control games or applications by making real-world sounds
SampleSumo's Percussive Sound Recognition (PSR) engine is a middleware package that analyzes incoming audio (for example from a microphone input) and listens for occurrences of pre-defined percussive sounds.
These trigger events can be used to control various gameplay elements: the sound of tapping on the table could trigger a jump action, the sound of hitting a glass could cause a protection shield to pop up, the sound of hitting a box could cause a canon to fire, etc...
The PSR engine is available as a C/C++ library with documentation, development guide and example code. We currently support Windows, MacOSX and iOS (let us know if you would like to use it on other platforms).
Contact us for more details, pricing info or an evaluation license to get you started.
If you would like to evaluate the technology yourself, we offer the following options:
Windows and MacOSX
simply download our technical demo application
contact us with your iPad's Unique Device ID and we will give you access to the technical demo application via TestFlight
Brian Crecente from The Verge interviewed us at GDC 2012 in San Francisco about our middleware and the demo game we demonstrated there. This gives a nice introduction to the technology and what it can do:
Domotics and security
One of the first games using this technology, was a tech demo game called "Cows'n'order" developed by a team of game developement students from mADE/NTHV in Breda (NL). It's a fun and collaborative game, in which 4 cowboys need to guide their cows over a track filled with obstacles. Each time an obstacle can not be avoided, a cow dies... Each cowboy can remove certain obstacles, but only if he is at the front of the group at the right moment. The fun thing is that you can make your cowboy move to the front by hitting the right real-world object: a glass, a box, a table, two spoons, etc... This is the trailer they made for the game:
