Final Eartell production in action
I connected the eartell product and collected data from 5 different microphones, I passed sound from various angles and at various heights and collected the data, I found that the average ITD between the amplifiers in 0.12 and the ITD from end to end microphones is 0.6msec, I converted the analog signal into sound pressure level db using a standard formula now based on the sound source and the sound signal it received my custom program will automatically adjust the ITD and mix it. I still need to add the mixer circuit which will be part of the end product.

Finalizing and securing microphones
Final Product: After lot of thinking and trying I ended up using the clips tied with zip on one side inserted into a bone conduction headphones, it does capture the sound now from all directions and the data is retrieved for a mixer circuit, The data is then extracted as a file and manipulated using audacity software. After multiple iterations of the sound recording and mixing, I am able to find the perfect spot for the TDOA.
