[in] The log base 2 of the FFT length in samples. uLog2Length must be greater than or equal to 2.
# Remarks
The FFT functions generate output in bit-reversed order. Use FFTUnswizzle to rearrange FFT function output into order of increasing frequency.
The FFT functions generate output in bit-reversed order (we use a split-radix FFT radix 4 and 2). Use FFTUnswizzle to rearrange FFT function output into order of increasing frequency.
All buffer parameters must be 16-byte aligned. Audio data must be 32-bit float mono.
