If you wish to use any of these programs in a commercial setting, please contact me.

Please click here to contact me if you have any questions.

The programs are as follows: (1) a voice editor for the Yamaha SY22, SY35 and TG33 synthesisers for Windows and Atari ST; (2) a WAV File Leveller for Windows and also for Linux; (3) a WAV File Splitter for Windows.

Please feel free to download and try these programs, but if you use them please give a donation, however small, to show your appreciation. Just click on the button on the right.

• Wave File Leveller version 3.2

This version corrects an apparantly long standing bug in the measurement routine. While the "highest level" setting was working correctly, the "average level" setting was too low by 6dB. It also corrects a minor bug that prevented it from running correctly under WINE in Linux. It has been tested under version 0.9.15 of WINE.

Native Linux version below

Adjusts the level of WAV files to be the same. This program uses the average perceived levels of the files (not peak normalisation) which produces a more accurate result. It now has the ability to measure volume using a B weighted filter, which mimics the perceived volume at normal listening levels.

Run the downloaded program and it will install into your "Program Files" directory and a shortcut will be added to your start menu, called "Wave File Leveller".

New in version 3 - options to allow an external command line encoder such as LAME to be used; built-in limiting and dithering have been removed; two slots for VST effects plug-ins created instead to allow for external (better!) limiting and dithering to be used.

The program no longer has a built-in limiter, so I recommend downloading the excellent Classic Master Limiter from Kjaerhus Audio. Place the DLL from the downloaded ZIP file into the Wave File Leveller program directory; set the threshold control to 0 dB to ensure that the gain indicated by the Wave File Leveller program is the gain you get! You can search KVR Audio for other free plug-ins.

VST is a trademark of Steinberg Media Technologies GmbH

• Wave File Leveller for Linux version 1.0.1

This program is nearly identical to the Windows version except that it does not support VSTs. It has its own internal limiter (re-written from the one that the Windows version had before it went VST). You can download the source files of this version or a compiled binary. It was build under KDE Release 3.5.2

Version 1.0.1 - this corrects a very silly fault in version 1.0 that would not perform amplifications of less than 1.0x (okay, attenuations!)

• WAV file splitter version 1

This file extracts individual sound events from a WAV file. I wrote this to facilitate the extraction of sounds from sample CDs. It is a command line tool. Download the zip file and extract the executable file to C:\WINDOWS\SYSTEM32 (or equivalent) so that it is available from the command prompt without having to muck around with any environment variables.

• Windows Voice editor for Yamaha SY22, SY35 and TG33

Allows these now ageing synthesisers to be programmed completely - options from the synth front panel are very limited, with this program you can edit all the FM parameters. This is version 2.2 and has improved TG33 support.

NB: ensure that the MIDI channel set in the program is the same as the Basic Receive Channel of the synth.

• Atari ST Voice editor for Yamaha SY22 and SY35

Predecessor to the above, but for Atari ST. Old and no longer maintained, but it works. Includes source code.
