Soundlocale is a web application for playing a mix of geotagged sounds based on the listener's present coordinates. As the listener travels through a space, the sounds adjust in volume based on their proximity.

This project was proposed at the September, 2013 Hacking Arts conference in Cambridge, MA by Qingyang Xi, and has been developed thus far by Mark Breedlove.

Install the dependencies in requirements.txt:

$ pip install -r requirements.txt

Soundlocale relies on avconv, which is part of the Libav fork of ffmpeg. On Debian / Ubuntu, this is part of the libav-tools package. You will also need the libvo-aacenc0 package for transcoding AAC. See the provided Vagrant / VirtualBox VM, which runs Ubuntu 14.01 and resolves all of the dependencies.

See README-vagrant.txt. With the included Vagrant and Ansible files, you can easily spin up virtual machines that are configured to serve up this application.

• Transcode files: need both m4a and ogg.
• Web Audio API for mobile Safari support.
• Progress indicators
• Add Vagrant and Ansible files to ease installation, testing, development
• Support Gevent
• Fix login response for incorrect password.
• Maps! Geolocate uploaded sounds. Show positions of sounds on home page.
• Main page: list users who have sounds in the current area. Choose which user to listen to.
• User list page: Show users, click on user & see map of sounds.
• Cloud storage
• Asynchronous transcoding

• A user will create programs, which are just metadata pages that can be used to group sounds together and give synopses.
• A next iteration may incorporate compass heading, but that seems to require that the device be moving. With heading, the sounds could be panned, but that should be governed by an attribute of the sound.
