如何在python中将音频文件（wav格式）拼接为1秒的拼接？

如何在python中将音频文件（wav格式）拼接为1秒的拼接？

它真正的简单易用的pydub模块，其详细信息在此处和此处

pydub有一个make_chunks您可以chunk length在中指定的方法milliseconds。

make_chunks(your_audio_file_object, chunk_length_ms)

这是将wav文件拆分为一秒的工作代码。我有一个8.5秒的文件，所以程序创建了9个1秒的块playable。最后一块将较小，具体取决于音频持续时间。

from pydub import AudioSegmentfrom pydub.utils import make_chunksmyaudio = AudioSegment.from_file("myAudio.wav" , "wav") chunk_length_ms = 1000 # pydub calculates in millisecchunks = make_chunks(myaudio, chunk_length_ms) #Make chunks of one sec#Export all of the individual chunks as wav filesfor i, chunk in enumerate(chunks):    chunk_name = "chunk{0}.wav".format(i)    print "exporting", chunk_name    chunk.export(chunk_name, format="wav")
