20 aubionotes attempts to detect notes by looking for note onsets and
21 pitches. Consecutive events are segmented using onset detection, while
22 a fundamental frequency extraction algorithm determines their pitch.
23 When started with an input source (-i/--input), the detected notes are
25 printed on standard output, in seconds and midi note number.
26 When started without an input source, or with the jack option
28 (-j/--jack), aubionotes starts in jack mode.

31 This program follows the usual GNU command line syntax, with long
32 options starting with two dashes (--). A summary of options is included
33 below.
34 -i, --input source
36 Run analysis on this audio file. Most uncompressed and com‐
37 pressed are supported, depending on how aubio was built.
38 -r, --samplerate rate
40 Fetch the input source, resampled at the given sampling rate.
41 The rate should be specified in Hertz as an integer. If 0, the
42 sampling rate of the original source will be used. Defaults to
43 0.
44 -B, --bufsize win
46 The size of the buffer to analyze, that is the length of the
47 window used for spectral and temporal computations. Defaults to
48 512.
49 -H, --hopsize hop
51 The number of samples between two consecutive analysis.
52 Defaults to 256.
53 -O, --onset method
55 The onset detection method to use. See ONSET METHODS below.
56 Defaults to 'default'.
57 -t, --onset-threshold thres
59 Set the threshold value for the onset peak picking. Typical val‐
60 ues are typically within 0.001 and 0.900. Defaults to 0.1. Lower
61 threshold values imply more onsets detected. Try 0.5 in case of
62 over-detections. Defaults to 0.3.
63 -M, --minioi value
65 Set the minimum inter-onset interval, in seconds, the shortest
66 interval between two consecutive notes. Defaults to 0.030
67 -p, --pitch method
69 The pitch detection method to use. See PITCH METHODS below.
70 Defaults to 'default'.
71 -u, --pitch-unit unit
73 The unit to be used to print frequencies. Possible values
74 include midi, bin, cent, and Hz. Defaults to 'Hz'.
75 -l, --pitch-tolerance thres
77 Set the tolerance for the pitch detection algorithm. Typical
78 values range between 0.2 and 0.9. Pitch candidates found with a
79 confidence less than this threshold will not be selected. The
80 higher the threshold, the more confidence in the candidates.
81 Defaults to unset.
82 -s, --silence sil
84 Set the silence threshold, in dB, under which the pitch will not
85 be detected. A value of -20.0 would eliminate most onsets but
86 the loudest ones. A value of -90.0 would select all onsets.
87 Defaults to -90.0.
88 -T, --timeformat format
90 Set time format (samples, ms, seconds). Defaults to seconds.
91 -j, --jack
93 Use Jack input/output. You will need a Jack connection con‐
94 troller to feed aubio some signal and listen to its output.
95 -h, --help
97 Print a short help message and exit.
98 -v, --verbose
100 Be verbose.
