Hi Pavel,
Thanks for the reference to your previous discussion and the patches.
They were super helpful. As you can see from my reply to Takashi, I'm
proposing adding a convert_s32 method that doesn't impose dependency
on a HW FPU on alsa-lib. The convert_s32 method would operate on an
array of int32's.
From the point of view of the plugin developer, the change from
convert_s16 to convert_s32 is pretty trivial. The plugins that I
personally care about operate internally with floats. The plugin
would remain responsible for converting between int32 and float.
Sounds much better than my attempt at float API.
I agree that a libsoxr plugin would be great. Getting higher quality
real-time resampling is my ultimate goal :)
If you make it work, you will be praised by countless users :-)
But the existing rate API will have to be modified since libsoxr behaves
a bit different to speex or libresample - see the library author
discussing the issues

Thanks,
Pavel.
