The soundtrack alone is over 4 hours of audio, and I'm sure the speech is significantly more than that.
Maybe you meant compressed, but with a lossless codec? Citation? =)

CMI does have uncompressed audio in a sense, it's set at 22.05Khz instead of 44.1Khz. The bit rate for each track is 705kbps, each track is then heavily "zipped" with it's iMuse cues into an .IMX file, which is then placed into the bundle file. The game simply reads the iMuse cues to know which tracks to cache and playback as Wave through the sound card.
The difference between this and lossless is that it's the games engine doing the compression rather than the actual tracks being compressed into a readable lossless file.
The engine really was a genius bit of work, this method was used in other games such as Sam & Max Hit the Road and Full Throttle but with lower quality Wave files.
Here's a quick example of the size differences of a track that's 2:21 long:
1103-W~1.IMX = 5.12MB
1103-W~1.WAV = 11.8MB
