SYNOPSIS

sframp [-u n][-d n][-o outputSoundfile] inputSoundfile

DESCRIPTION

sframp creates and S-shaped ramp at the beginning and/or ending of a soundfile, where the amplitudes are ramped from 0-1 at the beginning and 1-0 at the end.

OPTIONS

−u n

Upramp (initial) length. Default value for I. n is 500 samples.

−d n

Downramp (final) length. Default value for n is 500 samples.

−o outputSoundfile

Where to write the newly-ramped soundfile. The default output soundfile is sframpOut.wav .

USAGE

sframp -d 10 soundfile

Apply a "down" ramp to the soundfile at the end, and write the output to the default soundfile sframpOut.wav .

sframp -o out.wav inputSoundfile.aiff

Apply the default ramps (500 samples up and 500 samples down) to inputSoundfile.aiff and place the output in out.wav .
