Kept

  • Sample rate and channels (mono, stereo, even 5.1 surround) are read as they are

  • Saved as M4A (AAC) at 192 kbps, which plays on iPhone, iTunes, Apple Music and almost every modern player

WAV vs M4A

WAV

A WAV file stores audio completely uncompressed — full quality, but large file sizes. It's the standard for professional audio editing, recording, and mastering, where quality matters more than size.

Used in: Audio editing & mastering · Professional recording · Sound design

M4A

An M4A file is a compressed audio format (usually AAC inside an MP4 container) used by Apple's ecosystem — iTunes, Apple Music, and voice memos on iPhone all default to it. Slightly better quality than MP3 at the same file size.

Used in: Apple Music & iTunes · iPhone voice memos · Audiobooks
