wav

问题 I've succesfully used ffmpeg in Python to convert mp3-files into wav so I can post them to Google Speech-To-Text. Now I have same situation with webm files and the old function I have doesn't work. It should convert the file into wav and split it into 15 second chunks. Can I do this from webm -file or do I need to convert it first into some other format? The function I've used: def convert_and_split(filename): command = ['ffmpeg', '-i', filename, '-f', 'segment', '-segment_time', '15', '-c',

问题 i'm trying to use librosa to generate some data by cutting 1s pieces from some .wav file with a duration of 60s. This part works, i create all my files and i can also listen to them via any player, but if i try to open them with librosa.load i receive this error: >>> librosa.load('.\\train\\audio\\silence\\0doing_the_dishes.wav', sr=None) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\Users\gionata\AppData\Local\Programs\Python\Python36\lib\site\packages

问题 I'm working in Python 3.6 under Linux Ubuntu and I used the Scapy lib to extract data from a bin file which contained the following stack: IP/UDP/RTP. The RTP-PAYLOAD TYPE is 107 (dynamic), a=rtpmap:107 AMR-WB/16000/1. I put it into a file in raw format and I called it src.aud , but it also wouldn't be a problem to put write it in hex. Now what do I have to do exactly to transform it into audio data format like .wav or .mp3 for example, which is on every computer? I've already made an' effort
