问题 I'm attempting to join a list of wav files together into one audio file. So far this is what I have. I can't wrap my head around how to sum the objects together though since they are each an object. import glob, os from pydub import AudioSegment wavfiles = [] for file in glob.glob('*.WAV'): wavfiles.append(file) outfile = "sounds.wav" pydubobjects = [] for file in wavfiles: pydubobjects.append(AudioSegment.from_wav(file)) combined_sounds = sum(pydubobjects) #this is what doesn't work of

问题 First of all, here is the link to a similar question to this: Pydub (WindowsError: [Error 2] The system can not find the file specified) Although in this one the problem is with ffmpeg, which I solved by setting the absolute path. After setting the absolute path for converter and/or ffmpeg with either: AudioSegment.converter = r'C:\ffmpeg\bin' or AudioSegment.ffmpeg = r'C:\ffmpeg\bin' I still get this error: C:\Program Files\Python36\lib\site-packages\pydub\utils.py:193: RuntimeWarning:

问题 I have small-sized sound files stored in MongoDB as BSON . Task is to retrieve Binary data from the database, convert it to an appropriate format and send back to the front end. The problem is with the converting. I have found pydub can be used for this. My code is as follows query_param = json_data['retriever'] query_param1 = query_param.replace('"', ""); data = db.soundData y = data.find_one({'name': query_param1}) s = y['data'] // here I retrieve the binary data AudioSegment.from_file(s)

问题 first: I don't know where to put this topic because it's an programming and sound-question. Please comment if it's at the wrong place. But this is my question: How can I load a sound into Python and create the "reverse-sound" of it. So when I play the original and the "pi-shifted" file, they create an destructive interference and cancel each other out so you hear almost nothing. Are there any Libraries to use? Here's a small explanation-video. Thank you a lot. Just want to experiment a little

问题 I find myself in front of a wall here, simply trying to load an audio file into pydub for converting it keeps on throwing a "[Errno 2] No such file or directory" error. Naturally I have spent way too much time making sure the paths were valid, tried relative and absolute paths and confirmed that the python method open() was working fine with the exact same path, which it is. I'm working in ipython 3.2 with python 2.7 via the anaconda 2.3 distrib on ubuntu. from pydub import AudioSegment sound

问题 I have a couple audio files that I open in Pydub with AudioSegment . I want to decrease the audio quality from frame rate 22050 to 16000 Hz. (One channel files) If I simply change the frame rate of AudioSegment, what I get is the exact same wave played in slower speed. Well, fair enough. But how do I actually change the waves to fit a lower quality, same speed playback? (Manual interpolation is the only thing I can think of, but I don't want to get into that trouble) 回答1: You can use: sound =
