Evidence of Performance
Evidence of the ability to:
construct, edit and incorporate audio elements into at least TWO different multimedia sequences including:
finding and using information relevant to the task from a variety of sources
interpreting requirements from job specifications
selecting and using suitable software and hardware.
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:
identify the distinguishing features of analogue and digital audio
explain the terms: amplitude, sound waves, frequency, mono and stereo
identify the main contemporary digital audio formats
describe data rates that apply to selected digital sources
identify sampling, sampling techniques and sources for sampling digital audio
explain the different uses of Musical Instrument Digital Interface (MIDI) technology
identify the distinguishing features of selected digital audio software
explain the purpose of an audio frame when saving and producing digital audio outputs
explain the process to join multiple tracks of digital audio
identify the types of digital effects that are used to modify and integrate digital audio tracks
explain the purpose of time encoding
clarify how sequencers are used to create digital audio tracks
explain the purposes of sound cards.
Assessment Conditions
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the digital media technologies field of work and include access to software, hardware and equipment and materials required for construction and editing of sound files.
Assessors must satisfy NVR/AQTF assessor requirements.
