WARNING: This is a specialized app and not a generic audio player. It wont play regular stereo audio files nor MP3s. If you are not sure what ambisonic audio is, very likely this is not the right app to get (read below to learn more). The Manual is also available here: http://www.hcenteno.net/ambiexplorer-manual/Version 2.0: http://youtu.be/gOsfo8or_0EUser Manual available in the Settings/About section in the app (located at the bottom of the Settings menu, which is accesible through the three-dot icon on the top right).AmbiExplorer allows you to listen and explore ambisonic B-Format and UHJ audio files. It does it by decoding to stereo binaural or virtual microphones. You can decide were you want to be facing in the soundfield by moving a virtual 3D panner that lets you rotate and set the angles for either the virtual human head or the virtual microphones. The polar patterns for the microphones can be set ranging from omni-directional to bi-directional.The positioning sensors in a phone or a Bluetooth tracking device can also be used for head-tracking. This can give you the option of attaching the sensing device to the top of your head or headphones and get a more realistic immersive 3D sound experience.Support:For any questions, suggestions or issues please email me (use the Developers Send Email link below)Important Compatibility Notes: * This app currently requires Android version 4..0 or above and works better on recent devices with a powerful CPU.* For the positioning feature using sensors, a device with accelerometer, gyroscope and magnetometer (compass) is required. If your device doesnt have these sensors this feature will be disabled.* This app has been tested on recent high-end devices. It will very likely work on many more devices but please try to check as soon as you install so you can request a refund if necessary (Google gives a 15 minute time window only). Before requesting a refund try contacting the developer.Features:- First and second order B-Format and UHJ playback- AmbiX and FuMa support.- Optimized 1st order CIPIC HRTFs from the Ambisonic Toolkit www.ambisonictoolkit.net and LISTEN.- Library management with export and import locally and online via .ambxp files (csv format)- Geotagging, map and location aware playback- Handles one 4 channel or split two stereo B-Format files and UHJ stereo files (wav, aiff, amb or ogg)- Outputs to binaural, stereo virtual microphones or stereo UHJ- Soundfield rotation and virtual mic positioning using a multitouch interface- Use the devices orientation sensors or external Bluetooth devices for head-tracking Razor [ https://github.com/ptrbrtz/razor-9dof-ahrs/wiki/Tutorial ] and WitMotion JY901 attitude sensor [ http://www.wit-motion.com/english.php?m=goods&a=details&content_id=92 ]- Offline export to wav or ogg files- Audio file sharing (DropBox, SoundCloud, Google Drive, etc.)- 5 band equalizerIf you are new to ambisonics.Some external web resources:What is ambisonics?http://cec.sonus.ca/econtact/Diffusion/Ambisonics.htmhttps://en.wikipedia.org/wiki/Ambisonicshttps://www.waves.com/ambisonics-explained-guide-for-sound-engineersWhat is UHJ?http://en.wikipedia.org/wiki/Ambisonic_UHJ_formatDownload and share B-Format recordings:http://ambisonia.com/Ambisonic recording used in the promo video by John Leonard and the Orfeo Triohttp://www.ambisonia.com/Members/soundmanjohn/ambisonicfile.2008-04-14.90346586652019.1b- Replaced old 3D rendering engine to fix compatibility issues with S72019.1a- Bug fix2019.1- Added support for WitMotion Bluetooth headtracker- Added 2nd order decoding (using Google Resonance for decoding)- Added support for AmbiX and FuMa formats- Improved soundfield rotation algorithms- Fixed multiple outdated API breakages to the mapping systemKnown Issue- In some devices it is not possible to output files to an SD card

Great for ambisonic file playback. Would be nice to have opus format supported for 4 channel file to have smaller file size

Amazing app, and the only one of it's kind as i can see for years now. Hector Centeno amazing work you have done to make this such a success. I have been able to now hear and preview my recordings directly on the field right on my Android device. Will there be any future updates planned to this App? I have already purchased and very happy so far although the interface UI does seem to be slightly aged. As another reviewer suggested, teaming up with Audio Evolution Mobile which own as well, as they have the best Multi-Channel USB audio interface connectivity for Android Mobile. It will be amazing to connect my multi-channel usb interface with Ambisonic format output and have an all-in-one on the field Recording and Live Monitoring. I see that they have teamed up with a plugins development company recently so now might be your chance. If they cant comply i suggest you can create your own app for multi-channel Live Input Monitoring with Binaural decoding. This will be a Seller and allow all-in-one solution no one else has or can provide for Android system yet. Thanks again and wish to see some future updates and add-ons in features in the future.

fantastic app, a few bits still to add, but a nice feel. I'd REALLY like to see you should team up with the Audio Evolution team. this way you'd have a great recorder to team up with, say, a Zoom F4 or F8n to do ambisonics recording, and encoding to binaural output, the perfect VR location recording setup.

This little app makes it possible to try head-tracked binaural rendering at no extra cost, if your phone has a compass and gyroscopes. Before, only a few researchers and even fewer professional audio engineers had access to such systems, now everyone can try. I was surprised how, after a short period of getting accustomed to the generic HRTFs, the sounds I hear were leaving my head and taking their proper place around me. If you aren't afraid of looking very geeky indeed, put the phone on the table in front of you, select a file, enable the sensors, reset, press play, and carefully tuck the phone under the headband of your phones, maintaining its orientation. Now the sonic image will follow your head around. Clunky, but after a few seconds to minutes your brain will buy into the illusion, which is a great experience.
