【KAWAKO】Pydub-某些函数的使用方法

• EQ
  • 源码
  • 其中使用的_eq函数源码
  • 测试代码

EQ

源码

• seg：AudioSegment音频

• focus_freq：需要调整的中心频率

• bandwidth：调整的频率范围

• channel_mode：调整哪个声道

• filter_mode:：滤波器种类。“peak”带通，“low_shelf”对低频做处理，“high_shelf”对高频做处理

• gain_dB：处理的增益大小

• order：暂时没看懂什么意思，保持默认的2就好

其中使用的_eq函数源码

测试代码

抑制高频和低频，略微拉升中频，模拟电话音色。

from pydub import AudioSegment, scipy_effects
 
sound=AudioSegment.from_file("common_voice_zh-CN_22770707.wav","wav")
 
gain = -1.5
aaa = scipy_effects.eq(sound, 500, filter_mode="low_shelf", gain_dB=gain, order=2)
aaa = scipy_effects.eq(aaa, 500, filter_mode="low_shelf", gain_dB=gain, order=2)
aaa = scipy_effects.eq(aaa, 3500, filter_mode="high_shelf", gain_dB=gain, order=2)
aaa = scipy_effects.eq(aaa, 3500, filter_mode="high_shelf", gain_dB=gain, order=2)
aaa = scipy_effects.eq(aaa, 500, filter_mode="low_shelf", gain_dB=gain, order=2)
aaa = scipy_effects.eq(aaa, 500, filter_mode="low_shelf", gain_dB=gain, order=2)
aaa = scipy_effects.eq(aaa, 3500, filter_mode="high_shelf", gain_dB=gain, order=2)
aaa = scipy_effects.eq(aaa, 3500, filter_mode="high_shelf", gain_dB=gain, order=2)
aaa = scipy_effects.eq(aaa, 2000, 1500, filter_mode="peak", gain_dB=5, order=2)
 
aaa.export("qaq测试语音大小(6).wav","wav")
