Binaural DSP Spatial Audio Demo

[andrew0v]

Would anyone like to hear a demo of Binaural DSP, a custom spatial audio program I made with MATLAB? I'm happy to take song requests and receive feedback.

I've checked your CCR track on insta if it is you. For me the sound is still just between my ears. I've found I need much more ambience if I want to reliably externalize, especially pop music where every track has a different audio perspective. If you are interested I can give you a full stereo impulse response to see what I mean.

I would love to. Maybe it would be easier for you if you uploaded some sample tracks into Youtube? You'll have to find some non-copyrighted ones of course, or post very short clips comparing the binaural vs. non-binaural tracks.

I would also like to know more. If it's binaural, does this mean it must be listened to on headphones? And what processing did you do to take a stereo track and make it binaural? Did you split the tracks and apply a HRTF to it, or is it more than that?

Did you use headphones or speakers? The CCR track was pretty far back did you listen to any others? I haven't added convolution reverb yet it's tough to get it working in real-time thanks for the response.

Headphones of course. The CCR was the only clickable link on the website. Shoot me more tracks if you don't mind.
When you add convolution reverb, consider adding an ambisonic derived multichannel reverb. It is very important to have correct reverb in directionally, timing and tonality, not just an echo "soup" poured over the sound.

Preferably listen on headphones. I didn't manipulate any of the frequency curves, only crossover cutoffs. I added subtle volume automated sidechaining of low-passed channels bilateral to their original high-frequency counterparts (opposite sided to mimic being shadowed by the head). That's some of the basics. This was inspired by listening to mastering engineers talk about how they would add slight automations to their plugins, such as Noah Dalsass.

Here are the most recent songs I found with the effect being turned on and off. I'll add some more dynamic, quieter songs soon.

I don't want to hijack the thread, but every binaural solution I've met so far wants to recreate some kind of speaker in your room sound. Here is my "take" on binauralization. It is EQd for AirPods Pro2 and my personal HRTF, but should be reasonable on a Harman like headphones. Switching back and forth between original and processed a couple times with dropouts, because latency issues. Also head tracking if available adds a very strong extra layer of realism.
Turn off the lights - visual clues are still overwhelming auditory clues - and let me know.
