Can you hear me? : reviving binaural recording

Abstract

This dissertation is based on a method of 3D audio capture called binaural recording. Its aim is to put the recording technique to uses which are not normally associated with it. These include the multi-track recording and overdubbing of a musical piece and also the application of binaural to audio-visuals. Furthermore, a comparison with an industry standard stereo configuration, XY micing, is also explored. The methodology consists of the design, building and calibration of the three known methods of binaural audio capture. These are: the binaural dummy-head, the Jecklin Disk and the in-ear mountable system. Simultaneous audio capture will occur with two binaural methods and an XY control configuration whilst a point of view angle is shot and recorded to motion camera. A group of 12 people from different age groups and from both genders will then be tested through a questionnaire and discussion for a comparison between a binaural and an XY take. Results showed that 100% of the tested population preferred the binaural take, which had a higher percentage of accuracy for everybody throughout all criteria than its XY counterpart. The results also prove that this technology is perfectly adaptable to both a musical as well as an audio visual environment, coping well with overdubbing and other advanced audio tools. This technology only makes use of a stereo signal and hence it is applicable to many different communicative scenarios and current forms of broadcast media. Current and future uses include the application of binaural recording to sound effects, radio dramas, audio visuals and film; internet, as a learning aid and others. And we've only just scratched the surface. Further research is highly encouraged.
