          - record audio device and save one utterance to a file


       adinrec [options...] {filename}


       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).


       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)

          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.

        -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)

          This option enables DC offset removal.

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

          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.

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

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

          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.


          Device name string for ALSA. (default: "default")

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

          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.

       The same as Julius.
