 1991 alongside Windows 3.1’s Multimedia Extensions, WAV replaced raw VOC and AU formats. Its 4 GiB limit was a drawback until RF64 and W64 extensions arrived, but for most pop songs the cap is moot.
