Cinema DTS - main thread

This makes no sense. Coherent Acoustics is a completely different codec to APT-X100 and is lossy in a different way, so you're essentially layering two lossy processes over each other. Encoding lossless is the only thing that makes sense to prevent any further loss, since sadly it's not possible to include the raw APT-X100 data in an mkv or similar.

I want to add that FLAC happens to compress Cinema DTS (APT-X100) data very very well, so well in fact that it often is close to the size you would have with the lossy Coherent Acoustics, or in some cases maybe even smaller.

You can argue that the loss cannot be heard, but we're talking restoration and preservation here. What if someone down the line wants to process the data further and cannot find the original APT-X100 data? Then he has to work with double-lossy-encoded.

Among encoders in general it is looked down upon to encode lossy to lossy, for what it's worth.

If Hollywood aims to preserve audio fidelity by including lossless audio on Blu Rays, why shouldn't we aim to preserve audio fidelity in a similar way? "It's already imperfect, so it can't hurt making it even worse" is not a good argument at all in my eyes. In fact, I'd argue the reverse and say the *only* justification for ever doing a lossy audio encode is when the source is lossless, since you end up with only a single pass of encoding.

thank u sir
