Display MP3 stereo waveform

[AlanHK]

How can I see the waveforms of both channels of an MP3 quickly?

Is there some simple (free) audio player with a stereo wave display?

I know I can load it in Audacity, but that can take quite a while (with multiple hour long tracks as book readings usually are), as it decodes the entire track before displaying it.

MP3DirectCut does display a waveform immediately, but it only shows a single merged track.

One reason I'd like to do this is so I can skip through a track and see if it is true stereo, or if both tracks are identical and I can split it without loss.

and to make your life easier bellow ready to use command:

@ffplay -f lavfi amovie=%1,asplit[out0],showwaves=split_channels=1:s=1024x768:mode=p2p:rate=60[out1]

VLC's "scope" visualization shows the waveform. You have very little control though.

Thanks, that does the job.
