"Pictorial of Sounds,"
Time-frequency properties of tones played by musical instruments are
shown. Samples from the University of Iowa Musical Instruments Samples
(MIS) were used.
These samples were analyzed by the non-harmonic Fourier analysis (SFA).
The time resolution is 16ms and the frequency resolution 1Hz.
Original wave form data are from
