I already pretty much do what you describe using the sox and play(1)
commands with trim.
I'm not _totally_ anti-GUI :) I also combine sox trim with the
spectrogram effect of sox (w/ feh to open the .png) to visualize
portions of tracks. I also use --plot=gnuplot with sox to
visualize EQ curves.
If I built a tool it'd support several command-line tools (starting with
SoX and ecasound, but maybe ecasound+LADSPA/LV2 can do everything SoX
does...).
