This audio signal analysis program allows you to select any audio input device available in Mac OS X version 10.2 or later.
You can choose from all input signal formats supported by the current audio device. You can also save oscilloscope trace data or spectral data to disk for import into Matlab, Excel or Octave.
The spectrum analyzer allows you to choose from five possible frequency spans and provides linear and dB voltage scales. It also provides auto and manual scaling of the vertical voltage axis, linear and logarithmic frequency scales. The oscilloscope provides auto and manual scaling of the vertical voltage axis, triggering on positive or negative slope, and manual scaling of the horizontal time axis.
