Tutorial 4: Stereophonic Techniques

Ron Streicher

Op zaterdag 28 april 2007 organiseert de Nederlandse sectie van de AES een tutorial bijeenkomst met als onderwerp "Stereophonic Techniques".

Dit tutorial wordt gegeven door Ron Streicher en is bedoeld om onze leden in de gelegenheid te stellen om basiskennis over dit onderwerp op te doen. Het tutorial zal in de Engelse taal gegeven worden.

Stereophonic Techniques
- the what, how, and why of stereophonic techniques: spatial perception and the ear-brain hearing system; coincident, near-coincident, and spaced microphone techniques; surround sound techniques; several comparison demonstrations of stereophonic perspectives also are presented and analyzed
- approximately 3 to 3.5 hours, depending on the number of examples played.
- What is stereo? Why and how do we hear with spatial acuity? How do we realistically capture and reproduce the stereo soundfield with just two microphones and two loudspeakers? These are but a few of the questions discussed in this in-depth seminar.

The session begins with a discussion and demonstration of how the human ear-brain hearing system works. This is followed by a historical overview of the development stereophonic recording.
The main body of the session presents a comprehensive analysis of the various common stereophonic microphone configurations, and concludes with numerous recorded examples for evaluation and comparison of the techniques discussed.
