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.
