sfwaves − Sums a sequence of frequencies and plays them. |
|
sfwaves [-d dur][-a amp][-t type][-o
outputSoundfile] f1 f2 f3 ... |
|
sfwaves is useful for exploring what the combination of frequencies can do. Frequencies are given in Hertz, and the generating waveform can be set on the command line, along with duration and amplitude. |
|
sfwaves 440 660 770 |
|
Sum together the frequencies 440+660+770, using default amplitude and duration, and place the output in the file sfwaveout.wav which is the default output soundfile. |
|
sfwaves -d 10 -a 20000 -t tri 440 660 770 880 990 |
|
Sum together the frequencies on the command line, use a triangle wave to create them, have the total duration be 10 seconds, and the linear amplitude be 20000. The output is again placed in sfwaveout.wav . |
|
sfwaves will only write WAVE, AIFF, or SND files, based on the file extension. |
