Interesting the apple render seems wider than the dolby render....I have noticed a big difference when using the apple iplugin on my sphere 9.1.6 input which is meant let you see how it will sound coming from apple music .... Sounds way different to the dolby Binaurel setting.. Our brains are still not used to the height thing with sound where as front to back is well different... I would say that in 50 years time of spatial audio our hearing is going to change big time.
Indeed they sound different. Height is tricky still, but it is getting better. I saw in a video or in a comment on a video the other day--don't remember which one--that humans are not really good anyway at hearing sounds coming from above. Not true at all!!! Went to a taverna the other day. We sat outside. Under a canopy type thing. Under a tree. There was wind shuffling through, birds chirping, little crackling of the tree branches as the wind went through, a helicopter from a nearby helipad flying over. I tuned out and paid attention to what I was hearing. All from above! In unbelievable detail!!! Height in audio, Atmos in particular, is such a beautiful thing!!! Binaural height algos are not all that bad now but will get better for sure. Just a matter of time . . .
The in ear mics are not ideal as the mics are outside your pinna instead of at the ear canal entrance, therefore the colouration isn't quite right, still, its a nice perception though. The HRTF is confusing as it should be ERTF or PRTF, they are simply colourations of tones added to the sound that bounces and reflects of the pinna, the head is not really important, and once understood, you would be able to see how binaural works, simply by looking at an ear! Timing differences within the HRTF papers in my opinion are not required and quite confusing for those trying to comprehend binaural audio.
I wonder if iPhone devices use CPU or DSP to decode Dolby Atmos into binaural. I think it's all used by software decoders, so most likely CPU is used and not DSP to decode Atmos. I may be wrong, this is just an assumption. On Android devices with Dolby Atmos everything is simple and clear. As far as I know, they always have 4 decoders AC3, AC4, EAC3, EAC3 JOC and all are decoded in hardware using the smartphone's DSP. Do Apple devices have the same implementation? It would be very interesting to know, thanks.
Yes. EAC3 JOC (aka DD+JOC) is also used on iPhone but it gets tricky since some of the Spatial Audio processing might be happening hardware side on the A-chip. No definitive info on this (that I'm aware of, at least). Thanks for watching!
@@thelivingroomstudios Got it, thanks. And can iPhone decode AC4? Because from my personal experience it sounds much better than EAC3 JOC and as far as I know it works with binaural settings (near, mid, far and off) from DAW. As far as I know, the AC4 format is used in Tidal and Amazon Music.
If the stereorecording of the guitar is placed in the L and R channel in the Dolby Atmos bed, it shouldn’t sound like it does in your example, or should it?
I don’t have enough experience yet, but I rely on what I have read. A stereo signal panned hard front left and right in the bed, will sound almost like a pure stereo signal. - What is your experience and explanation?

I’m intrigued as to why the uploader isn’t responding to my insights for binaural audio…. I smell fear lol 😂

@@evil.baker23 AFAIK the iPhone does not decode AC4

Care to elaborate?
