Recently, my Japanese teacher has been sending me audio dictations in mp4 formats. It’s not a problem in itself since MPlayer or any other Linux player can read it. But nothing beats Audacity for listening and re-listening the hard parts (and change the tempo when things get really hard) but it doesn’t support MPA’s (or rather, it simply and unequivocally crashes). For the last 3 or 4 lessons, I still haven’t mastered this single line of Kung Fu to convert it with MPlayer:
mplayer -ao pcm:file=<out file>.wav <in file>.mpa
Notice how the pcm:file replaces the old syntax. MPlayer (on Ubuntu at least) will warn you about this.
Hopefully I’ll stop scouring the ‘Net and go straight to this page if my memory fails. And I hope you do too 😉
