A very simple crude sinewave generator.
The file required is generated inside the code, is linear interpolated and requires /dev/audio to work. Ensure you have this device, if not the download oss-compat from your OS's repository...

This is a small program as a tester for a basic sweep generator for bandwidth testing of AudioScope.sh.
This DEMO is only capable of 4KHz down to about 85Hz and back due to the low bit rate, but it is proof of concept for a much wider variant using a much higher bit rate.
The file generated... (4 Replies)

Ok guys, gals and geeks...
As from today I am starting to learn awk in earnest doing something totally different.
I am going to create a pseudo-Audio_Function Generator centred around OSX 10.11.x minimum. The code below is a tester to see what the possibilities are.

Hi all...
I intend to do an Audio Function Generator using Awk, (already started thanks to Don), but the biggest thing I have struggled with was variable frequency.
I was going to generate differing sized waveforms on the fly but that would that would mean the frequencies are dependent on any... (2 Replies)

play
play(1) General Commands Manual play(1)NAME
play - play any sound file to audio device
rec - record audio to any sound file format
SYNOPSIS
play [fopts] infile [effect]
rec [fopts] outfile [effect]
DESCRIPTION
This manual page briefly documents the play and rec commands.
play and rec are programs that allow you to play and record different types of sound files from the command line. They are front ends to
the more general sox(1) package. Normally, the play command will automatically detect the type and other parameters of the soundfile. If
it can't do so, the parameters can be changed through options.
OPTIONS
A summary of common options are included below. For a complete description of options and their values, see the sox(1) man page.
-c [channels], --channels=[channels]
Define the number of channels in the file.
-d [device], --device=[device]
Specify a different device to play the sound file to.
-f [format], --format=[format]
Specify bit format of the sample. One of s, u, U, A, a, or g.
-r [rate], --rate=[rate]
Specify the sample rate of the audio data (samples per second).
-s [size], --size=[size]
Specify the width of each sample. One of b, w, l, f, d, or D.
-t [type], --type=[type]
Specify audio file format to use. Useful if it can not be automatically determined.
-v [volume], --volume=[volume]
Change the audio volume
-x , --xinu
Reverse the byte order of the sample (only works with 16 and 32-bit data).
-h, --help
Show summary of options.
--version
Show version of play/rec.
Description of effects are described in the
sox(1) man page.
