Aussi, pour moi le terme Lossless lu ici ou là est abusif.

C'est effectivement le cas.
Un algorithmie efficace pour la gestion sous la barre des 32 bits.

Sur un autre forum, Jussi (développeur de HQP) est un peu plus dur mais en raison du buzz (je pense).

Citation :There is nothing special in the LeedH volume control, I find it pretty funny if it really is granted a patent somewhere. Quite typical though, explain a simple thing in very complex way to make it sound complex and fancy and in a way fool the application examiner (and anybody trying to read it), such happens a lot in patent field. But it is notable that it doesn't work when you have any other DSP involved that produces samples that have higher precision than the original integer samples. So the integer way they do volume control means that it is useless for example when upsampling, digital room correction, eq, headphone processing or any other DSP is involved.
 
The way they do volume control with integer data is nothing new and it works only when you have max 24-bit input, do volume control and have 32-bit output. Nothing else. Volume control range is the amount of extra headroom you have due to extra number of bits.
