SineSubtraction¶

Inputs¶

• frame (vector_real) - the input audio frame to subtract from

• magnitudes (vector_real) - the magnitudes of the sinusoidal peaks

• frequencies (vector_real) - the frequencies of the sinusoidal peaks [Hz]

• phases (vector_real) - the phases of the sinusoidal peaks

Outputs¶

• frame (vector_real) - the output audio frame

Parameters¶

• fftSize (integer ∈ [1, ∞), default = 512) :

  the size of the FFT internal process (full spectrum size) and output frame. Minimum twice the hopsize.

• hopSize (integer ∈ [1, ∞), default = 128) :

  the hop size between frames

• sampleRate (real ∈ (0, ∞), default = 44100) :

  the audio sampling rate [Hz]

Description¶

This algorithm subtracts the sinusoids computed with the sine model analysis from an input audio signal. It ouputs an audio signal.

Source code¶

• C++ source code

• C++ header file
