LiveSpectralAnalysis
Tracking Live Input Category
This Sound should be used as the Spectrum parameter of an OscillatorBank. It analyzes the Input and
produces amplitude and frequency envelopes for controlling a bank of oscillators.
Input
The output of the LiveSpectralAnalysis is the spectrum of this Input.
LowestAnalyzedFreq
Check the highest frequency that will still lie below the lowest fundamental frequency of the Input. The
lower this frequency, the more time-smearing and delay, so pick the highest one that will still encompass
the fundamental.
The frequency value you select will also determine how many bandpass filters are used in the analysis
and, therefore, the number of tracks or partials generated by the analysis. The lower the frequency, the
more partials that are generated:
1 F: 512
2 F: 256
3 F: 128
4 F: 64
5 F: 32
If you use this LiveSpectralAnalysis to control an OscillatorBank, this is the maximum number of
oscillators that you should specify in the OscillatorBank (you can specify fewer of them, but specifying
more of them will not result in any additional partials).
AmpScale
This is the overall amplitude level for all the partials.
FreqScale
This scales the frequency of all the oscillators without affecting the timing or duration of the amplitude
envelopes. There is no limit on the range, so to control it continuously use:
!Freq * 10
Or to control it from a MIDI keyboard use:
!KeyNumber nn hz / 60 nn hz
Response
This is the time response of the filters. Experiment to find the best time response that does not add
distortion to the sound. This specifies the bandwidth of the bandpass filters used in the analysis:
"BestFreq" is the narrowest bandwidth, "BestTime" is the widest bandwidth, and the others are
intermediate bandwidths.
Harmonic
Some kinds of live morphs work better with Harmonic checked, but you should experiment with it both
checked and unchecked. It is a little trickier to do the harmonic analysis, so you should avoid checking
this box except in situations where it is required.
