>Bits are dynamically allocated to signal content. If little signal content is availaible beyond 20kHz little bit space is used and the remaining bits get allocated to signals having a higher 'priority'.<

Thank you for agreeing with my point - a lossy coder with 48kHz response is pointless - being able to assign bits as required only underlines that point.

>The extension stream is additional data the term extension doesn't imply that it's used for the upper frequency range only.<

No - the DTS 96/24 is split in half as I explained at least once already.

Oh, and if you're still in doubt about upsampling:

"To decode a core+extension bit-stream, Figure 1 B), the unpacker first separates the stream into the core and extension data. The core decoder decodes the core data and produces the core LPCM audio that is next up-sampled to 96kHz using the 48-to-96kHz interpolator. The core decoding and interpolation are both performed in the “Reconstruct Core Audio Components” block."

What part of this do you not understand? Sheesh...
