Tech Specs

CloudSynth is a native iOS App with an Open Source heart.

The browser for sounds has been developed using the SoundCloud API.

The Audio Engine has been developed as a PD (Pure Data) patch, while libPD is taking care of the rest.

The communication between the parts and the interface has been developed in Objective-C.


CloudSynth was developed during a 24 hours hackathon, Audio Hack Day, at Campus Party Europe in Berlin, August 2012.

The team developed the main functionalities and interface in one day.
CloudSynth won first prize against 10 other hacks!

To optimize user experience, more features have now been added.
