manpage.1'. You may view the manual page with: `docbook-to-man manpage.sgml | nroff -man | less'. A typical entry in a Makefile or Makefile.am is: manpage.1: manpage.sgml docbook-to-man $< > $@ The docbook-to-man binary is found in the docbook-to-man package. Please remember that if you create the nroff version in one of the debian/rules file targets (such as build), you will need to include docbook-to-man in your Build-Depends control field. --> Paul"> Brossier"> December 1, 2004"> 1"> piem@aubio.org"> AUBIONOTES"> Debian"> GNU"> GPL"> ]>

&dhfirstname; &dhsurname; 2003 &dhusername; &dhdate; &dhucpackage; &dhsection; &dhpackage; a command line tool for real time extraction of musical notes. &dhpackage; [options] [-i soundfile] &dhpackage; attempts to detect notes in audio signals, segmenting consecutive events using onset detection, and determining their pitch using a fundamental frequency extraction algorithm. When started without an input file argument (--input), &dhpackage; creates a jack input and a MIDI output. When an input file is given, the results are given on the console. 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 Run analysis on this audio file. Most common uncompressed formats are supported. -o --output fileout Save results in this file. The file will be created on the model of the input file. Results are marked by a short wood-block sample. -P --pitch mode The pitch detection function to run. Available functions are yinfft, yin, mcomb, fcomb, and schmitt. -O --onset mode The onset detection function to run. Available functions are complexdomain, hfc, phase, specdiff, energy, kl and mkl. By default, both Kullback Liebler (kl) and complex domain are used in parallel. -t --threshold value Set the threshold value for the onset peak picking. Typical values are within 0.001 and 0.900. Default is 0.1. Lower threshold values imply more onsets detected. Try 0.3 in case of over-detections. -j --jack Run in jack mode (default when started without input file) and creates a midi output. -v --verbose Show results on the console (default). -h --help Show summary of options. For now the program has only been tested on audio signals sampled at 44.1 kHz. aubioonset(1) aubiotrack(1) aubiocut(1) aubiopitch(1) This manual page was written by &dhusername; (&dhemail;).
