  • sonogram. Sonogram is an in many forms configurable sound analysis tool. It analyses sound and speech signals with the methods of the "Fourier Tranformation" (FFT), "Linear Prediction Analyse" (LPC), "Cepstrum Analyse", Autocorrelation and the "Wavelet transformation". It was able to open the most common audio and video file formats and is written in Java2, so it should run on any platform where Java2 is available. Sonograms main goal is to be a little speech recognizer, which will be perhaps implemented next time. Screen shots [1] [2] [3] Christoph Lauer Sonogram is free for non commercial and research purposes. Where I found some of these. It also includes MIDI programs, but we are not using midi..
