Hi Don...

(Apologies for any typos.)

Cool.

Many thanks for your comments, it will keep me occupied for a while. ;o)

As for the keyboard() this will be a COMMAND function to change many factors of the code as it evolves much like AudioScope, (I am still slowly working on AudioScope BTW).

I will steal your code once I have gotten my head around it as this is my first reall attempt at awk to create a working app' that interests me. I have only been doing it since yesterday although I have used awk for very small code snippets inside my shell scripts. Again as with UNIX shell scripting this is a steep learning curve for me...

The script size could again approach that of AudioScope who knows. At the moment my attempt is proof of concept. I need to create SINE, SQUARE, SAWTOOTH+, SAWTOOTH-, TRIANGLE, PULSE+, PULSE-, ARBTRARY, and NOISE waveforms first and test. So this will be the next upload...

One good thing is that in uncalibrated output level format no external HW needs to be built except a test lead...

However many thanks, as usual you always respond with useful info along with others on here.

Problems with audio recording in Audacity 2.0.5. Slackware64 14.1; Intel HD Audio.

I'm trying to record audio using Audacity 2.0.5 installed from SlackBuilds. My system is 64-bit Slackware 14.1 and a sound card is Intel HD Audio. I didn't change my sound system to OSS. (Default sound system in Slackware 14.1 is ALSA, isn't it?) First, I set Internal Microphone slider in KMix...

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...

Hi all... Well I have not been inactive but working out how to make OSX 10.14.x command line audio player have a variable sample rate. This is a back door as afplay does not have a sample rate flag unlike aplay for ALSA, in Linux flavours. This is a DEMO only but a derivative of it will...

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
