Hello,

After a long while, I've decided it is finally time to update my Android
app AmbiExplorer [
https://play.google.com/store/apps/details?id=net.hcenteno.ambiexplorer ].
I'm developing it on my spare time but I'm hoping to include at least these
new features:

- Add HOA playback, up to 3rd order using Google's Resonance decoder (for
now, later will try to add a variety of HRTF selections)
- Include Google's Resonance decoder as an option for FOA playback in
addition to the current HRTF sets
- Support both FuMa and AmbiX formats
- Possibly support TBA (Facebook 360 Audio)
- Support loading custom HRTFs (I also want to look into possibly adding
SOFA support)
- I've also considered adding a VR mode where the user would be placed in a
visually neutral space (dimly lit) as an alternative to head-tracked
headphones (this might also elicit a more focused listening attitude), and
possibly add the option of assigning 360 panoramas to audio files to be
displayed during playback.

These updates will be released in stages during this year but the first 3
are already on their way and hopefully will be released soon.

If anyone has any feedback about these updates or would like to suggest any
other features or changes please let me know!

Best regards,

Hector Centeno

It's good to see the continut'growth in Ambisonics, but looking at your play store page for this app the general public needs to be made more aware of what Ambisonics is and its benefits fot the future of 'surround sound'
And on that point, sort of, i do have a question for Hector. You state on the Play Store that the app "decodes to UHJ". Now that sounds confusing, is it worded wrongly or is there something i'm missing here?

Hi Richard,

Thank you for your comments. I agree that it's needed to create awareness
of what Ambisonics is, which is why I included a short explanation and
links to resources in the app's description (I can't add more due to word
count limitations).

Regarding your UHJ question, I'm guessing it's a wording issue. Would
"transcodes to stereo UHJ" or "encodes B-Format to stereo UHJ" make more
sense?

Thanks again!

Hector

Hey Hector, thank you for your great work with Ambisonics for Android.

Are you planning to support the octomic with TetraFile?

Hi Bearcat,

Thank you for your kind words. I would like to add OctoMic support to the
TetraFile Android app, and I already had thought about it. It all depends
on the source code of the OctoMic version (octofile and octoproc) not
having any licensing restrictions. Fons mentioned that the software's
source will be available only to OctoMic buyers so I'm not sure if that
implies it won't be open source.

Cheers,

Hector

Clarification about the license of octofile and octoproc would be
appreciated; I already asked on the list but got no answer. It could be
that the license will be free/libre, so one owner could be able to
re-distribute the source code, unless a clause is specifically
forbidding re-distribution. Those who will buy and octomic will get this
info, but knowing it in advance (publicly) would help the community (as
buyers an users).

The precise license terms for Octomic/Octofile have not yet been decided.

Regarding porting to Android, at least the following conditions will
have to be satisfied:

* The complete and up-to-date source code of the Android version must
be available to all.

* It must be possible to do a binary install the Android app without
involving a Google account, Google Services, or any form of user
registration.


ATM it's not even clear if these conditions are satisfied for the
Android version of Tetrafile. The only source code I found dates
from 2014.

Ciao,

Hello Fons,

Thank you for your reply. Those conditions are easy to fulfill and I have
no problem sticking to them or any other that facilitate access to the
software.

The source code you found is the latest. There hasn't been any updates
since then (I'm planning to work on it soon). As for hosting the APK
outside of Google Play, I can definitely do that. I'll put it on my
website, unless someone has a suggestion for a centralized repository that
doesn't require an account. I'll also look into it. I will also upload the
source to GitHub so it's easier to track.

Cheers and thanks again.

Hector

Hector,

The F-Droid repo would be ideal:

https://f-droid.org/

I can help you if you are interested.

Hi Hector,

Perhaps you've updated it, but it seems fine to me.

It can have B-Format or stereo UHJ input and recodes to binaural or virtual microphones. Clear and concise.

If I had more time (there's never enough and so many things to do) and the right gadgets I'd love to hear it. I have my own way of doing this, but it's always great to compare results on different implementations in the endless search for perfection (or a decent compromise).

You seem to have got over the problem of extracting useable data from trackers, an area where I can't work out where to start. I'm working in Max, and the only option seems to get an Arduino and find suitable software that does the disentangling and present what you're looking for (mostly rotation about the three axes, possibly dominance to allow some effect from head position).

It would be a lot of learning and experimentation, with the chance that it may just end up in the cupboard of unfinished projects.

Ciao,

Dave Hunt

Hi Richard,

Regarding your UHJ question, I'm guessing it's a wording issue. Would
"transcodes to stereo UHJ" or "encodes B-Format to stereo UHJ" make more
sense?

Thanks again!

Hi Hector

This would be killer.
Right now to play 3rd order audio
remotely to clients one has to mux to blank video, and use jump inspector.
Its just as much of a pain for 2nd order facebook, and youtube first order.
There is no mobile audio only alternative, and lets face it, everybody has
a smart phone, but no speaker array.
Audio only solutions need to be created as this will be the way to get the
music biz, and consumers alike on board.
When this happens we really will have traction, as who listens to audio
always with video?

I have your app, and would gladly pay even more for this.

Would be great if your player did playlists too or maybe just shuffle.
At the moment it is quite clunky having to load files first.

Another killer feature would be stereo (or more) encoding/upmixing. Then
everyone and their dogs playlists could be used...


Best

Steve

I guess if I'm uploading the code to GitHub I could just put the APK there
too.
