NAME
  aubioonset - a command line tool to extract musical onset times

SYNOPSIS

  aubioonset source
  aubioonset [[-i] source] [-o sink]
             [-r rate] [-B win] [-H hop]
             [-O method] [-t thres]

             [-j] [-N miditap-note] [-V miditap-velo]
             [-v] [-h]

DESCRIPTION

  aubioonset attempts to detect onset times, the beginning of discrete sound
  events, in audio signals.

  When started with an input source (-i/--input), the detected onset times are
  given on the console, in seconds.

  When started without an input source, or with the jack option (-j/--jack),
  aubioonset 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.

  -o, --output sink  Save results in this file. The file will be created on
  the model of the input file. Onset times are marked by a short wood-block
  like sound.

  -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.

  shortest interval between two consecutive onsets. Defaults to 0.020

  -s, --silence sil  Set the silence threshold, in dB, under which the onset
  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.

  seconds.

  -m, --mix-input  Mix source signal to the output signal before writing to
  sink.

  -f, --force-overwrite  Overwrite output file if it already exists.

  -j, --jack  Use Jack input/output. You will need a Jack connection

  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 onset
  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.

PITCH METHODS

  Available methods are:

  default  use the default method

  Currently, the default method is set to yinfft.

  schmitt  Schmitt trigger

  This pitch extraction method implements a Schmitt trigger to estimate the
  period of a signal. It is computationally very inexpensive, but also very
  sensitive to noise.

  fcomb  a fast harmonic comb filter

  This pitch extraction method implements a fast harmonic comb filter to
  determine the fundamental frequency of a harmonic sound.

  mcomb  multiple-comb filter

  This fundamental frequency estimation algorithm implements spectral
  flattening, multi-comb filtering and peak histogramming.

  specacf  Spectral auto-correlation function

  yin  YIN algorithm

  This algorithm was developed by A. de Cheveigne and H. Kawahara and
  was first published in:

  De Cheveigné, A., Kawahara, H. (2002) "YIN, a fundamental frequency
  estimator for speech and music", J. Acoust. Soc. Am. 111, 1917-1930.

  yinfft  Yinfft algorithm

  This algorithm was derived from the YIN algorithm. In this implementation, a
  Fourier transform is used to compute a tapered square difference function,
  which allows spectral weighting. Because the difference function is tapered,
  the selection of the period is simplified.

  Paul Brossier, Automatic annotation of musical audio for interactive systems,
  Chapter 3, Pitch Analysis, PhD thesis, Centre for Digital music, Queen Mary
  University of London, London, UK, 2006.

  yinfast  YIN algorithm (accelerated)

  An optimised implementation of the YIN algorithm, yielding results identical
  to the original YIN algorithm, while reducing its computational cost from
  O(n^2) to O(n log(n)).

`aubionotes`¶

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] [-d drop]

             [-T time-format]
             [-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.

  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.

  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.

  -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, --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.

ONSET METHODS

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

  See aubioonset(1) for details about these methods.

PITCH METHODS

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

  See aubiopitch(1) for details about these methods.

`aubioquiet`¶

NAME
  aubioquiet - a command line tool to extracts quiet and loud regions from a file

SYNOPSIS

  aubioquiet source
  aubioquiet [[-i] source]
             [-r rate] [-B win] [-H hop]
             [-T time-format]
             [-s sil]
             [-v] [-h]

DESCRIPTION

  aubioquiet will print a timestamp each time it detects a new silent region or
  a new loud region in a sound file.

  When started with an input source (-i/--input), the detected timestamps are
  printed on the console, in seconds.

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.

  -s, --silence sil  Set the silence threshold, in dB, under which the pitch
  will not be detected. Defaults to -90.0.

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

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

  -v, --verbose  Be verbose.

EXAMPLE OUTPUT

  NOISY: 28.775330

  QUIET: 28.914648

aubiocut --output is used to specify a directory, not a file.
Option --bufsize is useless for aubioquiet
aubioquiet could have a jack output
Regression, re-add slicing at silences to aubiocut
aubiocut could cut on notes
aubionotes needs onset/pitch setters.
Silence was different for pitch and onset, test.
Some aubiotrack options should be disabled (minioi, threshold).
