Editor: Signal Inspector is a Mac OS X application that was created to suit my needs when doing some audio electronics work. It consists of a number of signal generation and analysis tools with simple interfaces.
Included tools are:
* Spectrum analyzer with variable size FFT.
* Spectrogram (waterfall) with selectable dynamic range.
* Oscilloscope with one channel and basic Trigger capability.
* Level monitor with peak and average readings.
* Tone Generator with sine, square, triangle, and sawtooth waveforms.
* Noise generator (currently limited to white noise)
* Pulse generator with control for rise and fall time.
The application uses either the built-in audio hardware or external USB sound cards and supports most sample rates and resolutions.
