About MP3
MP3 (MPEG-1 Audio Layer III) is a lossy audio format from the early 1990s. It removes the sound listeners are least likely to notice, typically at 128 to 320 kbit/s.
It plays on virtually every device and app, which makes it the default for music files, podcasts and audiobooks.
MP3 tops out at 320 kbit/s and two channels, and every re-encode removes a little more detail.
Why convert music to MP3? Every device, car stereo and app made in the last 25 years plays it, so nothing and nobody is left out.
What changes when you convert WMV to MP3
- The soundtrack of the WMV is re-encoded as MP3 at the default settings, so it is close to the original but not bit-identical.
- Only the sound is kept: the MP3 file contains the audio track of your WMV, and the picture is dropped.
- WMV files can carry DRM copy protection; protected files are detected and refused, because copy protection is never removed.
