XDSP
This is an implementation of the legacy DirectX SDK utility header DSP math functions using DirectXMath.
See this blog post for more details.
All functions are in the C++ namespace XDSP.
All memory buffers used with these functions must be 16-byte aligned. This happens by default for x64, but requires alignment or use of __aligned_malloc with x86 or ARM.
-
FFT - Fast Fourier Transform with an arbitrary number of samples.
-
FFT4 - Four sample Fast Fourier Transform.
-
FFT8 - Eight sample Fast Fourier Transform.
-
FFT16 - Sixteen sample Fast Fourier Transform.
-
FFTInitializeUnityTable - Initializes unity roots lookup table used by Fast Fourier Transform functions (
FFT,FFTDeinterleaved, andFFTInterleaved) -
FFTPolar - Converts complex components to polar form.
-
FFTUnswizzle - Arranges Fast Fourier Transform function output by order of increasing frequency.
-
Interleave - Interleaves audio samples.
-
Deinterleave - Deinterleaves audio samples.
-
FFTInterleaved - Fast Fourier Transform, plus deinterleaves multichannel audio before processing.
-
IFFTDeinterleaved - Fast Fourier Transform, plus interleaved multichannel audio.
