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

OPTIONS

       -n, --narrowband
              Narrowband (8 kHz) input file

       -w, --wideband
              Wideband (16 kHz) input file

       -u, --ultra-wideband "Ultra-wideband" (32 kHz) input file

       --quality n
              Encoding quality (0-10), default 8

       --bitrate n
              Encoding bit-rate (use bit-rate n or lower)

       --vbr  Enable variable bit-rate (VBR)

       --abr rate
              Enable average bit-rate (ABR) at rate bps

       --vad  Enable voice activity detection (VAD)

       --dtx  Enable file-based discontinuous transmission (DTX)

       --comp n
              Set encoding complexity (0-10), default 3

       --nframes n
              Number of frames per Ogg packet (1-10), default 1

       --comment
              Add the given string as an extra comment. This may be used multiple times

       --author
              Author of this track

       --title
              Title for this track

       -h, --help
              This help

       -v, --version
              Version information

       -V     Verbose mode (show bit-rate)

   Raw input options:
       --rate n
              Sampling rate for raw input

       --stereo
              Consider raw input as stereo

       --le   Raw input is little-endian

       --be   Raw input is big-endian

       --8bit Raw input is 8-bit unsigned

       --16bit
              Raw input is 16-bit signed

       Default raw PCM input is 16-bit, little-endian, mono
