02 / what you get

What happens to your data

Kept

  • Raw AAC (ADTS) streams with the .aac extension are supported
  • Saved as M4A (AAC) at 192 kbps, which plays on iPhone, iTunes, Apple Music and almost every modern player

Good to know

  • Raw AAC files carry no title, artist or album tags, so there is nothing to copy over.
  • Both formats compress with quality loss, so every conversion costs a little quality. Keep your AAC original.
