Floating point implementations in CAPIV2

Hi,

Is it possible to have floating point implementations in CAPIV2? For example in the capi_v2_gain code, can I read in 32-bit floating point values from a raw file and save the result as 32-bit float values? It seems floating point is supported as per the enum data_format_t in 'Elite_CAPI_V2_types.h', but the 'is_supported_media_type' function in capi_v2_gain.c explicitly checks if the data is 'CAPI_V2_FIXED_POINT, and if the data is 16 bits, and only then proceeds for further processing.

What needs to be modified to read in floating point values, process them in floating point and save the result in floating point?

Regards,

Naveen

Why should anyone want to do that? 

​BR,

To compare performances between float and fixed point implementations.
