sframp − Ramps the beginning and/or ending of a soundfile. |
|
sframp [-u n][-d n][-o outputSoundfile] inputSoundfile |
|
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. |
|
−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 . |
|
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 . |
|
This program will only work with WAVE, AIFF, AIFC, and the old NeXT/Sun "snd" format soundfiles, that are 16-bit PCM encoded, with 1 or 2 channels. |
