COMPUTER ANALYSIS AND SYNTHESIS OF AN ACOUSTIC PIANO NOTE

Date Issued:
1987
Summary:
An IBM Personal Computer AT system was used in conjunction with a professional data acquisition unit to digitize and store several cassette deck recorded piano notes. These digitized notes were then visually analyzed both with an AT monitor and a high resolution plotter. Fourier and Walsh Transformations were then performed on the digitized data to yield further visual information. Upon completion of this visual study, several types of data reduction and waveform synthesis methods were formulated. These experimental methods tested included a wide range of signal processing techniques such as Fourier Transformation, Walsh Transformation, Polynomial Curve Fitting, linear Interpolation, Amplitude Normalization, and Frequency Normalization. The actual test performed on the experimental synthesis method consisted of recreating the piano note and then subjectively comparing the audio performance of the synthetic note versus the original note.
