That seems strange - the silence effect inspects the silence - if it's preceded by 10 seconds or 30 seconds of audio should not make a difference. Please show your script that trims the leading audio based on the silence effect. > Using the 1kHz tones as a marker will give me a more accurate edit point. > Is there something in the Sox arsenal which can detect this tone? I don't think this can be done on the command line with sox the binary; perhaps with libsox, programaticaly. But perhaps you could use the pips as the silence/nonsilence cutting point - surely the pips are at very regular intervals.
