NAME

       aubionotes - a command line tool to extract musical notes

SYNOPSIS

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

DESCRIPTION

       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.

OPTIONS

       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.

       -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.

       -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.
