Mixing Audio signals from 5 mic’s:
I am placing the mic’s in 5 different angles so that they cover the sound signals from all 5 directions, left and right ear, left and right head curvature, one in the center back of the head.
Mix Sound signals after editing to adjust ITD:
All the 5 mic’s capture the sound and the sound signal is mixed into one audio source, once it is mixed into one audio source it becomes mono and it is difficult to adjust the sound based on the ITD and direction of the sound.
Mix Sound signals before editing to adjust ITD:
All these capture the sound signal and the sound signal will be modified based on the proprietary algorithm. Once the final signal is available it will be outputted into a single audio. Processor knows the source and direction of the sound, it can calculate the time difference, sound pressure and intensity for the same frequency from each of the audio signal. Hence I decided to adjust the sound signals and then mix into one for transmission through bone conduction.
