&dhucpackage; &dhsection; &dhpackage; a command line tool to extract onsets and tempo from sound files. &dhpackage; [options] -i soundfile DESCRIPTION &dhpackage; attempts to detect onset times, the beginning of discreted sound events, or beat locations, in audio signals. When using the option, &dhpackage; 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. input sound file onset detection mode [default=dual] complexdomain|hfc|phase|specdiff|energy|kl|mkl|dual detect beats and output beat locations buffer size [default=512] overlap size [default=256] onset peak picking threshold [default=0.3] onset peak picking DC component [default=1.] silence threshold [default=-70] minimum inter onset interval [default=0.048s] number of seconds to take back [default=system] default system delay is 3*hopsize/samplerate use local minima after peak detection cut input sound file at detected labels (best used with option -L) derivate onset detection function outputs silence locations instead of onset locations zero-crossing threshold for slicing [default=0.00008] print detection function be quiet Show a summary of options. make lots of noise [default] Plotting options When the Python interface to Gnuplot is installed, the following additional options are available. draw plot do not plot detected onsets, only detection functions define horizontal plot size [default=1.] define vertical plot size [default=1.] 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.
