Topic: Oscilloscope. E1.
All D major! )
Suddenly it became interesting to know what is the difference of the synthesized sound from the living. I compared notes waveform E1. In E1 single string and no unnecessary interactions. I used the sound recording ("Pianowave Steinway B Samples") and Pianoteq Model B. The picture shows the grand piano sound on top, bottom - Pianoteq.
You may notice that the sound of the piano is more spacious. Sound Pianoteq contains a lot of "extra" vibrations. Either frequency no properly synchronized. It hears a rumor: the timbre of sounding splits into separate sounds in a long sound. It was interesting to hear some overtones compared in greater detail. I recorded a video comparison with the use of an oscilloscope. The height and disharmony corrected using Tuner Entropy. It was necessary to use a strong compression in order to be able to see more length of the sound. At the beginning of the sample is playing, then - Pianoteq. (When recording is often my computer slows down and the image twitches.)
You may notice that the piano is present in some power or reacting a certain way shifts the phase in the overtone (frequency of the sound wavers). This can be seen by comparing the sound of several harmonics simultaneously. More noticeable with the lower overtones(toward the end of the video). At the height of the piano harmonics exhibit interaction with each other. In Pianoteq they sound on flat frequencies throughout the sound. There are some unrecorded in the interaction model. Not enough unifying force (the force that is magnetized phase to each other). The force that stirs frequency overtones, and combines the phases in a certain way. The overtones of the band's sound can be heard, which is manifested in a lower rate of timbre living instrument (the sound you can hear overtones manifestation of lower overtones), in Pianoteq in timbre appear higher overtones (the sound you can hear overtones manifestation of higher harmonics). Maybe somewhere in the formula confused character. At the end of the video waveform is vaguely reminiscent of the planets or the oscillation of electrons around the nucleus. Perhaps the description of the sound the piano is similar to the calculation of the orbits of the planets some star system). Overall impressive how much everything else is identical in comparison to the piano. This is amazing!
