QIM508 Digital Audio and Video Production Capture Capture2 (Tool and Task…

- - - - Frequency/wavelength/amplitude - carried by vibration over matter. There is no noise without matter to convey sound as energy.
    - - Binary 0's and 1's. Lossless. Compressed
    - - Simple formula. Sound small compared to video
    - - Clean sound and easy to transport. Range of supported formats
    - - 3rd party propriety and international standards
        
        AIFF - Apple; WAV,MP3 international agreed format
    - - Common supported formats include wav and mp3
      - Mono 22Mhz or 44Mhz optimal for size
      - For WCAG compliance audio to be supported by subtitles
      - Sound to be balanced for mid level volume
    - - simple or complex software to clip/ramp/filter/mix down as req
      - Time code editing to post sync to video
- - - - Nagra/ Zoom common field recording devices. Can be recorded direct to camera. Studio typically higher quality mike with desippulant (spelling?) and sound insulation,
- - - - Once recorded to tape, audio is stored/archived
      - Analogue track tape is (was) a world wide standard
      - Analogue tape has a theoretically better audio bandwidth (this is arguable)
      - There are many classic well loved analogue hardware processors available (EQ, compression etc)
      - Although technically a poor format, folks like the sound of vinyl (not entirely an ergonomic factor!)
    - - Good analogue is expensive
      - Cheap analogue recording equipment cannot match cheap digital for audio quality
      - Tape is becoming increasingly hard to source
      - Advanced editing of audio, including individual tracks, is difficult if not impossible with tape
      - Harder to synchronise
  - - - Better sound for cheaper equipment
      - Highly portable
      - Data can be cloned
      - Data can be transmitted over networks
      - Easy to edit
    - - Computers crash
      - Data can become corrupted
      - Confusing array of formats and systems
      - Digital audio GUI's tend to encourage visual, rather than auditory, scrutiny
      - Editing paramaters (such as when programming a synth or EQ plug-in) are tedious with a mouse
