Converts signal to spectrum.

Converts spectrum to signal.

Applies a transformation to the spectrum of the signal.

Scales all frequencies. Usefull for transposition. For example, we can transpose a signal by the given amount of semitones:

scaleSpec (semitone 1) asig

Adds given amount of Hz to all frequencies.

addSpec hz asig

Scales frequency in semitones.

Settings for cross filtering algorithm.

They are the defaults for opvodes: pvsifd, tradsyn, trcross and partials.

• Fft size degree -- it's the power of 2. The default is 12.
• Hop size degree -- it's the power of 2. The default is 9
• scale --amplitude scaling factor. default is 1
• pitch -- the pitch scaling factor. default is 1
• maxTracks -- max number of tracks in resynthesis (tradsyn) and analysis (partials).
• winType -- O: Hamming, 1: Hanning (default)
• Search -- search interval length. The default is 1.05
• Depth -- depth of the effect
• Thresh -- analysis threshold. Tracks below ktresh*max_magnitude will be discarded (1 > ktresh >= 0).The default is 0.01
• MinPoints -- minimum number of time points for a detected peak to make a track (1 is the minimum).
• MaxGap -- maximum gap between time-points for track continuation (> 0). Tracks that have no continuation after kmaxgap will be discarded.

Filters the partials of the second signal with partials of the first signal.

Substitutes the partials of the second signal with partials of the first signal.
