Digital Signal Generator

Introduction

A digital audio signal generator and audio analyser

Details

Digital Signal Generator is a 16-bit digital audio generator suitable for recording onto Digital Audio CDs, or outputting on the audio output sockets of Risc OS computers.

The signals themselves are of the highest precision, mathematically
generated and can be used to test the accuracy of and calibrate audio
instrumentation, HiFi, computer audio, etc. The program can also be used as
a teaching aid to show various signal processings in action.

2 dozen different waveforms, innumerable spot frequencies, frequency sweeps, innumerable amplitudes and several different Sampling Rates can be set.

The Modulator section caters for all sorts of different modulations.

Optimal Dither can be applied to all waveforms.

The Measurement section can measure the result from the Generator, or display the results from a WAV file. Thus this generator can be used to measure the performance of computer ADC cards, HiFi CD players, and produce test signals for innumerable audio applications.

A comprehensive Measurement section: FFT 512-point FFT to 131072-point FFTs.
enables precise measurements on its waveforms, and imported waveforms.

There is also an oscillogram display showing all applicable waveforms.

If you are writing programs for audio or sound, or developing ADC/DAC card
for computers, then this program is an indispensible aid that will enable
you to spot any audio idiosyncrasies with ease.
