NAME
aubiocut --- a command line tool to extract onsets and tempo from sound files.SYNOPSIS
aubiocut [options] -i soundfile
DESCRIPTION
aubiocut attempts to detect onset times, the beginning of discreted sound events, or beat locations, in audio signals.
When using the --cut option, aubiocut takes an input sound file and produce small files sliced at onset locations (or silences). The slices can then be sent for example to a player, a sequencer, or a sampler.
A plotting module is available via the Gnuplot Python package.
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 filein
- input sound file
- -m --mode onset_detection_mode
- onset detection mode [default=dual] complexdomain|hfc|phase|specdiff|energy|kl|mkl|dual
- -b --beat
- detect beats and output beat locations
- -B --bufsize=BUFSIZE
- buffer size [default=512]
- -H --hopsize=HOPSIZE
- overlap size [default=256]
- -t --threshold=THRESHOLD
- onset peak picking threshold [default=0.3]
- -C --dcthreshold=DCTHRESHOLD
- onset peak picking DC component [default=1.]
- -s --silence=SILENCE
- silence threshold [default=-70]
- -M --mintol=MINIOI
- minimum inter onset interval [default=0.048s]
- -D --delay=DELAY
- number of seconds to take back [default=system] default system delay is 3*hopsize/samplerate
- -L --localmin
- use local minima after peak detection
- -c --cut
- cut input sound file at detected labels (best used with option -L)
- -d --derivate
- derivate onset detection function
- -S --silencecut
- outputs silence locations instead of onset locations
- -z --zerocross=ZEROTHRES
- zero-crossing threshold for slicing [default=0.00008]
- -f --function
- print detection function
- -q --quiet
- be quiet
- -h --help
- Show a summary of options.
- -v --verbose
- make lots of noise [default]
Plotting options
When the Python interface to Gnuplot is installed, the following additional options are available.
- -p --plot
- draw plot
- -n --no-onsets
- do not plot detected onsets, only detection functions
- -x --xsize=SIZE
- define horizontal plot size [default=1.]
- -y --ysize=SIZE
- define vertical plot size [default=1.]
- -O --outplot=OUTPLOT
- save plot to output.{ps,eps,png,svg} instead of displaying it
BUGS
For now the program has only been tested on audio signals sampled at 44.1 kHz.
