If you are trying for simplicity, maybe you can use autocorrelation of the ADC samples and find the timing differences. (Or is this what you are doing in frequency domains?) Of course another approach could be feeding it through a deep learning network. Instead of recurrent, you could have the input layer be insanely large to encompass a few hundred milliseconds of audio samples. (You would need an embedded TPU module for this of course)

okay first thing, wow this is amazing. second i was wondering if you had a link to the code. this is an amazing project that i think would be fun to make aswell. and also do you have a file for the stand that you made because that is amazing. again thank you and amazing job that is fantastic

Excuse me Sir, I have some questions I wan to ask, if you have the time to response. First of all thank you for preparing such videos. Here are my following questions: 1. I am curious as to how you used FFT in determining the DOA of sound source? Does the implementation of FFT matters significantly? 2. I have some hard time understandind real time implementation of using the sensor. Would you recommend me a book or project I could do to understand the real-time implementation? 3. I was wondering if you have tried using Beamforming techniques such as Delay-Sum method? There are concepts such as steering matrix, steering vector. Perhaps you can also consider it. Thank you for your time. Your feedback will be greatly appreciated.

Hi, here are my answers: 1. I used the FFT to determine the amplitudes of the different frequency bands and compared those frequencies against each other. Doing this does seem to work better than to just compare the raw signal amplitudes, so I would say it matters slightly. 2. I don't really have a resource to help you understanding the real-time implementation except the search term "discrete signal processing", but I can offer some more information: The microcontroller records raw data from all microphones for a specific time. Afterwards, this data is processed. So in this case, the whole program is semi-real-time, because it always processes data from the past. 3. I haven't tried that before but it does sound interesting, it will go onto my ToDo list. Who knows when I will actually tackle it, the list is currently very long. ^^ Thanks for the engagement and the questions!

This is impressive small projects, starting from scratch to this level including the continued development in part two! Good work! Theory and practice are nicely connected. It would have been interseting to have alittle elaboration also on calculating distance to the sound source and following sounde, but again, really nice project you present. CUDOS!

@techdudes996 8 ай бұрын

@@NachiketRakhonde The reason could be different things, it might help to know what the error message says. Try googling the error message itself, maybe you can find the reason for it. As a general guideline, you'll need a separate IO pin for each sensor and configure each as an input. To read the values, you need to call "analogRead" for each pin separately.

I dig it. 50 years ago I was into all the technology but then life happened. Usually I'll revisit all of the problems and find them all to be solved. Not here, though. I'm a turkey hunter. Working in the steel mill caused me to lose hearing and I cannot turkey hunt like I used to. The method is to stand in the dark of the morning, listen for a gobble, then go to cause of the gobble and pretend to be a hen to call in the turkey. I hoped that someone would have a device that would hear the sound and direction of a gobble for me, but not in my life time. I thought that the microphones would be farther apart and the timing of the sound would tell the direction, not the amplitude as you do. It occurred that if there were walls around the microphone (imagine a child drawing a sun) then the clearest one would determine the direction such that it would act like polarizing as in light. (If the sound came at an angle it would bounce off a wall and cause a distortion. So, to me, there seems to be 3 ways but probably much more. Oh well, not in this life times. Thanks for the video, though.

I've been watching the videos for a while and I have to say that I really hope to make one in the future since having a mini version of my favorite killer robot AI is a dream come true. But I do have a question. Are you adding AI to her like so she can just randomly talk to you or like learn from you?

If you don't include the display, all of the sets for singular components and some other stuff for future upgrades, you should get away with ~250€. If you already have stuff like perfboards and dupont connectors, its even less with ~200€. That would only include the body itself and the required electronics for the lamps and servos

@techdudes996 Жыл бұрын

Glad you like it! My sources were mainly from lectures in my Bachelor studies, that's why I skipped sources in this video. Since you probably need the theory behind Fourier transform and linear systems theory, maybe search for both of these terms on either Google or KZbin or somewhere else. I have a German source for linear systems (ISBN 978-3-446-46134-5) and a potential English book for Fourier transform (ISBN 978-0-521-80926-9). Maybe that's a first starting point for sources. Anyway, good luck with your project!

@@Naber796 You can either use the mathematical exact approach or use an iterative algorithmic approach. For example you could say that your microphones are located at Position P1, P2 and P3. Then you detect the sound with the 3 microphones. Microphone 1 detects it at time t1 and microphone 2 at t2 and microphone 3 at t3. Then you take a few guesses for position X which represents the origin of the sound. Then you check each guess with the real observed values and then add a random value to the best guess and repeat this for a few times and then you should have a rough location of the origin of the sound.
