in the tableseg, the spectral envelope becomes a dynamically changing one. By using different functions for ifn1, ifn2, etc. This can be used to make a sound gently saturated (3rd. ++chebyshev A distortion unit which uses several low-order chebyshev polynomials to add even or odd harmonic distortion. Each location in the table will be used to scale a single analysis bin. The Freesound bundle is a collection of VST/AAX/AU, Mac/Windows plugins that I have developed while teaching music programming at UCSD and CalArts. The function size used in the tableseg should be framesize/2, where framesize is the number of bins in the phase vocoder analysis file that is being used by the vpvoc. Unlike the similarly-named channel vocoder, due to the spectral analysis phase, pv is a purely digital technique. Optionally, a table specified by ifn may be used. Phase vocoding (pv) is a form of synthesis by analysis in that a digital sound file or stored buffer is analyzed and is then resynthesized by the phase vocoder. It contained soundfile convolution, phase vocoder time and pitch changing. Vpvoc is identical to pvoc except that it takes the result of a previous tableseg or tablexseg and uses the resulting function table (passed internally to the vpvoc), as an envelope over the magnitudes of the analysis data channels. Ive made most of my electronic music tools under the name SoundHack (since. For Time stretching by factor of 8 try stretching by 2 re-synthesis and. For higher factors try with composite factor implementation. Implements soundfile convolution, a phase vocoder, a binaural filter and an. The spectral extraction and amplitude gating (new in Csound version 3.56) were added by Richard Karpen based on functions in SoundHack by Tom Erbe. Phase vocoder works best for smaller scaling factors. MAC SOUND CONVERSION PROGRAMS SoundHack Tom Erbe, Can. It is based in part on the system of Mark Dolson, but the pre-analysis concept is new. This implementation of pvoc was orignally written by Dan Ellis. Kfmod - a control-rate transposition factor: a value of 1 incurs no transposition, 1.5 transposes up a perfect fifth, and. The phase Vocoder is a wonderful tool for. These are discussed in brief, theoretical terms throughout this hypertext document. Cross-synthesis between two soundfiles with. ![]() SoundHack has many useful and interesting applications for sound manipulation and transformation. Time stretching or pitch shifting with the phase vocoder or varispeed. ktimpnt must always be positive, but can move forwards or backwards in time, be stationary or discontinuous, as a pointer into the analysis file. This glossary is designed as an exploration into the program SoundHack (.871 PPC version) written by Tom Erbe. Pitch shifting, harmonizing, time stretching, layered loops, phase mangling, ambient clouds, resonant stuttering and more. Heres what Soundhacks Tom Erbe told us: 'Pvoc Kit is a four-plugin bundle exploring the classic Phase Vocoder and Granular Synthesis algorithms. Ktimpnt - The passage of time, in seconds, through the analysis file. Pvoc Kit features time, pitch and phase: stretching, shifting and smearing.
