[Sursound] AmbiExplorer
Persuaded one of my daughters to download AmbiExplorer --very impressed with what worked! (The rotatig head is great.) However it does not play. It's a few weeks ago, but IIRC we got a status bar (?) and a clock. Besides getting no sound neither of those two budges. No error messages. It was a SAMSUNG Galaxy SIII mini GT-18190 runing Android 4.1.2 Any ideas ... ? Thanks, Michael ___ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound

Re: [Sursound] Listening to FOA B-Format with head tracking
It worked BTW. If someone can come up with a suitable ascii knob or midi interface.

It was a SAMSUNG Galaxy SIII mini GT-18190 runing Android 4.1.2 --- I've tried it on a Nexus 4, Nexus 7 92012) and nexus 7(2013). All run Android 4.4 Kitkat. It ran on all three, but the audio level on the older Nexus 7 was extremely low. Sadly, while the author put some code in to try and trap the cause of that situation I had since given away that older tablet. Since then he has also added the ability to decode UHJ tracks, which is something that i had asked for given my small library of old Nimbus CDs. I've yet to try that out. Perhaps this weekend.

Re: [Sursound] Sensory evaluation of concert halls
sursound-requ...@music.vt.edumailto:sursound-requ...@music.vt.edu kirjoitti 21.1.2014 kello 19.00: thanks for elaborating! very interesting method and survey! one thing i'm asking myself: since you can only ever have one direction per time window, does that mean that each direction estimate will trigger a complete IR decay trail from the omni mic in that direction? i.e. your directional resolution is really high, at the cost of identical timbre of all reflections? are there any perceptual drawbacks? i'm sure i wouldn't notice, unless the carpet i'm standing on is knee-deep, but... :) particularly, will the seat dip effect be averaged and spread into all directions? One time window gives one direction estimate as it is an impulse response which is analyzed. In ideal impulse everything (all frequencies from one direction) are in one sample. In practise impulses are spread in time, but the idea still works well. Thus, after the directional analysis all samples of one omni IR is distributed to reproduction loudspeakers. This results that in reproduction loudspeakers the convolution reverbs are quite sparse. However, after convolution with anechoic signal the perceived spatial sound is very natural without any coloration. I hope this clarifies and answer to your question. We have not found any perceptual drawbacks. Naturally, the quality of IR is important, the used loudspeaker should reproduce short impulse, e.g., a dodec usually used in room acoustical measurements is not very good as it emits several impulses from all elements. And as far as I understand the seat-dip effect is correctly reproduced, but I do not have any data to prove it. At least it sounds the same as in-situ in real halls.
