Sound to Light Interface

Sound 2 Light is the free 'beat detector' for FreeStyler - it records the audio from your favorite selected soundcard, analyses the audio and calculates where the beats are. Those beat moments are sent to FreeStyler for nice light shows. you can make the fixtures or sequences (including the DMX400) react to the music.

This S2L application replaces the old SL.exe that was delivered with FreeStyler 3.1 and older. In FreeStyler 3.2 and newer this S2L application is delivered by default. Click here for webpage and download

OBS: Be sure to use the most recent version of S2L (beta 1.0.8) since the earlier version (1.0.5, in the freestyler package) has a bug preventing it from proper function on some installations.

The FS forum user remco_k is the developer of the new Sound 2 Light program and he continually upgrades the program. This page will describe the features for the latest beta version 1.0.0.8 but it will be noted which features is in the stable version and the beta.

Sound 2 Light features

  • Adjustable beat frequency: sets the frequency for the beat detection.
  • Always on top switch: to stay on top.
  • BPM counter
  • AGC - Automatic Gain Control:

Version 1.0.0.8 (Beta) and later

  • ATC - Auto Treshold Control: This can help for better beat detection. Default: Off, can be switched on.
  • ABC - Auto Beat decay Control: For an automatic more stable beat trigger output. This control works with info from the BPM counter. Default: Off, can be switched on.
  • Beat multiplier: The beat multiplier allows you to send up to four “virtual” beats to freestyler when every real beat is detected. You can use this if you have more than one step in a sequence you want to execute when one beat is detected. the four blue lights on the right of the Beat button indicate the status.
  • Sequence restarter: When using the beat multiplier there is an option to restart selected sequences to step 1 when a real beat is detected. This allows flashing of strobes or other fixtures on the beat.
  • Beat Flash: This allows the user to assign one or more override buttons in S2L to control. Every beat the override button is pressed. This allow users to simple flash lights tot the beat without having to use the multiplier and multi step sequences. Flash duration can be set in msec from 100 to 10000 msec.
