Application of a Real-Time Hadamard Transform Network to Sound Synthesis

Document Thumbnail

A Hadamard transform (HT) analyzes a waveform into Walsh function spectral components in the same manner that a fast Fourier transform (FTT) analyzes a waveform into sine wave components. In contrast to the FFT, a real-time HT network is easy to construct from analog components as the flow graph does not involve complex number arithmetic. The separated Walsh spectral components can be manipulated in a variety of ways before applying them to the inverse transform and time ordering the output for an audio signal.
