smallest array will be used, and any extra values in the other two arrays are thrown away. Bandwidths This is array is optional and need only be set if the SendBandwidths box is checked. Bandwidths are required by the FormantBankOscillator and VocoderChannelBank, but they are not required by the OscillatorBank. Enter an array of bandwidth values separated by spaces. If you leave off the units, the values will be interpreted as frequencies in hertz. Enclose any arithmetic expressions or frequencies with units within curly braces, for example: 609 {!Freq1 * 1000} {2048 hz} {60 nn} {5 c} The number of bandwidth values should be the same as the number of amplitude and frequency values. If the frequency, amplitude and bandwidth arrays are different sizes, the smallest array will be used and any extra values in the other two arrays are thrown away. 372
SyntheticSpectrumFromSounds Spectral Sources Category Generates a synthetic spectrum whose amplitudes, frequencies (and optionally, bandwidths) are controlled by two input Sounds. One input supplies the amplitudes and the other supplies the frequencies (optionally alternating with bandwidths). You can think of each cycle of the input Sounds as defining one frame of the spectrum. If the input Sounds change from cycle to cycle, then the spectrum will also change from frame to frame. A SyntheticSpectrumFromSounds (like other Sounds in the Spectral Sources category) outputs spectral envelopes in the following format: Left Channel: Amp1 Amp2 ... AmpN Right Channel: Freq1 Freq2 ... FreqN For each frame, Amp1 is the amplitude of the first partial (and Freq1 is the frequency or pitch of the first partial), Amp2 is the amplitude of the second partial (corresponding with Freq2), and AmpN is the amplitude of the highest numbered partial (specified in NbrPartials). Then the whole sequence repeats for the next frame of the spectrum. Because of this repetition rate, the output of the SyntheticSpectrumFromSound has a kind of periodicity to it, where the period is the equal to the same number of samples as there are partials in each frame. Amplitudes If the period of this Sound in samples is equal to NbrPartials, then one cycle of this Sound defines one frame’s worth of amplitudes for the synthesized spectrum. (For example, to synthesize 80 partials, set the Frequency of this Sound to 80 samp inverse if you want the cycles to line up with frames). If the repetition rate of this Sound is lined up with the number of partials in each frame of the spectrum, then the waveform of each cycle of this Sound will correspond to a kind of spectral envelope for each frame of the spectrum. For example, if you select ExponRev as the waveform of an oscillator whose period is 80 samples and set NbrPartials to 80, then each frame of the spectrum will have high amplitudes on its lower-numbered partials and lower amplitudes on the upper partials. Even more interesting is to make this Sound’s frequency adjustable within a narrow range so you can create spectral envelopes that "drift" because their repetition rates are slightly out of phase with the number of partials being generated on each frame. FrequenciesAndBandwidths If the period of this Sound in samples is equal to NbrPartials, then one cycle of this Sound defines one frame’s worth of frequencies (or pitches i f you have LogScale checked) for the synthesized spectrum. (For example, to synthesize 80 partials, set the Frequency of this Sound to 80 samp inverse if you want the cycles to line up with frames). If the repetition rate of this Sound is lined up with the number of partials in each frame of the spectrum, then the waveform of each cycle of this Sound will provide the frequencies for each partial in one frame of the spectrum. For example, if you select Ramp as the waveform of an oscillator whose period is 80 samples and set NbrPartials to 80, then, in each frame of the spectrum, the lower-numbered partials will have low frequencies, and the higher-numbered partials will have high frequencies. Even more interesting is to make this Sound’s frequency adjustable within a narrow range so you can create spectra that "drift" because their repetition rates are slightly out of phase with the number of partials being generated on each frame. If the SyntheticSpectrumFromSounds is controlling something that requires bandwidth (like FormantBankOscillator or VocoderChannelBank), and you have checked the SendBandwidths box, then 373
