Hi. I want to make an owl robot that has outstanding hearing...
Meaning it could hear a mouse at maybe 30 yrds or more.
The interaction device would have visual like the phone controlled drones do and also very high quality headphones so that the client can experience the hearing of an owl in the woods at night.
Any ideas on what sort of hardware to use?
Thanks.
Hi
What about this . That way you wouldn’t need fancy processing to filter a specific noise but you can listen to noises far away.
Broadcast solution
In broadcast work, it is often necessary to get clean audio on live shoots in noisy locations. This has been easily acomplished for years using 2 identical microphones and a stereo recorder. One microphone is aimed at the noise source and the output from that mic is inverted 180 degrees, (easily done with a switchable transformer), before being recorded on channel 2. The other mic, (talent mic), is used in the traditional manner to record the desired sound and is applied to channel 1. Back in the studio, channel 2 audio is mixed with channel 1 audio thereby cancelling out the noise, (since it was recorded 180 degrees out of phase with the source audio). This method can be used live with no computer or software and works quite well and has for many years.
I played a trick on our producer one time and made him a test tape with color bars and a 1kc test tone. I recorded one channel 180 degrees out of phase with the other channel. When he listened to the left or right channel, it was perfectly normal, but when he mixed them, dead silence. Really messed up his mind for awhile
