Re: [alsa-devel] Support for floating point controls?

Which hardware supports these 32 bit float controls?

For our (http://audioscience.com/internet/products/sound_cards/soundcards.htm) cards, none officially yet.

However, we are working on extensions to our control protocol that allows float parameters, which naturally express the parameters of some of the controlled algorithms on the card/boxes. (The processor on the cards is a floating point DSP)

It would then be a pain if ALSA did not support float controls, because we'd have to convert from float to int in the kernel to pass to userspace, where probably it would need to be rescaled to int again...
