ADINREC(1)							    ADINREC(1)

NAME
	   adinrec
	  - record audio device	and save one utterance to a file

SYNOPSIS
       adinrec [options...] {filename}

DESCRIPTION
       adinrec opens an	audio stream, detects an utterance input and store it
       to a specified file. The	utterance detection is done by level and
       zero-cross thresholds. Default input device is microphone, but other
       audio input source, including Julius A/D-in plugin, can be used by
       using "-input" option.

       The audio format	is 16 bit, 1 channel, in Microsoft WAV format. If the
       given filename already exists, it will be overridden.

       If filename is "-" , the	captured data will be streamed into standard
       out, with no header (raw	format).

OPTIONS
       adinrec uses JuliusLib and adopts Julius	options. Below is a list of
       valid options.

   adinrec specific options
	-freq  Hz
	  Set sampling rate in Hz. (default: 16,000)

	-raw
	  Output in raw	file format.

   JuliusLib options
	-input	{mic|rawfile|adinnet|stdin|netaudio|esd|alsa|oss}
	  Choose speech	input source. Specify 'file' or	'rawfile' for waveform
	  file.	On file	input, users will be prompted to enter the file	name
	  from stdin.

	  'mic'	is to get audio	input from a default live microphone device,
	  and 'adinnet'	means receiving	waveform data via tcpip	network	from
	  an adinnet client. 'netaudio'	is from	DatLink/NetAudio input,	and
	  'stdin' means	data input from	standard input.

	  At Linux, you	can choose API at run time by specifying alsa, oss and
	  esd.

	-lv  thres
	  Level	threshold for speech input detection. Values should be in
	  range	from 0 to 32767. (default: 2000)

	-zc  thres
	  Zero crossing	threshold per second. Only input that goes over	the
	  level	threshold (-lv)	will be	counted. (default: 60)

	-headmargin  msec
	  Silence margin at the	start of speech	segment	in milliseconds.
	  (default: 300)

	-tailmargin  msec
	  Silence margin at the	end of speech segment in milliseconds.
	  (default: 400)

	-zmean
	  This option enables DC offset	removal.

	-smpFreq  Hz
	  Set sampling rate in Hz. (default: 16,000)

	-48
	  Record input with 48kHz sampling, and	down-sample it to 16kHz
	  on-the-fly. This option is valid for 16kHz model only. The
	  down-sampling	routine	was ported from	sptk. (Rev. 4.0)

	-NA  devicename
	  Host name for	DatLink	server input (-input netaudio).

	-adport	 port_number
	  With -input adinnet, specify adinnet port number to listen.
	  (default: 5530)

	-nostrip
	  Julius by default removes successive zero samples in input speech
	  data.	This option stop it.

	-C  jconffile
	  Load a jconf file at here. The content of the	jconffile will be
	  expanded at this point.

	-plugindir  dirlist
	  Specify which	directories to load plugin. If several direcotries
	  exist, specify them by colon-separated list.

ENVIRONMENT VARIABLES
	ALSADEV
	  Device name string for ALSA. (default: "default")

	AUDIODEV
	  Device name string for OSS. (default:	"/dev/dsp")

	LATENCY_MSEC
	  Input	latency	of microphone input in milliseconds. Smaller value
	  will shorten latency but sometimes make process unstable. Default
	  value	will depend on the running OS.
