Comment 7 for bug 574921

I don't think is a user mistake, or a invalid bug report. I reproduce it:
1) Open a .m4a audio file.
2) Concert to: Audio. Device preset: MP3
3) Bitrate: 64. Sample Rate: 22000. Audio channels: 1
I believe a GUI should made things more easy and a friendly way to avoid users errors, with for example comboboxes and presets options...
