Publisher's Description
From Christoph Lauer:
Sonogram has been programmed at the German Research Center for Artificial Intelligence, and it is a tool to analyze speech and sound signals with methods of the:
- fast Fourier transformation (fft)
- linear predictive coding (lpc)
- wavelet transformation
- auto correlation
- pitch detection. The tool is mostly used in speech recognition, from sound engineers and bird vocal researchers.
What's new in this version: Added a welcome screen with basic instructions, a floating information window in the main sonogram. The logarithm frequency-scale was rewritten. The whole GUI was over-worked.
