Python-生成音乐-pyshnth

Pyshnth

音乐生成模块

乐理

• 声音：物体振动产生，振动次数越多，音越高；振动次数越少，音越低
• 可闻：人耳可以听到的声音在每秒16-2000此左右
• 乐音：振动规则产生，听起来高低明显
• 噪音：振动不规则产生，听起来高低不明显
• 音乐：将声音通过艺术形象表达人们的思想感情
• 音阶：do、re、mi、sol、la、（do）
• 调性：C、D、E、F、G、A、B

安装

pip install pysynth

原装示例

import pypsynth

# Example 1: The C major scale
song1 = [
['c',4],['d',4],['e',4],['f',4],['g',4],['a',4],['b',4],['c5',2],['r',1],
['c3',4],['d3',4],['e3',4],['f3',4],['g3',4],['a3',4],['b3',4],['c4',2],['r',1],
['c1*', 1], ['c2*', 1], ['c3*', 1], ['c4*', 1], ['c5*', 1], ['c6*', 1], ['c7*', 1], ['c8*', 1],
]

pysynth.make_wav(song1, fn = "pysynth_scale.wav")

随机轻音乐

import pypsynth
import random

def randsong():
	D='cdefgab'
	T=range(1, 7)
	R = lambda a,b:random.randint(a,b)
	M = lambda :f'{D[R(0, len(D))]}{R(1,6)}*'
	N = lambda :T[R(0, len(T))]
	song = tuple((M(), N()) for i in range(32))
	print(song)
	pysynth.make_wav(song,fn =r"song.wav")

randsong()
