Improve resampler filter computation speed Approximate speed improvement is 10-15% for filter computation, which is floating point intensive. This will be important for devices without hw floating point support. Change-Id: I10b4e778c8d632b52218a777504b092c189e437f Signed-off-by: Andy Hung <hunga@google.com>

Improve dynamic audio resampler filter generation Improve dynamic audio resampler filter generation speed by 2x. The resulting filters should be the same (excepting roundoff). Also added check for upsampling sample rate changes to share previously generated filters. Modify the profiling to improve output format and sampling result reliability.

Audio resampler update to add S16 filters This does not affect the existing resamplers. New resampler accessed through additional quality settings: DYN_LOW_QUALITY = 5 DYN_MED_QUALITY = 6 DYN_HIGH_QUALITY = 7 Change-Id: Iebbd31871e808a4a6dee3f3abfd7e9dcf77c48e1 Signed-off-by: Andy Hung <hunga@google.com>
