Wave Tools 1.0 by
Paul Kellett
WaveTools is a suite of
real-time audio analysis tools for high quality measurements:
Spectrum analyzer and oscilloscope (with calibration in dB or
Volts), Signal Generator (tones plus pink and white noise) and Audio
Meter / Vectorscope. Although the program was written for Windows
3.1, it runs fine on XP as well. Features include:
- Oscilloscope - a dual-channel storage oscilloscope
- Spectrum Analyzer - a narrowband spectrum analyzer. The
display shows level (Y-axis) against frequency (X-axis)
- Audio Meter - provides stereo peak meters, stereo RMS
(average) meters, phase correlation meter, vectroscope and peak
hold.
- Signal Generator - produce test tones from 20 Hz to 20 kHz
plus white and pink noise. 1/3-octave band frequencies and musical
notes (based on A440) can be directly selected from the menu.

PC-DSP
Standard Edition from DSP Solutions
PC-DSP is an
interactive, menu-driven software package used
for
-
discrete-time
and continuous-time waveform synthesis using a variety of
methods,
-
basic signal
operations (arithmetic, nonlinear, and statistical functions),
fast Fourier transforms (forward & inverse transforms, window
functions),
-
convolution and
correlation functions,
-
solution of
difference equations,
-
analysis and
design of IIR and FIR filters,
-
digital filter
simulation and code generation,
-
power spectrum
estimation using classical and modern techniques.
It is quite simple
and straightforward to use, and yet powerful and extensible enough
to be used by practicing engineers as well as students of digital
signal processing.
