sftesttone

sftesttone − Creates a test tone with user settable properties.

sftesttone creates a sine tone of a specified frequency, amplitude, duration, and channel placement.

sftesttone allows you to create a sine-tone sweep, and prompts the user for the initial and final frequencies, amplitudes, and sweep duration. The resulting glissando is then written to a file sweep.wav .

The default values 440 Hz. and 880 Hz. for the frequencies, 84 dB for the amplitude, and 1 second for the duration.

Remember to use the "-c" option when running the program, otherwise no soundfile will be created.

−a db

Amplitude in decibels. Default: 84 dB.

−f hz

Frequency in Hertz. Default: 1000 Hertz.

−d sec

Duration in seconds. Default: 30 seconds.

−o outputsoundfile

Name of the output soundfile. Default: test.wav.

−l

Left channel only.

−r

Right channel only.

−c

Flag to "create" the soundfile.

sftesttone -c

Creates a sine tone with the default values of 1000 Hz., 84 dB, 30 seconds duration, and put it in the default soundfile test.wav .

sftesttone -a 96 -f 440 -d 10 -l -o out.wav -c

Create a sine tone with an amplitude of 96 dB, frequency of 440 Hertz, a duration of 10 seconds, left-channel only, and put it in the soundfile out.wav .
