Sound 2 Light

Is the free 'beat detector' for FreeStyler and it is included in the FreeStyler setup. It records the audio from your favorite selected soundcard, analyzes the audio and calculates where the beats are. Those beat moments are sent to FreeStyler for nice light shows. With every beat you can make FreeStyler to go to the next step in a sequence or make a light flashing. We have implemented a beat divider, so sou can send one beat signal to FreeStyler after 2 (or 3 or more) beats. There's also an opposite of that, the beat multiplier. One beat from your audio signal, results in 2 (or 3 or more) beat signals that are sent to FreeStyler.

How does it work?

SL.exe gets installed in the path where you installed FreeStyler.exe. Once you activate the sound 2 light feature in FreeStyler, this Sound 2 Light application launches and off you go! After you started the the beat detection, FreeStyler receives the beat signals from Sound 2 Light and does with it what it needs to do.

Is it free?

Yes. It is free for use with FreeStyler.
No registration required.
Just download and use it, together with FreeStyler.

I want to use Sound 2 Light for my own home-brew application

Every once in a while we receive e-mails from various people asking us they can use this Sound 2 Light app for their own home-brew products, other than FreeStyler. We even received questions from a few (some big) software and hardware fixture brands to get involved with them. While we are really happy with people and companies wanting to do that, we initially let them know we are willing to work with them, but unlike our work for FreeStyler we won't do that for free and will be asking a market-based fee depending on the situation. Just use it with FreeStyler. Then its free.
