TESTSIG

testsig - generate some test signals

testsig (-s|-n|-p|-P|-Q|-T type) (-f freq) (-e stopfreq) (-t time) (-r time|-R time) (-d) (-S sampfreq) file

testsig is a program to generate some test signals directly into a speech file.

-I Identify program name and version number.

-s Generate a sine wave. Default.

-n Generate white noise.

-P Generate pink noise.

-p Generate pulse train.

-Q Generate silence (quiet).

-f freq Specify frequency of sine wave. Default 1000Hz.

-e endfreq Specify end frequency for chirp.

-t time Specify duration of signal. Default 0.5 seconds.

-r time Specify time to linearly ramp up amplitude to maximum at start and end. Default 0 seconds.

-R time Specify time to logarithmically ramp up amplitude to maximum at start and end. Default 0 seconds.

-d Differentiate output.

-S sampling_rate Specify the signal sampling rate. Default 20000Hz.

-T type Specify type of waveform: available: sine, pulse, pulse-train, white-noise, sawtooth, chirp, pink-noise, silence.

SP Test signal.

type= shows sine or noise waveform

freq= shows sine wave frequency

time= shows duration of signal

ramp= shows ramp time of signal

differenced shows signal has been differentiated.

samprate= shows sampling rate.
