trlowest
Extracts the lowest-frequency track from a streaming track input signal.
The trlowest opcode takes an input containg TRACKS pv streaming signals (as generated, for instance by partials) and outputs only the lowest track. In addition it outputs two k-rate signals, corresponding to the frequency and amplitude of the lowest track signal.
Syntax
Performance
fsig -- output pv stream in TRACKS format
kfr -- frequency (in Hz) of the lowest-frequency track
kamp -- amplitude of the lowest-frequency track
fin -- input pv stream in TRACKS format.
kscal -- amplitude scaling of output.
Examples
Here is an example of the trlowest opcode. It uses the file trlowest.csd.
The example above shows partial tracking of an ifd-analysis signal, extraction of the lowest frequency and resynthesis.
