Pitch2Midi¶
standard mode | Pitch category
Inputs¶
pitch(real) - pitch given in Hz for conversion
voiced(integer) - whether the frame is voiced or not, (0, 1)
Outputs¶
messageType(vector_string) - the output of MIDI message type, as string, {noteoff, noteon, noteoff-noteon}
midiNoteNumber(vector_real) - the output of detected MIDI note number, as integer, in range [0,127]
timeCompensation(vector_real) - time to be compensated in the messages
Parameters¶
applyTimeCompensation(bool ∈ {true, false}, default = true) :whether to apply time compensation in the timestamp of the note toggle messages.
hopSize(integer ∈ [1, ∞), default = 128) :Pitch Detection analysis hop size in samples, equivalent to I/O buffer size
midiBufferDuration(real ∈ [0.005, 0.5], default = 0.015) :duration in seconds of buffer used for voting in the note toggle detection algorithm
minFrequency(real ∈ [20, 20000], default = 60) :minimum detectable frequency
minNoteChangePeriod(real ∈ (0, 1], default = 0.03) :minimum time to wait until a note change is detected (s)
minOccurrenceRate(real ∈ [0, 1], default = 0.5) :minimum number of times a midi note has to ocur compared to total capacity
minOffsetCheckPeriod(real ∈ (0, 1], default = 0.2) :minimum time to wait until an offset is detected (s)
minOnsetCheckPeriod(real ∈ (0, 1], default = 0.075) :minimum time to wait until an onset is detected (s)
sampleRate(integer ∈ [8000, ∞), default = 44100) :Audio sample rate
transpositionAmount(integer ∈ (-69, 50), default = 0) :Apply transposition (in semitones) to the detected MIDI notes.
tuningFrequency(integer ∈ {432, 440}, default = 440) :reference tuning frequency in Hz
Description¶
This algorithm estimates the midi note ON/OFF detection from raw pitch and voiced values, using midi buffer and uncertainty checkers.
