DTS @ 1103kbps = nonsense (or not) ?

[El Heggunte]

Wikipedia says:

In theatrical use, a proprietary 24-bit timecode is optically imaged onto the film. An LED reader scans the timecode data from the film and sends it to the DTS processor, using the timecode to synchronize the projected image with the DTS soundtrack audio.The multi-channel DTS audio is recorded in compressed form on standard CD-ROM media at a bitrate of 1,103 kbit/s.

BUT it also says:

The audio compression used in the theatrical DTS system (which is very different and completely unrelated to the home Coherent Acoustics-based DTS Digital Surround format) is the APT-X100 system. Unlike the home version of DTS or any version of Dolby Digital, the APT-X100 system is fixed at a 4:1 compression ratio.

which means, (176.4x5)kbps = 882kbps

First of all wikipedia isn't always 100% accurate.

Second of all:

The multi-channel DTS audio is recorded in compressed form on standard CD-ROM media at a bitrate of 1,103 kbit/s.

I would surmise that the cdrom world has different limitations than a dvd with just dts audio on it. I'm sure there is some mathmatical formula for what spinning rate is required for a given bitrate.

I do have a dts audio cd - a POLICE collection cd. Its ok but I havent' listened to it in forever. I don't really sit and listen to music in my movie room (well the living room but that is where my surround system is).

Well, I just would like to know where that misinformation (1103kbps) came from. Not sure if the one who wrote it was actually trolling , OR if he/she was simply repeating false information that he/she accepted as "truthful".

Anyway: CDs with 5.1 music in DTS *Coherent Acoustics* are compressed at 44.1kHz at 1234.8kbps
With SPDIF-padding, the result is a "normal" 16-bit stereo PCM stream "full of noise"

EDIT:

I've just updated that article, let's hope it won't be reverted by a self-appointed "watchdog"
