R.A.Swetman homepage

Welcome to R.A.Swetman's site.

Here you will find a collection of programs (old and new) suitable for Risc OS machines only.
They work on both Risc PC and ARMX6 machines (with one exception).

They are stored as 'Zip' files.
After downloading you will need to 'unzip' them, using !SparkPlug or similar.

You may find a problem running unzipped files from a RAM disc - the simple remedy is
to copy the files elsewhere before running them.

The software is divided into 8 sections : -

  Audio, Basic, Desktop, Fontutils, Graphics, Mandelbrots, Maths, Utils.

 

DOWNLOADS - just click on the icon to start the download ....

with some prolonged applause. It may also be too quiet/too loud. You may wish to edit
out the introduction and/or the ending and also alter the overall volume.
This is exactly what !EditMP3 enables you to do.
It then converts the MP3 to WAV, using the enclosed 'madplay' application.
