Re: [Sursound] Ambisonics recording of LOUD night club or venue?

I have a few loud bands. How about this one in B-format? Small venue with rowdy people. https://www.youtube.com/watch?v=Bqxd5KnN8ns You can also find quite a few Soundfield and TetraMic sources on https://archive.org/details/etree, but they're generally only published in stereo downmix, and you'

[Sursound] 4-channel Teensy Audio

2016-01-18 Thread Hugh Pyle
The Teensy machine is a nice, very small, processor: 100MHz ARM Cortex M4, with a very nice Arduino-based toolchain. http://www.pjrc.com/store/teensy32.html Apparently the latest update to the Teensy Audio Library supports 4-channel, CD-quality, input and output. I assume this is with two stacke

Re: [Sursound] Ambisonics on the cheap?

2011-07-29 Thread Hugh Pyle
I have one of these, and it's cheap and works well. The biggest issue is the sample rate limitation; with 8 channels you can only run at 44.1 kHz. On Sat, Jul 30, 2011 at 12:07 AM, Ben Bloomberg wrote: > Has anyone tried anything from ESI audio? It looks too good to be true. > > http://www.esi

+1. If you design a BeagleBone cape with 16 channels out (balanced or not, I don't really mind), or a dedicated system that includes the CPU, I'll want several :-) On Thu, Jul 5, 2012 at 8:16 AM, GP wrote: > Put me on your pre-order list already Dave! :-). > > Cheers Garth > Sent on the Move > >

That's really nice. It would be very interesting to see the bins color-coded by frequency, too. On Thu, Nov 7, 2013 at 11:05 AM, Fons Adriaensen wrote: > On Tue, Nov 05, 2013 at 12:32:33AM +, Fons Adriaensen wrote: > > > On Mon, Nov 04, 2013 at 05:03:29PM -0700, Mark Anderson wrote: > > >

[Sursound] Ambisonics with AirPods head tracking

2022-01-04 Thread Hugh Pyle
Hi sursounders, I've been away from the Apple audio ecosystem for a long while. But now I have some Airpods, and their head-tracked / spatialization functions are interesting. Is there a simple process for listening to FOA Ambisonic recordings on AirPods, with head tracking? I have a number of

This morning, Salem MA commemorated the 374th anniversary of the first National Guard muster. Here's the thirteen-gun Howitzer salute at about 10 metres. I managed to record this without digital clipping. That's not to say that the poor microphone or input stage weren't saturated... but for thos

Hi Justin, I've found TetraMic to be really too noisy for "quiet" (rural birdsong, etc) field-recording environments. It's really good for urban noise and regular outdoors things, but the noise floor is just too high to use in quiet places. The Soundfields seem to be quieter, judging from some r
