SPEEXENC(1)
NAME
speexenc - The reference implementation speex encoder.
SYNOPSIS
speexenc [options] input_file output_file
DESCRIPTION
- Encodes input_file using Speex. It can read the WAV or raw files.
- input_file can be:
- filename.wav
wav file
- filename.*
Raw PCM file (any extension other than .wav)
- - stdin
- output_file can be:
- filename.spx
Speex file
- - stdout
