转换成mono单声道

from pydub import AudioSegment

# 加载MP3文件
mp3_file_path = r"E:\allchat\output.wav"
audio_segment = AudioSegment.from_mp3(mp3_file_path)

# 转换为单声道
audio_segment = audio_segment.set_channels(1)

# 导出为单声道MP3文件
mono_mp3_file_path = r"E:\allchat\output_1.wav"
audio_segment.export(mono_mp3_file_path, format="mp3")

采样率更改为16000

from pydub import AudioSegment

def resample_wav_with_pydub(input_file, output_file, new_rate):
    # 读取原始WAV文件
    audio = AudioSegment.from_wav(input_file)
    
    # 设置新的采样率
    audio = audio.set_frame_rate(new_rate)
    
    # 导出重采样后的WAV文件
    audio.export(output_file, format='wav')

# 使用示例
resample_wav_with_pydub('input.wav', 'output_16000.wav', 16000)
