aubio 0.4.9                                       04 March 2025                                    AUBIONOTES(1)

aubionotes  attempts  to  detect  notes  by  looking for note onsets and pitches.  Consecutive events are
       segmented using onset detection, while a fundamental  frequency  extraction  algorithm  determines  their
       pitch.

       When  started  with  an  input source (-i/--input), the detected notes are printed on standard output, in
       seconds and midi note number.

       When started without an input source, or with the jack option  (-j/--jack),  aubionotes  starts  in  jack
       mode.

aubionotes - a command line tool to extract musical notes

       Available methods: default, energy, hfc, complex, phase, specdiff, kl, mkl, specflux.

       See aubioonset(1) for details about these methods.

       This  program follows the usual GNU command line syntax, with long options starting with two dashes (--).
       A summary of options is included below.

       -i,--inputsource
              Run analysis on this audio file. Most uncompressed and compressed are supported, depending on  how
              aubio was built.

       -r,--sampleraterate
              Fetch  the  input  source,  resampled  at the given sampling rate. The rate should be specified in
              Hertz as an integer. If 0, the sampling rate of the original source will be used. Defaults to 0.

       -B,--bufsizewin
              The size of the buffer to analyze, that is the length of the window used for spectral and temporal
              computations. Defaults to 512.

       -H,--hopsizehop
              The number of samples between two consecutive analysis.  Defaults to 256.

       -O,--onsetmethod
              The onset detection method to use. See ONSET METHODS below. Defaults to 'default'.

       -t,--onset-thresholdthres
              Set the threshold value for the onset peak picking. Typical values are typically within 0.001  and
              0.900.  Defaults  to  0.1.  Lower  threshold values imply more onsets detected. Try 0.5 in case of
              over-detections. Defaults to 0.3.

       -M,--minioivalue
              Set the minimum inter-onset interval, in seconds, the shortest interval  between  two  consecutive
              notes. Defaults to 0.030

       -p,--pitchmethod
              The pitch detection method to use. See PITCH METHODS below. Defaults to 'default'.

       -u,--pitch-unitunit
              The  unit  to  be  used  to  print  frequencies.  Possible values include midi, bin, cent, and Hz.
              Defaults to 'Hz'.

       -l,--pitch-tolerancethres
              Set the tolerance for the pitch detection algorithm. Typical values range  between  0.2  and  0.9.
              Pitch candidates found with a confidence less than this threshold will not be selected. The higher
              the threshold, the more confidence in the candidates. Defaults to unset.

       -s,--silencesil
              Set  the  silence  threshold,  in dB, under which the pitch will not be detected. A value of -20.0
              would eliminate most onsets but the loudest ones. A  value  of  -90.0  would  select  all  onsets.
              Defaults to -90.0.

       -d,--release-drop
              Set  the  release  drop  threshold, in dB. If the level drops more than this amount since the last
              note started, the note will be turned off. Defaults to 10.

       -T,--timeformatformat
              Set time format (samples, ms, seconds). Defaults to seconds.

       -j,--jack
              Use Jack input/output. You will need a Jack connection controller to feed aubio  some  signal  and
              listen to its output.

       -h,--help
              Print a short help message and exit.

       -v,--verbose
              Be verbose.

       Available methods: default, schmitt, fcomb, mcomb, specacf, yin, yinfft, yinfast.
