Detailed Description

Data struct of f32 multi-rate resampler.

This structure is used by a resampler internally. A user should access this structure only in case of extensions for the DSP Library. To initialize the resampler, use the dsps_resampler_mr_init() function. To execute the resampler, use the dsps_resampler_mr_exec() function. To free the resampler, use the dsps_resampler_mr_free() function.
