Signal Inspector is an audio tool that provides a number of signal generation and analysis tools with simple interfaces.
The application uses either the built-in audio hardware or external USB sound cards and supports most sample rates and resolutions.
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. Also noise generator (currently limited to white noise) and pulse generator with control for rise and fall time is provided.
