Overview 

This standard is about handling audio material efficiently when recording digital audio files and formats using different computer applications, platforms and media. It is about understanding which file formats to use in specific situations, and being capable of making intelligent choices regarding transfer methods, compression, file naming and storage.

This standard applies to all those who manage audio material using different applications, platforms and media.

 

Performance Criteria 

You must be able to: 

  1. follow organisational procedures and processes to manage audio material
  2. import audio material using the specified method
  3. transfer audio material between audio workstations, platforms and different applications 
  4. match interfaces between source and destination in level, impedance, polarity and format, and confirm that they have met any required synchronism
  5. confirm that sound material is in the desired format, at the required level, and has the dynamic range appropriate for the recording medium or technology
  6. export audio files to appropriate media using the most appropriate method
  7. find alternative solutions for importing and exporting digital audio, where necessary
  8. save digital audio files in specified formats in a secure location, in line with organisational practice
  9. ensure that the integrity of digital audio material is maintained throughout its use 
  10. complete recording within specified timescales
  11. remedy defects in sound, failures in systems, and mechanical breakdowns that are within your responsibility and area of expertise
  12. seek assistance when defects and breakdowns are beyond your own expertise

 

Knowledge and understanding 

You need to know and understand: 

  1. the basic principles of sound and acoustics
  2. the key differences between analogue and digital audio material
  3. how to manage digital audio material correctly
  4. the various protocols and methods used to transfer digital audio material
  5. the various protocols and methods used for storing digital audio material on workstations
  6. the main characteristics of microphones, accessories and applications
  7. the difference between mono and stereo audio and its implications
  8. the operating characteristics of portable digital recorders
  9. which file formats are uncompressed or compressed, the different forms of compression, and the implications of this in terms of copying and broadcast or delivery use
  10. the meaning of an audio file’s bit depth, sampling rate and bit rate, how they are connected and the implications for the file’s use
  11. how a file’s audio characteristics will affect its size when stored on a digital audio workstation
  12. which file formats are used for specific platforms and applications
