[MPlayer-users] mp3 playing with mplayer without soundcard

[zonyi besk]

Than  have to update the task with mplayer,  it's
-playing one sound without soundcard in command line
-in real time, to be clear: 3 min mp3 file would play during 3 min not in
one sec
-while playing modifying volume, equalizer, speed via input file option or
other way
-creating output wav or mp3 or similar to file or stdout

Are these possible and which command can do that?

Thanks,
Regards,
Zol
