aubio 0.4.9                                       04 March 2025                                         AUBIO(1)

       The "beat" command accepts all common options and no additional options.

       The default buffer size for the beat algorithm is 1024. The default hop size is 512.

       The general syntax is "aubio <command> <soundfile> [options]". The following commands are available:

       onset  get onset times

       pitch  extract fundamental frequency

       beat   get locations of beats

       tempo  get overall tempo in bpm

       notes  get midi-like notes

       mfcc   extract mel-frequency cepstrum coefficients

       melbands
              extract mel-frequency energies per band

       For  a list of available commands, use "aubio-h". For more info about each command, use "aubio <command>
       --help".

       The following options can be used with all commands:

       <source_uri>,-i<source_uri>,--input<source_uri>
              input sound file to analyse (required)

       -r<freq>,--samplerate<freq>
              samplerate at which the file should be represented (default:  0,  e.g.  samplerate  of  the  input
              sound)

       -H<size>,--hopsize<size>
              overlap size, number of samples between two consecutive analysis (default: 256)

       -B<size>,--bufsize<size>
              buffer size, number of samples used for each analysis, (e.g. FFT length, default: 512)

       -h,--help
              show help message and exit

       -Tformat,--time-formatformat
              select time values output format (samples, ms, seconds) (default: seconds)

       -v,--verbose
              be verbose (increment verbosity by 1, default: 1)

       -q,--quiet
              be quiet (set verbosity to 0)

       Extract onsets using a minimum inter-onset interval of 30ms:

           aubio onset /path/to/input_file -M 30ms

       Extract pitch with method "mcomb" and a silence threshold of -90dB:

           aubio pitch /path/to/input_file -m mcomb -s -90.0

       Extract MFCC using the standard Slaney implementation:

           aubio mfcc /path/to/input_file -r 44100

       These options can be used before any command has been specified.

       -h,--help
              show help message and exit

       -V,--version
              show version

       The "melbands" command accepts all common options and no additional options.

       The "mfcc" command accepts all common options and no additional options.

       The following additional options can be used with the "notes" subcommand.

       -s<value>,--silence<value>
              silence threshold, in dB (default: -70)

       -d<value>,--release-drop<value>
              release drop level, in dB. If the level drops more than this amount since the last  note  started,
              the note will be turned off (default: 10).

       The following additional options can be used with the "onset" subcommand.

       -m<method>,--method<method>
              onset   novelty   function  <default|energy|hfc|complex|phase|specdiff|kl|mkl|specflux>  (default:
              default)

       -t<threshold>,--threshold<threshold>
              threshold (default: unset)

       -s<value>,--silence<value>
              silence threshold, in dB (default: -70)

       -M<value>,--minioi<value>
              minimum Inter-Onset Interval (default: 12ms)

       The following additional options can be used with the "pitch" subcommand.

       -m<method>,--method<method>
              pitch detection method <default|yinfft|yin|mcomb|fcomb|schmitt> (default: default, e.g. yinfft)

       -t<threshold>,--threshold<threshold>
              tolerance (default: unset)

       -s<value>,--silence<value>
              silence threshold, in dB (default: -70)

       The default buffer size for the beat algorithm is 2048. The default hop size is 256.

aubio [-h] [-V] <command> ...

       The "tempo" command accepts all common options and no additional options.

       The default buffer size for the beat algorithm is 1024. The default hop size is 512.
