Converting MP3 to Constant Bit Rate

Light-O-Rama's Sequence Editor requires the audio files to have a constant bit rate (CBR). This means the audio file needs to be a .wav file (always CBR), or an MP3 saved with constant bit rate.

Even though this is documented by Light-O-Rama, people don't realize this until they see their Light-O-Rama sequence out of sync with the music. They will go in and fix it and then it will go out of sync again. A very frustrating experience for anyone who has gone through this.

Luckily, the fix is very easy, just convert the MP3 to CBR.

1. Download & install Audacity. http://audacity.sourceforge.net/

2. Launch Audacity

3. Open the MP3 file

4. Select "Export" from menu-bar, click on the "Options" button, make sure "Constant" is selected and click on "Okay".

4. Install LAME (only has to be done once)

Audacity will pull this from http://lame.buanzo.com.ar

5. Select "Export" from menu-bar, click on the "Options" button, make sure "Constant" is selected and click on "Okay".Bit Rate
