DESCRIBE ADVANCED MICROPHONE TECHNIQUES AND THEIR USE FOR MULTI-CHANNEL RECORDING AND REPRODUCTION.

11 May DESCRIBE ADVANCED MICROPHONE TECHNIQUES AND THEIR USE FOR MULTI-CHANNEL RECORDING AND REPRODUCTION.

LO1 & 2 combined written open-book assessment.
You are required to complete the following written assignment where your knowledge and understanding of stereo and multi-channel recording and reproduction techniques will be assessed.

You must answer all of the following questions correctly to pass the assessment.

• Describe advanced microphone techniques and their use for stereo recording and reproduction.
• Describe advanced microphone techniques and their use for multi-channel recording and reproduction.

Q1(a): Choose TWO of the following microphone techniques:

A/B (Spaced Pair),
Mid / Side (M/S),
ORTF (Near Coincident)
X/Y (Coincident)
Blumlein Stereo

Then:

With reference to level, time and phase differences describe how each technique captures and reproduces a stereo image.

You should also make reference to specific reproduction requirements, panning and/or summing where relevant.

Identify and explain advantages of the technique and also identify and explain compromises of the technique

Explain the suitability of the technique in terms of mono compatibility

Use Diagrams (with references) to support your evidence

Q2(a): Choose TWO from the following list of multi-microphone / surround techniques:

Hamasaki Square
Corey / Martin Tree
Decca Tree
IRT Cross
Fukada Tree
INA5

Then:

Include information about microphone placement within the array, polar responses, relative angles and placement relative to the source.

With reference to level, time and phase differences describe how each technique captures and reproduces a multi-channel image.

You should also make reference to specific reproduction requirements, panning and/or summing where relevant.

Identify and explain advantages of the technique and also identify and explain compromises of the technique
