如何在python中将音频文件(wav格式)拼接为1秒的拼接?
我正在寻找一个python函数,将音频文件(wav格式)拼接为1秒持续时间的拼接,并将每个新拼接(持续时间为1秒)存储到一个新的.wav文件中。
回答:
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_chunks
myaudio = AudioSegment.from_file("myAudio.wav" , "wav")
chunk_length_ms = 1000 # pydub calculates in millisec
chunks = make_chunks(myaudio, chunk_length_ms) #Make chunks of one sec
#Export all of the individual chunks as wav files
for i, chunk in enumerate(chunks):
chunk_name = "chunk{0}.wav".format(i)
print "exporting", chunk_name
chunk.export(chunk_name, format="wav")
