NAME

Audio::AMR::Decode - Perl extension do decode .amr files

SYNOPSIS

use Audio::AMR::Decode;
Audio::AMR::Decode::amr2raw('infile.amr', 'outfile.pcm');

DESCRIPTION

This module will attempt to decode an amr encoded audio file to a raw pcm audio encoded file.

The package contains C-source files for the optimized fixed-point speech decoder. The optimized fixed-point speech decoder is bit-exact with 3GPP TS 26.073 fixed-point speech decoder version 4.1.0.

CAVEATS

Technically this works but I wouldn't call this code 'mature'. Proceed with caution
