smst.utils.residual module

smst.utils.residual.subtract_sinusoids(x, N, H, sfreq, smag, sphase, fs)

Subtracts sinusoids from a sound.

Parameters:

• x – input sound
• N – FFT size
• H – hop size
• sfreq – sinusoidal frequencies
• smag – sinusoidal magnitudes
• sphase – sinusoidal phases

Returns:

xr: residual sound

smst.utils.residual.subtract_sinusoids_with_stochastic_residual(x, N, H, sfreq, smag, sphase, fs, stocf)

Subtracts sinusoids from a sound and approximate the residual with an envelope.

Parameters:

• x – input sound
• N – FFT size
• H – hop size
• sfreq – sinusoidal frequencies
• smag – sinusoidal magnitudes
• sphase – sinusoidal phases
• fs – sampling rate
• stocf – stochastic factor, used in the approximation

Returns:

stocEnv: stochastic approximation of residual
