smst.utils.synth module

smst.utils.synth.spectrum_for_sinusoids(ipfreq, ipmag, ipphase, N, fs)

Generates a spectrum from a series of sine values, calling a C function.

Parameters:

• ipfreq – sine peaks frequencies
• ipmag – sine peaks magnitudes
• ipphase – sine peaks phases
• N – size of the complex spectrum to generate
• fs – sampling frequency

Returns:

Y: generated complex spectrum of sines

smst.utils.synth.spectrum_for_sinusoids_py(ipfreq, ipmag, ipphase, N, fs)

Generates a spectrum from a series of sine values. Python implementation.

Parameters:

• ipfreq – sine peaks frequencies
• ipmag – sine peaks magnitudes
• ipphase – sine peaks phases
• N – size of the complex spectrum to generate
• fs – sampling frequency

Returns:

Y: generated complex spectrum of sines

smst.utils.synth.synthesize_sinusoid(freqs, amp, H, fs)

Synthesizes one sinusoid with time-varying frequency.

Parameters:

• freqs – frequencies of sinusoids
• amps – amplitudes of sinusoids
• H – hop size
• fs – sampling rate

Returns:

y: output sound
