Goal

  • Understand and use common audio recording techniques with an audio deck

Standards, Terms, and Concepts

  • Interface
    • Stereo Microphones
    • Mode Indicator LED
    • Shortcut Buttons
    • Input Select
    • Transport Control
    • Record
    • SD Card
    • Microphone Inputs
    • Headphone Port
    • Output Port
  • Settings
    • Phantom Power
      • Power for condenser microphones at 48v (dynamic microphones like the Shure SM58 do not need phantom power)
    • Mono Mix
      • Only one audio channel mixed to two channels, the same sound is on each channel
    • Record Format
      • WAV96kHz/24bit – highest quality
      • WAV44.1/16bit – CD quality, good for longer recording sessions
    • File Name Format
      • Use DATE option (example: 170131-001.wav)
      • Helps keep files organized
    • Battery Options
    • Recording Modes
    • Record Levels
      • Adjust loudest level to -6dB (DO NOT PEAK IN THE RED)
      • -6 gives headroom for the recording
    • Headroom
      • Safety zone allowing transient audio peaks, loud parts, to exceed the nominal level without damaging the system or the audio signal, e.g., via clipping
    • Nominal Level
      • Operating level at which an electronic signal processing device is designed to operate
    • Clipping
      • Waveform distortion that occurs when an amplifier is overdriven and attempts to deliver an output voltage or current beyond its maximum capability

      2. Hold the mic above the talent, if possible
  • 22:33 Set your recording levels by having the talent practice the loudest lines
      • 22:47 REMEMBER TO SET PEAK LEVELS TO -6 dB
    • 23:00 Role audio
      • Audio recorder states: “Scene 1, Take 1” (as an example)
      • The slate is clicked, or hand clap, to create a nice sharp audio wave to aid in post-production audio syncing
      • Director says action
