#178 Waveform Display for SoX
It would super useful to have the functionality for rendering a waveform display to an image directly in SoX. For me it's often the only 'missing link' when using SoX as an audio editor, as resorting to third-party apps can interrupt the workflow. I don't mean anything sophisticated, just downsampling a waveform and dumping it into an image. Since the functionality for rendering spectrograms is already there it seems it shouldn't be too difficult to render an image of the time-domain data instead? I think this could be useful in a variety of contexts/applications. I'm aware SoX is intended as a command-line tool, but since the spectrogram functionality (which I find very useful) is already there, it doesn't seem to far and would be useful to have. Personally, one of the typical workflows with SoX in which I have to resort to external applications is to get an idea of the waveform, e.g. for visually finding a loop/cue point, etc. then running a command etc.

I'm waiting this waveform feature from a long time also... It's really missing. I can't find any other command line tool that generates waveform...
One possible workaround would be to get the time-domain sample values and use gnu plot - I think to remember there's an option for this.
