SFS/ESYNTH

Windows Tool for Harmonic Analysis & Synthesis

ESynth is a free program designed to explain the harmonic analysis and synthesis of signals. With ESynth you can create signals by adding together individual sinusoidal waveforms (sinewaves) and study the resulting waveform and spectrum. You can also perform an analysis of an input waveform, to see how a given sound can be represented in terms of a sum of sinewaves.

Download and Installation

SFS/ESYNTH is only available by anonymous FTP from:

Download the file called esynth1dd.exe into a temporary directory. Then find and run the file to unpack and install.

ESECTION - Speech signal cross-sections

ESection is a free program for calculating and displaying spectral and other related analyses of sections of a speech signal. It can be used to demonstrate the different spectral properties of elements of speech. It can also calculate an LPC spectrum, autocorrelation and cepstrum analyses, and can display the signal as a waveform or as a spectrogram. It automatically finds formant and fundamental frequency values. More information.
