Binaural Microphone Project - Part 1
Building a binaural stereo microphone with two old converted earbuds to use the human head and designing a preamplifier module for them with line level outputs so that ordinary recording devices can receive its audio for three dimensional sound playback. In this video I discuss the process of converting ordinary cheap earbuds by removing the internal speaker driver and drilling holes in them to fit in place an electret microphone element facing the opposite way using the original 3.5mm jack and cord so that the user can wear them and record the sounds exactly as they hear it around them. Later in the video I talk about the design and implementation of a simple OPAMP based low noise preamplifier circuit with soft peak limiting to drive line level audio recording equipment with attenuation control from the softest sounds to loud environmental recordings. Part 2 (will upload in a week or two) I will show the built circuit and give some audio samples of it in working operation and eventually record some video/audio in live environments as extra content for future youtube uploads.
