A summary of options is included below. +.TP +.B +\fB-i\fP, \fB--input\fP \fIsource\fP +Run analysis on this audio file. Most uncompressed and +compressed are supported, depending on how aubio was built. +.TP +.B +\fB-r\fP, \fB--samplerate\fP \fIrate\fP +Fetch the input \fIsource\fP, resampled at the given +sampling \fIrate\fP. The \fIrate\fP should be specified in Hertz as an integer. If 0, +the sampling \fIrate\fP of the original \fIsource\fP will be used. Defaults to 0. +.TP +.B +\fB-B\fP, \fB--bufsize\fP \fIwin\fP +The size of the buffer to analyze, that is the length +of the window used for spectral and temporal computations. Defaults to 512. +.TP +.B +\fB-H\fP, \fB--hopsize\fP \fIhop\fP +The number of samples between two consecutive analysis. +Defaults to 256. +.TP +.B +\fB-O\fP, \fB--onset\fP \fImethod\fP +The onset detection \fImethod\fP to use. See ONSET METHODS +below. Defaults to 'default'. +.TP +.B +\fB-t\fP, \fB--onset-threshold\fP \fIthres\fP +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. +.TP +.B +\fB-M\fP, \fB--minioi\fP value +Set the minimum inter-onset interval, in seconds, the +shortest interval between two consecutive notes. Defaults to 0.030 +.TP +.B +\fB-p\fP, \fB--pitch\fP \fImethod\fP +The pitch detection \fImethod\fP to use. See PITCH METHODS +below. Defaults to 'default'. +.TP +.B +\fB-u\fP, \fB--pitch\fP-\fIunit\fP \fIunit\fP +The \fIunit\fP to be used to print frequencies. Possible +values include midi, bin, cent, and Hz. Defaults to 'Hz'. +.TP +.B +\fB-l\fP, \fB--pitch-tolerance\fP \fIthres\fP +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. +.TP +.B +\fB-s\fP, \fB--silence\fP \fIsil\fP +Set the silence threshold, in dB, under which the pitch +will not be detected. A value of \fB-20.0\fP would eliminate most onsets but the +loudest ones. A value of \fB-90.0\fP would select all onsets. Defaults to \fB-90.0\fP. +.TP +.B +\fB-d\fP, \fB--release\fP-\fIdrop\fP +Set the release \fIdrop\fP 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. +.TP +.B +\fB-T\fP, \fB--timeformat\fP format +Set time format (samples, ms, seconds). Defaults to +seconds. +.TP +.B +\fB-j\fP, \fB--jack\fP +Use Jack input/output. You will need a Jack connection +controller to feed aubio some signal and listen to its output. +.TP +.B +\fB-h\fP, \fB--help\fP +Print a short help message and exit. +.TP +.B +\fB-v\fP, \fB--verbose\fP +Be verbose. +.SH ONSET METHODS + +Available methods: default, energy, hfc, complex, phase, specdiff, kl, mkl, +specflux. +.PP +See \fBaubioonset\fP(1) for details about these methods. +.SH PITCH METHODS + +Available methods: default, schmitt, fcomb, mcomb, specacf, yin, yinfft, +yinfast. +.PP +See \fBaubiopitch\fP(1) for details about these methods. +.SH SEE ALSO + +\fBaubioonset\fP(1), +\fBaubiopitch\fP(1), +\fBaubiotrack\fP(1), +\fBaubioquiet\fP(1), +\fBaubiomfcc\fP(1), +and +\fBaubiocut\fP(1). +.SH AUTHOR + +This manual page was written by Paul Brossier <piem@aubio.org>.
