示例1: Spectrum
# 需要导入模块: from pattern import Pattern [as 别名]
# 或者: from pattern.Pattern import play [as 别名]
class Spectrum(PyoObject):
"""
Spectrum analyzer and display.
Spectrum measures the magnitude of an input signal versus frequency
within a user defined range. It can show both magnitude and frequency
on linear or logarithmic scale.
:Parent: :py:class:`PyoObject`
:Args:
input : PyoObject
Input signal to process.
size : int {pow-of-two > 4}, optional
FFT size. Must be a power of two greater than 4.
The FFT size is the number of samples used in each
analysis frame. Defaults to 1024.
wintype : int, optional
Shape of the envelope used to filter each input frame.
Possible shapes are :
0. rectangular (no windowing)
1. Hamming
2. Hanning
3. Bartlett (triangular)
4. Blackman 3-term
5. Blackman-Harris 4-term
6. Blackman-Harris 7-term
7. Tuckey (alpha = 0.66)
8. Sine (half-sine window)
function : python callable, optional
If set, this function will be called with magnitudes (as
list of lists, one list per channel). Useful if someone
wants to save the analysis data into a text file.
Defaults to None.
.. note::
Spectrum has no `out` method.
Spectrum has no `mul` and `add` attributes.

>>> a = SuperSaw(freq=[500,750], detune=0.6, bal=0.7, mul=0.5).out()
