✨ ADINREC(1) — the audio recorder bestie 🎀

okay so adinrec is literally the manual name you need to know, bestie 🦋 it's the tool that opens an audio stream, listens for an utterance, and saves it to a file. no cap, it's so iconic 💅

🎤 NAME

adinrec — record audio device and save one utterance to a file 🌸

💖 SYNOPSIS

adinrec [options...] {filename}

🧚 DESCRIPTION

okay so adinrec opens an audio stream and detects when you start talking (an utterance input) 🎤 then it stores that to whatever file you name ✨ the detection is done by level and zero-cross thresholds, which is giving very scientific main character energy 🔥

the default input device is the microphone 🎀 but you can switch to other audio input sources, including the Julius A/D-in plugin, by using the -input option 💜

the audio format is 16 bit, 1 channel, in Microsoft WAV format 🌈 if the filename you give already exists, it gets overridden so be careful bestie 💀

if filename is -, the captured data gets streamed into standard out with no header (raw format) 🫶

🌸 OPTIONS

adinrec uses JuliusLib and adopts Julius options 💅 here's the full list of valid ones, slay 👑

✨ adinrec specific options

  • -freq Hz, sets the sampling rate in Hz 🍓 (default: 16,000)
  • -raw, outputs in raw file format 🦋

🎀 JuliusLib options

  • -input {mic|rawfile|adinnet|stdin|netaudio|esd|alsa|oss}, picks your speech input source 🎤 specify file or rawfile for a waveform file, and on file input you'll get prompted to type the file name from stdin 🫶

mic grabs audio from a default live microphone device 🎙️ adinnet receives waveform data over tcpip from an adinnet client 🌐 netaudio is from DatLink/NetAudio input ✨ and stdin means data comes in from standard input 📥

on Linux you can choose the API at run time by specifying alsa, oss and esd 🐧

  • -chunk_size samples, the audio fragment size in number of samples 🧩 (default: 1000)
  • -lv thres, the level threshold for speech input detection 📊 values should be in the range from 0 to 32767 💫 (default: 2000)
  • -zc thres, the zero crossing threshold per second 🌊 only input that goes over the level threshold (-lv) gets counted 🔢 (default: 60)
  • -headmargin msec, the silence margin at the start of a speech segment in milliseconds 🙈 (default: 300)
  • -tailmargin msec, the silence margin at the end of a speech segment in milliseconds 🫧 (default: 400)
  • -zmean, enables DC offset removal 🧼
  • -smpFreq Hz, sets the sampling rate in Hz 🍓 (default: 16,000)
  • -48, records input with 48kHz sampling and down-samples it to 16kHz on-the-fly ⚡ this option is valid for the 16kHz model only 🎯 the down-sampling routine was ported from sptk. (Rev. 4.0) 📚
  • -NA devicename, the host name for DatLink server input (-input netaudio) 🛰️
  • -adport port_number, with -input adinnet, specifies the adinnet port number to listen on 👂 (default: 5530)
  • -nostrip, Julius removes successive zero samples in input speech data by default 🙅‍♀️ this option stops it 🛑
  • -C jconffile, loads a jconf file right here 📎 the content of the jconffile gets expanded at this point 🧠
  • -plugindir dirlist, specifies which directories to load plugins from 🧚‍♀️ if several directories exist, list them as a colon-separated list 🌈

🌍 ENVIRONMENT VARIABLES

  • ALSADEV, the device name string for ALSA 🎧 (default: "default")
  • AUDIODEV, the device name string for OSS 🔊 (default: "/dev/dsp")
  • LATENCY_MSEC, the input latency of microphone input in milliseconds ⏱️ a smaller value shortens latency but sometimes makes the process unstable 😭 the default value depends on the running OS 💻
