NAME

6       speexenc - The reference implementation speex encoder.
7

SYNOPSIS

9       speexenc [options] input_file output_file
10

DESCRIPTION

12       Encodes input_file using Speex. It can read the WAV or raw files.
13
14   input_file can be:
15       filename.wav
16              wav file
17
18       filename.*
19              Raw PCM file (any extension other than .wav)
20
21       -      stdin
22
23   output_file can be:
24       filename.spx
25              Speex file
26
27       -      stdout
28
