For Overtone 1.15Publisher's description


Overtone is a MP3 & Audio software developed by Aegidius Plüss. After our trial and test, the software is proved to be official, secure and free. Here is the official description for Overtone:

Brothersoft Editor: Overtone is a Windows application for physics courses, designed to make experiments and demonstrations in the fields of acoustics, oscillations and musical instruments.

In synthesizer experiments you select the amplitudes and phases of the fundamental and 9 overtones to construct the beginning of a Fourier Series. The sum is seen on a graphics display and the signal is available as sound card output.

You can test the Helmholtz assumption that the relative phases of the overtones are irrelevant to hearing.

In analyser experiments you Capture sound from the sound card or from a WAV file up to several seconds long, select the starting time of the time slice and analyse time and Frequency responses. The example shows the spectrum of a piano playing a Middle C (262 Hz). The non-harmonic overtones are clearly seen. (Due to the stiffness of the string, the frequencies of the partials are too high.)

You may filter data with a digital filter and display spectrograms in color mode. This example shows the spectrogram taken from the word "harris" in the frequency range 0..10 kHz with a 4096-point-FFT every 2 ms (post processing). The formants of "i" and the high spectral components of "s" are clearly visible.

Short time spectral information may also be displayed in a 3-D representation, called "waterfall". The following example shows the waterfall spectrum of the same word "harris" as before. The red Layer picks out the spectrum of "i" where the formants are visible again. The presentation may be rotated automatically or manually with scroll bars, in order to select the best "camera point".
