DR1K 35: Sound Production Practice 2
LO2 Assessment – Written Report
The written report should be around 900 words, and must include the following:
♦ justification of the microphone choice in relation to the production brief and audio source to be recorded. Reference should be made to microphone frequency response, type (eg dynamic, condenser), polar response pattern and sensitivity.
♦ justification of the microphone array arrangements in relation to the production brief.
Reference should be made to the suitability of the array(s) used in relation to the brief.
♦ an explanation of phase anomalies, in relation to microphone and loudspeaker arrangements, with regard to image perspective and timing. This should contain information on the main characteristics (localisation, perspective and phase anomalies) of different array arrangements (eg coincident pairs, spaced pairs, near coincident, spot microphones and binaural arrays). For speaker arrangements, explanation should be of the number of speakers used, their frequency response and their set-up angle in relation to image perspective and timing for the listener.
♦ an explanation of the mixdown process including: channel bussing, panning, equalisation and speaker placement in relation to the surround format selected. This should include a detailed account of the mixdown process in reproducing an accurate representation of the audio source.
