EDINBURGH SPEECH TOOLS LIBRARY VERSION 1.0.1 15th September 1997 Principal authors: Paul Taylor, Alan W Black, Simon King and Richard Caley Centre for Speech Technology University of Edinburgh 80 South Bridge Edinburgh EH1 1HN, UK http://www.cstr.ed.ac.uk/projects/speechtools.html --------------------------------------------------------- Na_play is a program for playing back sound files of vari- ous formats. At present it uses either NCD netaudio or the CSTR AO audio server protocols, and for the time being is only useable if you are running one of these as your audio server. The choice of protocol can be specified on the command line (using -p) or by setting the environment variable NA_PLAY_PROTOCOL. The main point of writing na_play is to have a single, efficient playback program which will play back files in every situation. Please feel free to suggest additions which would make na_play more useable. na_play can handle multi-channel data, different sampling rates, and byte-order conversion. The sampling rate of the file is given in the header (or on the command line for headerless data). If this does not match one of the values supported by the server, netaudio automatically re-samples the data. na_play can read from standard input. na_play can be used with xwaves by specifying play_prog na_play in your .wave_pro file. ======================================================================== Edinburgh Speech Tools Library version 1.0.1 Centre for Speech Technology Research University of Edinburgh, UK Copyright (c) 1994-1997 All Rights Reserved.
