You can save WAV files with compression such as MPEG (the same compression method as MP3 files). Carrara simply won't import them.

PCM (pulse-code modulation) refers to the sampling method which is the way that an analogue sound signal (which is has continuos pitch variations) is converted to digital (which has stepped pitch variations). The higher the sampling rate and the greater the quantization, the better the sound quality. But that's nothing to do with compression which reduces file size by removing redundancy [the sounds you can't hear or that are repeated in such a way that they can be stored in fewer bits].
