audioflux.chirp
- audioflux.chirp(fmin, fmax, duration, samplate=32000, phi=None, method='logarithmic')
chirp signal
The chirp sweeps from frequency
fmintofmax(in Hz).- Parameters
- fmin: float
initial frequency
- fmax: float
final frequency
- duration: float
output duration in seconds.
- samplate: int
desired sampling rate of the output signal
- phi: float, optional
Phase offset, in radians.
If None, use 1 / 2 * -np.pi.
- method: str
linear, quadratic, logarithmic, hyperbolic
