Framework
Use Accelerate’s discrete cosine transform to remove noise from a signal.
Shape audio output using discrete cosine transforms and biquadratic filters.
class v DSP .DCT
A single-precision discrete cosine transform.
enum v DSP .DCTTransform Type
Discrete cosine transform types.
The functions in the Discrete Cosine Transforms (DCT) family calculate a discrete cosine transform of a specified length on a vector.
func v DSP _DCT _Create Setup(v DSP _DFT _Setup?, v DSP _Length, v DSP _DCT _Type) -> v DSP _DFT _Setup?
Creates a data structure for use with v
to perform a single-precision, discrete cosine transform.
func v DSP _DCT _Execute(Opaque Pointer, Unsafe Pointer<Float>, Unsafe Mutable Pointer<Float>)
Calculates the discrete single-precision cosine transform for a vector.
Shape audio output using discrete cosine transforms and biquadratic filters.
Apply biquadratic filters to single- and multi-channel data.
