Short: Free voice codec Author: see the docs Uploader: Diego Casorran Type: mus/misc Version: 1.0ß Requires: ixemul.library Architecture: m68k-amigaos The Speex project aims to build an open-source patent-free voice codec. Unlike other codecs like MP3 and Ogg Vorbis, Speex is specially designed for compressing voice at low bit-rates for applications such as voice over IP (VoIP). In some sense, it is meant to be complementary to the Ogg Vorbis codec. Although we aim at providing a patent-free codec, we strongly suggest you have a look at patent issues if you are thinking about using Speex commercially. The speech coding field is a real patent minefield and the scope and enforceability of all these patents is sometimes unclear, not to mention that each country has different laws. To use Speex: % speexenc [-n or -w] input_file.sw compressed_file.spx % speexdec compressed_file.spx output_file.sw where -n is for narrowband (8 kHz sampling) and -w is wideband (16 kHz sampling). All audio files are assumed to be raw (no header) 16-bit PCM files. To convert a .wav file into this format: % sox my_file.wav -t sw my_file.sw Note that if the original sampling frequency of the wav is not 8 kHz or 16 kHz, you will need to add "-r 8000" or "-r 16000" (without the quotes). To create a .wav file: % sox -t sw my_file.sw my_file.wav ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°` `°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø Latest update of this package can be found at http://amiga.sourceforge.net/ ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°`ø°` `°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø`°ø ·············································A·r·c·h·i·v·e··C·o·n·t·e·n·t·s·· LhA Freeware Version 2.2 Copyright © 1991-94 by Stefan Boberg.
