sfnoise − A "white" noise generator. |
|
sfnoise [−a dB][−t type][−d seconds][-r samplingRate][-o outputSoundfile] |
|
sfnoise creates "white" noise, either "uniform" (the default) or "gaussian", at a variety of durations, amplitudes, and sampling rates. |
|
sfnoise -d 10 |
|
Generate 10 seconds of "uniform" white noise (the default), and put the output into noise.wav , which is also the default. |
|
−a dB |
Set the output amplitude level to dB decibels. |
|
−t type |
|
type can either be gaussian or uniform . |
|
−o file |
|
Place the output in file . |
|
−d n |
Create the noise for n seconds. This variable must be given by the user. |
|
−r srate |
|
Set the sampling rate to be srate . The default is 44100 samples per second. |
|
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. |
