Elements and Performance Criteria

1. Identify and describe formats of digital audio
   • The distinguishing features and uses of analogue and digital audio are determined
   • Terms describing audio characteristics (amplitude, sound waves, frequency, mono and stereo) are used correctly
   • Contemporary digital audio formats and their application in achieving defined outcomes are identified
   • Data rates for major digital sources and their relevance to defined outcomes are determined
   • Appropriate methods for saving and producing digital audio outputs are determined for a range of sources and destinations
   • Sampling techniques and sources for digital audio appropriate to defined outcomes are determined
   • Uses of MIDI technology are determined
2. Use digital audio software
   • Appropriate digital audio software is assessed and selected for the job
   • Programs are used to edit and manipulate audio according to the job brief
3. Edit digital audio
   • Single and multiple audio tracks are edited to achieve a defined outcome
   • Multiple tracks of digital audio are joined according to job specifications
   • Digital effects are employed to modify and integrate digital audio tracks according to job specifications
   • Time encoding is applied to single and multiple edited digital audio tracks according to job specifications
   • An audio track is inserted into a multimedia production sequence according to job specifications
4. Construct a digital audio track
   • Techniques for hooking sounds are identified
   • Defects on sound recordings are eliminated and/or treated
   • Special effects and mixing techniques are used on an audio track according to job specifications
   • Sequencers are used to create digital audio tracks according to job specifications
   • MIDI and sound cards are used to create digital audio according to job specifications
   • An audio track is produced using appropriate track construction software and hardware
   • Audio tracks are saved in the appropriate file formats

Required Skills

The following skills must be assessed as part of this unit OHS in relation to operating machinery such as safely switching off machinery before cleaning is started Collecting analysing and organising information by identifying digital audio formats Mathematical ideas and techniques by identifying digital audio formats Problemsolving skills by employing digital effects and modifying and integrating audio tracks Use of technology by incorporating audio into multimedia presentations

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria Required Knowledge and Skills the Range Statement and the Assessment Guidelines for this Training Package
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Evidence of the following is essential Incorporate audio elements into different multimedia sequences according to job specifications and the Performance Criteria Incorporate audio elements into at least TWO different multimedia sequences according to job specifications and the Performance Criteria There should also be evidence of Ability to find and use information relevant to the task from a variety of information sources Ability to use a range of software suitable for incorporating and manipulating sound Evidence for assessment may be gathered from assessment of the unit of competency alone or through an integrated assessment activity
Context of and specific resources for assessment	Assessment must ensure assessment may take place on the job off the job or a combination of these Off the job assessment must be undertaken in a closely simulated workplace environment
Method of assessment	A range of assessment methods should be used to assess practical skills and knowledge The following examples are appropriate for this unit direct questioning combined with review of portfolios of evidence and third party workplace reports of onthejob performance by the candidate
	Holistic assessment with other units relevant to the industry sector workplace and job role is recommended for example CUFMEMA Update web pages CUFMEM12A Update web pages
