Abstract:
Ambisonic audio is an immersive audio format that can be used to enhance the audience’s
perception of sound/user experience. In an ambisonic recording the sound sphere (or area
recorded accurately) includes the full 360 degrees around the microphone, which means that it
may provide more advanced localization than a traditional recording. A traditional recording
would typically place localization on a line where the audio would be placed anywhere from left
to right but would not include any height information. This difference in where the
height/localization information comes from is what makes an ambisonic recording different from
a traditional recording. Additionally, although ambisonic audio is an older format (started in the
1970s) it has become popular recently with the use of Virtual Reality and 360 degree videos.
This thesis focuses on the exploration of the ambisonic audio topic, the recording of ambisonic
audio using primarily the NT-SF1 microphone, and how to encode/decode/use these ambisonic
recordings in practice. It will also look at practical applications for using ambisonic audio.
