Ztx-based pitch detection and pitchshift TEXT_HERE Cycling '74 TEXT_HERE original signal TEXT_HERE pitch (Hz) TEXT_HERE detune modulation (Cents) TEXT_HERE retuned signal The retuned output signal. detected frequency The detected frequency. closest note The closest note detected. deviation in cents The deviation in cents from the closest note detected. closest note and deviation in cents A list composed of the closest note and the deviation in cents from the closest note detected. Standard pitch Reference tuning in Hz, the default is 440 Hz. Enable/disable notes in scale via MIDI notes MIDI notes as list e.g. “60 100” and “60 0” to enable/disable notes in the current notelist. If the default 12 tone chromatic scale is active, sending the note C3 (60) will enable note 0 (60 modulo 12), which is C. Reset to default tuning Go back to the default 12 note chromatic tuning. Clear current notelist The flush message is used in conjunction with sending MIDI notes and will re-enable all notes in a scale. Report current latency Report the latency in samples introduced by the retune~ object out the rightmost outlet. Specify pitch or detune modulation Signal values in the second or third inlets are used to lock the retuned signal to a specific pitch (Hz) (inlet 2) or to de fine detune modulation (inlet 3) values (Cents). Correction Ambience Threshold Set the automatic bypass when the signal contains too much noise or background ambience (reverb). A value between 0.2 and 0.4 is usually a good starting point. Range: (-10...10). Correction Amount Set the amount of pitch correction. 0 means no correction, 100 means full correction. Correction Autobypass Threshold Define the sibilance threshold at which the original signal is passed through unaffected. This bypass switch is required to make sure that sibilances in vocal recordings don’t sound too processed. A default setting of 100 is good. Correction Threshold Define the threshold at which the correction takes effect. For most applications this should be set to 0 as this will correct notes that are more that 0 cent off, wrt their ideal pitch. A setting of 10 will allow a pitch deviation of 10 cents in either direction before the correction takes effect. Enabled Notes Either the keyword “all” or a list of notes in the range from 0 to the size of the current scale minus 1 (0 .. 11 in the case of a chromatic scale) determines which notes retune will quantize to. That list may also be sent in the form of a message (e.g. enablednotes 0 2 3 5 7 9 10 ). Base note for the currently used scale.

Detect pitch Returns the average pitch of the segment that is currently being analyzed. This can be used as a pitch detector. A return value of 0.0 means that no coherent pitch could be estimated. You should expect an output fundamental frequency in the range of 50 Hz to 1000 Hz. Please note that this feature is experimental and might produce unpredictable results. In particular, it might introduce octave errors for the measured pitch depending on the input signal. Output as a signal from the second outlet. Retune Quality Sets the relative quality for retuning operations.
Basic quality for retuning calculations (the default) TEXT_HERE Good quality for retuning calculations TEXT_HERE Better quality for retuning calculations TEXT_HERE Highest quality for retuning calculations TEXT_HERE Report latency Enable (1) or disable (0) sending latency information out the right outlet of the retune~ object. Latency is reported in samples. Turn on retune Enable (1) or disable (0) retuning. Use 16-bit processing Enable (1) or disable (0) 16-bit processing. Better CPU performance can be obtained by using 16-bit processing, and it is reccomended if you are using the object for pitch detection and not retuning. Windowsize Specifies the window size to be used for retuning calculations. The range is between 16 samples and the currently used signal vector size.
