CEI .wav Files are .wav files that contain usually between 4 - 6 tracks of audio and Data.
These files can also be in other formats such as .wma and .wmv for videos. These are then played through a 5.1 channel USB sound card which connects to some speakers and either a Grey Box or a Layton Bitstripper. The Showtape Audio is also DBX Decoded meaning you don't need a DBX Decoding Box. You will require a waveshaper to use the showtape with a Grey Box or a Layton Bitstripper.
Files are formatted two different ways, one with four tracks of audio, and one with six tracks of audio. The formatting for the 4-track .wav is as follows:
- Track #1 contains the show audio. If the track is stereo, it will be the left channel.
- Track #2 contains the show audio. If the track is stereo, it will be the right channel.
- Track #3 contains the Pianocorder Formatted Biphase Mark Code. This usually contains the Top Drawer Data for the show.
- Track #4 contains the Pianocorder Formatted Biphase Mark Code. This usually contains the Bottom Drawer Data for the show.
The format for a 6 track .wav file is similar to the 4-track .wav. In this format, the contents usually in tracks 3-4 are placed in tracks 5-6, while 3-4 remain unused and silent.
