Hello,

I just would like to share that I've been working on an app currently
available in the Google Play store named AmbiExplorer. It allows you to
listen to ambisonic B-Format recordings decoded as binaural stereo and
stereo virtual microphones. It can do head-tracking using the internal
sensors of the device or an external bluetooth tracker (BT connectivity
available in the upcoming version 2). It uses Csound as the audio engine. 

I didn't share the news here before because I was considering using Csound
only for prototyping and later building my own sound DSP engine but for now
I've decided to stick with Csound, mainly for practical reasons and because
I'm interested in contributing to the development of Android Csound.

Links to two demo videos:

Version 1 demo: https://www.youtube.com/watch?v=EJc85yACwjk
New features in the upcoming version 2:

Version 2 will include library handling (with option to import files from
online libraries), geotagging, map view, location based playback and
selection of HRTF from the LISTEN library.

The app listing in Google Play:

Any suggestions or comments are welcome! The only occasional issue I'm
facing with Csound (as described in this  thread
http://csound.1045644.n5.nabble.com/Android-channel-reversal-td5736512.html 
in the Csound-dev list) is that the channels would reverse due to buffers
being dropped (even when using larger -b and -B values).


Thank you! 

Hector Centeno

Hi Hector,

A huge +1!  What a fantastic idea and the app looks great.  Hopefully
the channel reversal issue can be sorted out soon.

I've added a news post for this on the csound.github.io site:

Thanks for sharing!

Thank you Steven and Tarmo for your kind words. Also thank you Steven for
including my post in the csound.github.io site. If there's anything I can do
to help fix the channel reversal problem, please let me know.

I hope to have version 2 out soon. I'm still fine tuning some details and,
unless something major arrises, I'm expecting to publish it this or next
week.

Best,

Hector

regarding the channel reversal problem, if you could do a minimal CSD code 
wrapped in an app, with an eclipse project, it would help us test it here.
This is because we’ve never seen it happen, and it is hard for us to diagnose it.

Having said that, have you tried a power-of-two combination of ksmps, b and B,
as I suggested, like 64:256:2048 ?
