music.noise¶
- music.noise(noise_type='brown', duration=2, min_freq=15, max_freq=15000, number_of_samples=0, sample_rate=44100)[source]¶
Return a colored or user-refined noise.
- Parameters:
- noise_type
stror scalar Specifies the decibels gain or attenuation per octave. It can be specified numerically (e.g. ntype=3.5 is 3.5 decibels gain per octave) or by strings: - “brown” is -6dB/octave - “pink” is -3dB/octave - “white” is 0dB/octave - “blue” is 3dB/octave - “violet” is 6dB/octave - “black” is -12/dB/octave but, in theory, is any < -6dB/octave See [1] for more information.
- durationscalar
The duration of the noise in seconds.
- min_freqscalar
in[0, fs/2] The lowest frequency allowed.
- max_freqscalar
in[0, fs/2] The highest frequency allowed. It should be > fmin.
- number_of_samples
integer The number of samples of the resulting sonic vector.
- sample_rate
integer The sample rate to use, by default 44100.
- noise_type
Notes
The noise is synthesized with components with random phases, with the moduli that are related to the decibels/octave, and with a frequency resolution of fs / nsamples = fs / (fs*d) = 1/d Hz
