Re: [Sursound] AmbiExplorer for Andriod version 2.1 out
Hello Brian, Thank you for suggesting using SOFA and sorry for the very delayed reply. It makes sense and I will look into it. I'm using Csound as the audio engine and the convolution opcode expects wav or aiff files (it uses libsndfile) so it won't work out of the box. I think it would be great to have a SOFAlizer opcode in Csound, I'll probably look into programming one.

Re: [Sursound] AmbiExplorer for Andriod version 2.1 out
Hi Umashankar, Sorry for the delayed reply. Any tablet or phone with Android 4.1 and up and with a CPU of at least 1GHz should work. I recommend that if you are going for a tablet to get something like the Nexus 7 (2013 model) or Nexus 9. If you are aiming at a phone, a Nexus 5 or 6 should work fine or any Galaxy S4 and up. In the future I might integrate alternative decoding techniques that might require a much powerful device so I would recommend to get something newer.

[Sursound] AmbiExplorer example file...
hi *! here's a little recording to enjoy via head-tracked binaural, for example with hector's AmbiExplorer: http://stackingdwarves.net/download/Pool-WXYZ.flac (300mb) http://stackingdwarves.net/download/Pool-WXYZ.wav (770mb) choose the wav if you download it directly to your android phone, AmbiExplorer won't play the flac. or download the flac to your computer, decode it to a wav and push it to your phone via USB. improvised chamber music, 5 musicians and a dancer (whose footsteps you may hear, very faintly, from time to time). approximate sound stage: far left, slightly in the back: recorders left: classical guitar a bit right of center: bass clarinet right: double bass far right, slightly in the back: percussions and vibraphone tetramic for ambience, individual spots per instrument. some artificial reverb to blend the spots. lots of fun with the phone tucked under the headband of your headphones. i was able to learn the generic HRTFs after a few minutes. externalisation is not perfect for me (it never is), but exploring the sound by moving around with eyes closed is a definite win compared to listening to a static rendering. you might want to reduce the default hardware and software buffers in AmbiExplorer for quicker tracking. avoid jerky movements in any case, or the illusion will break down. i have the same file in third order, write to me off-list if you're interested. have fun, jörn -- Jörn Nettingsmeier Lortzingstr. 11, 45128 Essen, Tel. +49 177 7937487 Meister für Veranstaltungstechnik (Bühne/Studio) Tonmeister VDT http://stackingdwarves.net ___ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound

Re: [Sursound] AmbiExplorer
The source for the TetraFile Android app is now available here: http://www.hcenteno.net/software/TetraFile_Android_SRC.zip It contains 3 Eclipse projects: the TetraFile executable, the Java Android frontend and the fft library used by the executable. Not included is the source for libsndfile (required by the executable), which can be found at: https://bitbucket.org/kunstmusik/libsndfile-android. I don't think that the changes I made to Tetrafile are worth for Fons to include in his main code since they are just simple log messages that are used by the frontend to display the processing progress.

I am/was aware that Tetrafile is published under GPL license. But it depends maybe also how Tetrafile is included into the program? (Cos Dalvik-VM/Java and Android development tools are Apache license.) Not really. They declare themselves that the Apache license is compatible with the GPL. Not all licences are. Cynics call the GPL a polluting licence as it requires all the code, including that from elsewhere, to be under either the GPL or a compatible one - at least, one that is not more restrictive than the GPL itself. So, for example, as I understand it, GPL code can be freely combined with code that is fully public domain (free and without any restrictions at all, including closed commercial use etc; one example is the Synthesis Toolkit - STK, and any amount of code under the BSD licence, which is essentially a standard disclaimer of responsibility). So one thing you cannot do is mix GPL and closed source and publish only the GPL parts. The point of the GPL is not simply to licence individual source files, it is more to ensure any user can build their own modified version of the application (which must then also be published under the same terms). .. See above. If you argument above is correct, things get quite difficult, because typical Linux toolkit licenses are GPL. (So and according to the argument above, you can't separate your code into GPLed and other license/closed sections. Even if you try hard to do so.) Nope, indeed you can't. There is some flexibility regarding libraries (which could be under the LGPL; but under the strict proviso that the user can relink with a different version of the LGPL library. Some of that depends in the LGPL library being dynamically linked, so the user can simply relink the binary with it. On the iPhone no dynamic libraries are allowed, so everything has to be statically linked, which means in turn that even if it is an LGPL library, everything must be made available. If Tetrafile is GPL, it cannot be treated as LGPL, and all the sources of any application using it needs to be available under that licence. Copyright holders of GPLed software can of course offer alternative non-free licences if they choosee to. The classic example is FFTW, which is free under the GPL, but is also licensed commercially (e.g. for Matlab). I don't think that licence is particularly cheap though!

Re: [Sursound] AmbiExplorer
Hi Michael, I'm sorry that AmbiExplorer didn't work on your daughter's device. If anyone experiences problems with the app please feel free to email me directly. I'm more than happy to try to figure out what's going wrong. A downside of Android development is the overwhelming variety of devices and making apps work on all of them. On a recent update I added the option of sending bug reports via email for non-crashing issues like no sound being heard. The best way of doing it is to close the app by pressing the back button or closing it in the app switcher. Reopen the app, load a sound file and hit play. If the time counter doesn't move, press the settings button on the top-right corner and select bug report at the bottom; follow the instructions for sending a log report via email. If after hitting play the app becomes unresponsive then wait for the system warning and send a report.
