FAQ & Troubleshooting
Spectrum Analyzer and Keyboard
   
When Wave In is turned on, Spectrum Analyzer window depicts spectrum of current input sound in real-time, as is shown here:



Otherwise, it indicates Wave input device state (Stopped or Error).



Spectrum window consists of 87 bars, each corresponds to particular frequency, that is one of standard note frequencies. Each peak on the scale corresponds to the intensity of sound on this frequency. TS-AudioToMIDI transforms sound to spectrogram by means of set of oscillatory circuits (named "sensors"), each tuned to particular resonance frequency corresponding to one of standard note frequencies. Each key of piano fingerboard located under Spectrum window is the bottom for corresponding spectrogram component. You can play the note by pressing left mouse button on the key.
