       aubionotes - a command line tool to extract musical notes


       aubionotes source
       aubionotes [[-i] source]
                  [-r rate] [-B win] [-H hop]
                  [-O method] [-t thres]
                  [-p method] [-u unit] [-l thres]
                  [-T time-format]
                  [-s sil]
                  [-j] [-v] [-h]


       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.


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

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

       -r, --samplerate rate
              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, --bufsize win
              The  size  of  the  buffer  to  analyze,  that is the length of the window used for
              spectral and temporal computations. Defaults to 512.

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

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

       -t, --onset-threshold thres
              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, --minioi value
              Set the minimum inter-onset interval, in seconds, the shortest interval between two
              consecutive notes. Defaults to 0.030

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

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

       -l, --pitch-tolerance thres
              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, --silence sil
              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.

       -T, --timeformat format
              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.
