NAME

           adintool
          - a tool to record / split / send / receive audio streams

SYNOPSIS

       adintool {-in inputdev} {-out outputdev} [options...]

DESCRIPTION

       adintool analyzes speech input, finds speech segments skipping silence, and records the
       detected segments in various ways. It performs speech detection based on zerocross number
       and power (level), and records the detected parts to files or other output devices
       sucessively.

       adintool is a upper version of adinrec with various functions. Supported input device are:
       microphone input, a speech file, standard tty input, and network socket (called adin-net
       server mode). Julius plugin can be also used. Detected speech segments will be saved to
       output devices: speech files, standard tty output, and network socket (called adin-net
       client mode). For example, you can split the incoming speech to segments and send them to
       Julius to be recognized.

       Output format is WAV, 16bit (signed short), monoral. If the file already exist, it will be
       overridden.

OPTIONS

       All Julius options can be set. Only audio input related options are treated and others are
       silently skipped. Below is a list of options.

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

        -in  inputdev
          Audio input device. "mic" to capture via microphone input, "file" for audio file input,
          and "stdin" to read raw data from standard-input. For file input, file name prompt will
          appear after startup. Use "adinnet" to make adintool as "adinnet server", receiving
          data from client via network socket. Default port number is 5530, which can be altered
          by option "-inport".

          Alternatively, input device can be set by "-input" option, in which case you can use
          plugin input.

        -out  outputdev
          Audio output device store the data. Specify "file" to save to file, in which the output
          filename should be given by "-filename". Use "stdout" to standard out. "adinnet" will
          make adintool to be an adinnet client, sending speech data to a server via tcp/ip
          socket. When using "adinnet" output, the server name to send data should be specified
          by "-server". The default port number is 5530, which can be changed by "-port" option.

        -inport  num
          When adintool becomes adinnet server to receive data (-in adinnet), set the port number
          to listen. (default: 5530)

        -server  [host] [,host...]
          When output to adinnet server (-out adinnet), set the hostname. You can send to
          multiple hosts by specifying their hostnames as comma-delimited list like
          "host1,host2,host3".

        -port  [num] [,num...]
          When adintool send a data to adinnet server (-out adinnet), set the port number to
          connect. (default: 5530) For multiple servers, specify port numbers for all servers
          like "5530,5530,5531".

        -filename  file
          When output to file (-out file), set the output filename. The actual file name will be
          as "file.0000.wav" , "file.0001.wav" and so on, where the four digit number increases
          as speech segment detected. The initial number will be set to 0 by default, which can
          be changed by "-startid" option. When using "-oneshot" option to save only the first
          segment, the input will be saved as "file".

        -startid  number
          At file output, set the initial file number. (default: 0)

        -oneshot
          Exit after the end of first speech segment.

        -nosegment
          Do not perform speech detection for input, just treat all the input as a single valid
          segment.

        -raw
          Output as RAW file (no header).

        -autopause
          When output to adinnet server, adintool enter pause state at every end of speech
          segment. It will restart when the destination adinnet server sends it a resume signal.

        -loosesync
          When output to multiple adinnet server, not to do strict synchronization for restart.
          By default, when adintool has entered pause state, it will not restart until resume
          commands are received from all servers. This option will allow restart at least one
          restart command has arrived.

        -rewind  msec
          When input is a live microphone device, and there has been some continuing input at the
          moment adintool resumes, it start recording backtracking by the specified milliseconds.

   Concerning Julius 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.

        -chunk_size  samples
          Audio fragment size in number of samples. (default: 1000)

        -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
          (using mic input with alsa device) specify a capture device name. If not specified,
          "default" will be used.

        AUDIODEV
          (using mic input with oss device) specify a capture device path. If not specified,
          "/dev/dsp" will be used.

        LATENCY_MSEC
          Try to set 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.

EXAMPLES

       Record microphone input to files: "data.0000.wav", "data.0001.wav" and so on:
       Split a long speech file "foobar.raw" into "foobar.1500.wav", "foobar.1501.wav" ...:
       Copy an entire audio file via network socket.
       Detect speech segment, send to Julius via network and recognize it:
