Application
This unit describes the skills and knowledge required to perform restoration work on recorded audio tracks.
It applies to individuals who restore fragile and archival audio tracks in film, television, radio, audio post-production and archival environments.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Clarify scope of restoration project | 1.1 Interpret documentation and confirm restoration requirements with relevant people 1.2 Locate source material for restoration and confirm that it is the most original and best quality recording with relevant people 1.3 Evaluate condition of source material and discuss its fitness for playback or restoration with relevant people |
2. Prepare source material for digital transfer | 2.1 Repair and clean source material in preparation for playback as required 2.2 Select audio playback and recording equipment to provide the most authentic audio reproduction, taking into account fragility of the source material 2.3 Set playback paths and recording settings to generate a flat, transparent and (where possible) uncompressed file 2.4 Set audio levels to achieve maximum fidelity |
3. Make digital recording of source material | 3.1 Create digital recording of source material in line with restoration requirements 3.2 Monitor recording and mark sections that contain audio artefacts or damage 3.3 Record from other sources if sections of original version are missing or heavily damaged |
4. Apply restoration techniques to audio tracks | 4.1 Select the most appropriate restoration equipment and tools 4.2 Apply manual restoration techniques to the most audible artefacts and faults 4.3 Use automated restoration processes to de-noise audio tracks as required 4.4 Seek feedback on restoration work from relevant people, and make adjustments as necessary |
5. Make a copy of restored audio tracks | 5.1 Apply post-production processes, including signal and noise processing, to restored audio track as required 5.2 Create master copy of restored audio track in the required format, taking into account its intended end use 5.3 Deliver master copy to relevant people in line with restoration requirements 5.4 Complete required documentation in line with restoration requirements and enterprise procedures |
Evidence of Performance
Evidence of the ability to:
interpret restoration documentation and requirements, in consultation with others
identify and remove unwanted audio artefacts and repair damage
create a digital recording of source material
use appropriate equipment to restore digital recording to meet restoration requirements
apply correct post-production processes to restored audio tracks.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
Evidence of Knowledge
To complete the unit requirements safely and effectively, the individual must:
describe the methods used to evaluate the condition of audio tracks
describe the different types of playback and recording equipment used in audio restoration work
explain the manual restoration techniques used to remove audio artefacts
explain the automated restoration processes used to de-noise audio tracks
describe the restoration equipment and tools used in audio restoration work
explain the issues and challenges that typically arise when restoring fragile and archival audio tracks, and how to address them.
Assessment Conditions
Assessment must be conducted in a safe environment where evidence gathered demonstrates consistent performance of typical activities experienced in creative arts industry environments. The assessment environment must include access to:
audio tracks
audio playback and recording equipment
audio restoration equipment and tools
restoration documentation.
