Built with Victor Lazzarini’s PVS opcodes, that allow for real-time “streaming” phase-vocoder based analysis-resynthesis, PsychoDelay creates a complex “cloud” of unique (multiple) delays in different frequency bands.
The pvsanal opcode is used to analyze the input and generate “fsig” data using phase-vocoder based overlap-add analysis.Using the pvsbuffer opcode, a second process reads from a circular buffer, of user specified length (in seconds),taking a handle for the buffer and a time pointer that holds the current read position (also in seconds) and wraps around when reaching the end.
Multiple instances of this process, with different time positions, are resynthesized using an inverse FFT producing this spectrally shimmering result.
