Sound Analysis

Christoph Lauer Sonogram

Sonogram has been programmed at the German Research Center for Artificial Intelligence (Deutsches Forschungszentrum fuer Kuenstliche Intelligenz DFKI, www.dfki.de). Sonogram is an signal analyze tool to visualize different signal analyze algorithms in the frequency domain. It generates visual plots/graphs from this algorithms and has the ability to render three dimensional interactive plots of them. The following algorithms are supported: Fourier Transformation (FFT), Linear Predictive Coding (LPC), Cepstral Analyse, Wavelet Transformation, Autocorrelation, Pitch Detection. Sonograml is mostly used in speech recognition, from Sound Engineers and bird vocal researchers. Sonogram is licensed under the Academic Free License 2.1 (AFL).
