There are four audio tools that I currently offer - a Sweep Generator for frequency response analysis, resonance detection etc., a weather satellite recording level meter SatLevel, a simple Tone Burst Generator and a Vector Scope for direction finding or audio phasing checks.

Software Support and Registration

The Audio Tools are currently freeware, but if you require support on the software you must register with me.  Please note that you must e-mail me directly for support.  You can register for support for SatLevel, SweepGen and VectorScope together for less than about $35.  If you like the software, or use it regularly, registering is also an easy way to say "Thank You".

A reminder that you can be on a mailing list free of charge to be automatically notified of any updates.

Full version - the Audio Test Set

There is a much more advanced version of these tools available as my Audio Test Set which includes the sweep generator with tracking spectrum analyser and oscilloscope functions.  Please visit the Audio Test Set page for more details.


SweepGen

SweepGen turns a PC into an Audio Oscillator and Sweep Generator which can be used for testing audio or educational purposes.  In conjunction with audio test instruments, you can make frequency response plots.  SweepGen uses the sound card in your PC to produce sine waves that are mathematically correct almost to CD quality, indeed it's more likely that the quality of your PC sound card will be the limiting factor rather than the code in SweepGen.

SatLevel

This program allows you set the gain or input level to a sound card to record weather satellite signals from Meteor/Resurs, NOAA or SICH/Okean satellites.

V1.1.0 uses the newer Delphi 5 runtime library.

Requirements:

 


ToneBurst

Program to generate a single sine-wave toneburst when a button is pressed.   Full source code is provided, as I see this program more as an example.  The Beeper.pas unit that is included can be used in you own code (please acknowledge copyright if you publish this code, and do so unmodified!).  Users of this component include BBC News who use it as an alert for blind users.

V1.4.0 adds Risetime/Falltime, and Amplitude properties.

Library requirements:

VectorScope

This program plots the left and right components of a stereo signal as vectors in such a way that the direction of arrival of the signal can be estimated.  This has application to direction finding, or audio phasing checks.  A screen-shot from an earlier version...
