15DESCRIPTION
16
17  aubionotes attempts to detect notes by looking for note onsets and pitches.
18  Consecutive events are segmented using onset detection, while a fundamental
19  frequency extraction algorithm determines their pitch.
20
21  When started with an input source (-i/--input), the detected notes are
22  printed on standard output, in seconds and midi note number.
23
24  When started without an input source, or with the jack option (-j/--jack),
25  aubionotes starts in jack mode.
26
27OPTIONS
28
29  This program follows the usual GNU command line syntax, with long options
30  starting with two dashes (--). A summary of options is included below.
31
32  -i, --input source  Run analysis on this audio file. Most uncompressed and
33  compressed are supported, depending on how aubio was built.
34
35  -r, --samplerate rate  Fetch the input source, resampled at the given
36  sampling rate. The rate should be specified in Hertz as an integer. If 0,
37  the sampling rate of the original source will be used. Defaults to 0.
38
39  -B, --bufsize win  The size of the buffer to analyze, that is the length
40  of the window used for spectral and temporal computations. Defaults to 512.
41
42  -H, --hopsize hop  The number of samples between two consecutive analysis.
43  Defaults to 256.
44
45  -O, --onset method  The onset detection method to use. See ONSET METHODS
46  below. Defaults to 'default'.
47
48  -t, --onset-threshold thres  Set the threshold value for the onset peak
49  picking. Typical values are typically within 0.001 and 0.900. Defaults to
50  0.1. Lower threshold values imply more onsets detected. Try 0.5 in case of
51  over-detections. Defaults to 0.3.
52
53  -p, --pitch method  The pitch detection method to use. See PITCH METHODS
54  below. Defaults to 'default'.
55
56  -u, --pitch-unit unit  The unit to be used to print frequencies. Possible
57  values include midi, bin, cent, and Hz. Defaults to 'Hz'.
58
59  -l, --pitch-tolerance thres  Set the tolerance for the pitch detection
60  algorithm. Typical values range between 0.2 and 0.9. Pitch candidates found
61  with a confidence less than this threshold will not be selected. The higher
62  the threshold, the more confidence in the candidates. Defaults to unset.
63
64  -s, --silence sil  Set the silence threshold, in dB, under which the pitch
65  will not be detected. A value of -20.0 would eliminate most onsets but the
66  loudest ones. A value of -90.0 would select all onsets. Defaults to -90.0.
67
68  -T, --timeformat format  Set time format (samples, ms, seconds). Defaults to
69  seconds.
70
71  -j, --jack  Use Jack input/output. You will need a Jack connection
72  controller to feed aubio some signal and listen to its output.
73
74  -h, --help  Print a short help message and exit.
75
76  -v, --verbose  Be verbose.
77
78ONSET METHODS
79
80  Available methods: default, energy, hfc, complex, phase, specdiff, kl, mkl,
81  specflux.
82
83  See aubioonset(1) for details about these methods.
84
85PITCH METHODS
86
87  Available methods: default, schmitt, fcomb, mcomb, specacf, yin, yinfft.
88
89  See aubiopitch(1) for details about these methods.
