Why convert WMA to AAC?

  • Get old Windows rips onto iPhone and iPad, which have no WMA support at all.
  • Upload legacy recordings to platforms and apps built around the MP4/AAC family.
  • Trade a fading proprietary codec for one with hardware decoding in essentially every modern device.

Tip: Most 2000s WMA files were encoded at 64-128 kbps, so the source sets the quality ceiling — converting at 192 kbps AAC avoids adding audible loss on top.
