![]() I rant about the Boya purely because its sensitive enough without soldering you can plug direct into a soundcard. You can pick up 9.7mm unidirectional electrets for about £0.20 each not as good as the Boya and for voice capture it has some simple advantages over a omnidirectional. The Boya seems to work well and all it is, is a 14mm high quality directional electret in a very well made metal case but just a very good one for price. I am sort of rattling on here as you mentioned ‘octaprints’ and it would be so good if someone with 3d printing skills might have a look what might be the best budget option by far. The Boya is a unidirectional mic which just means it has a cardioid pattern which helps give a small amount of echo & noise suppression which when close up it does help much with AEC. I find its rare that placement is in a centre of a room as often from walls to tables they are usually in position where much of the 360 of omnidirectional is not used. Lols the Boya is actually good but I was stressing get audio in/out on the same device as AEC/barge-in can be pretty important later on. I found those and a blind recommendation but does actually seem to be speaker/mic in one tidy puck. PS I will post again if you want the basic low down on audio engineering for arrays. Not sure the module for the ps3-eye presume its snd-usb-audio but cat /proc/asound/modules when plugged in and again when ps3-eye unplugged will tell you that one on the host. Options snd slots=snd-usb-audio,snd-bcm2835 Sudo nano /etc/modprobe.d/nf on the host options snd_usb_audio index=0 I tend to be a bit OCD so I do this just to get a better soundcard order. If you are using docker then remember to connect to the container. It should still work though and should list but now that RaspiOS defaults to pulseaudio depending on if you use the desktop or lite version and if you arecord or pyaudio it may or not work. Its just one of those PC myths that because its an array its any good, it was really good but that was the Sony software that was in the PS3 not the mic. ![]() Its debatable if the sum of the channels is an increase over the sum of the SNR which will happen and also side on it forms a high pass filter. That still doesn’t explain why its not recognised as the drivers are not great but they do work even though they are a reverse engineer hack that have had the same niggles for over a decade. I should point out that the IR filter has been removed from the camera.Its sort of pointless as the beamforming algs to make it work where in the PS3 eye. Only light seen was the 3 LEDs on the clip. The Delanclip/Opentrack/PS Eye combo does not have that issue. Too many light points detected to make it usable. TrackIR was seeing loads of light points even with the filter set to max as well as the LED brightness.Įven using the Delanclip in TrackIR with sunshine proved to be problematic. Where my computer is located, there is a window behind me, and, even with the curtains drawn, if there was any sunshine, the Vector Clip just would not work correctly at all. ![]() No difference between them at all, except for maybe a slightly smoother experience in TrackIR. ![]() When both systems were working, I could see no benefit in spending £150 on TrackIR. Opentrack has the same curve adjustments are the 6 DOF, and the PS Eye camera driver has the same - if not better - filter options for optimum conditions. ![]() to just as I like them, I can honestly say, that I see no benefit of the TrackIR system compared to Opentrack. So, after spending most of yesteday setting up curves etc. So, I bought one with the Vector Clip and decided to try it out with the Delanclp as well, as others have said it is superior to the plastic TrackIR Pro Clip. After a year of using Opentrack/Delanclip/PS Eye, I thought I would check out TrackIR out of curiosity. ![]()
