|Code Listing by Barry Walker|
A Linux DEMO to show how to display a waveform using standard text mode Python.
The audio device /dev/dsp is used and must be available. Levels are set using the
standard audio mixers.
Just feed a signal of say 300Hz to 3KHz, (normal voice spectrum), using say, the
internal mic, and watch the waveform appear inside the X-Y graticule.
This method WILL be used for a program proper and may be uploaded to this...
This is a two channel version of the "Four Bit Vertical Coloured Analogue Bar Graph Generator DEMO...".
These are DUAL LED style "VU" meters in the vertical plane...
This is for standard Python 3.x.x.
PAR: as a VOLUME in READ mode using Python 1.4 onwards on Classic AMIGAs...
Many years ago Irmen de Jong ported Python to the Classic AMIGA range of
computers, (many thanks Irmen for your time in doing so). The versions were
Simple White Noise Generator Using Standard Python In Linux - noise.py
This code is a stand alone program to generate a signal, at the earphone sockets, of white noise.
It needs /dev/dsp to work; if you haven't got it then...
A kids level project to do for yourselves...
This is a Python DEMO to show the power of the sound card using Linux for
a specific usage that I need(ed). It is a kids level project that uses the
This very simple DEMO code records a few seconds of your voice from a microphone, (internal mic' on a laptop), and
replays your voice immedaiately after recording. It goes without saying that the RAW recording can be saved in
This code is a FUN program only to DEMO how to draw in a text mode Python shell.
There is an inkey() "function" extracted from a "class" recipe on this site.

..For STANDARD Python 2.6 and above...
This code will display a horizontal full colour analogue "VU" style meter. It displays green for normal, yellow
for warning and red for danger with a critical error beep near the end...
This is one of a few Arduino Python snippets to come your way. This one is DEDICATED entirely to the classic stock
AMIGA A1200HD emulation inside WinUAE. With a small hardware modification it WILL work on a genuine stock AMIGA
I needed a simple standard Python analogue and digital display along with an overload beep when used as a
Analogue readout, for quick glance.
Digital readout, for better accuracy.
Beep, to warn me of...
