pydub

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) You can use: sound = AudioSegment.from_file(…) sound = sound.set_frame_rate(16000) 来源： https://stackoverflow.com/questions

I'm aware of the following question: How to create a pydub AudioSegment using an numpy array? My question is the right opposite. If I have a pydub AudioSegment how can I convert it to a numpy array? I would like to use scipy filters and so on. It is not very clear to me what is the internal structure of the AudioSegment raw data. Pydub has a facility for getting the audio data as an array of samples , it is an array.array instance (not a numpy array) but you should be able to convert it to a numpy array relatively easily: from pydub import AudioSegment sound = AudioSegment.from_file("sound1

I have a problem with Pydub module running in Windows and Linux. When I try open a mp3 file thus: from pydub import AudioSegment sound = AudioSegment.from_mp3("test.mp3") Console show me the next message: WindowsError: [Error 2] The system can not find the file specified But...I have the file (test.mp3) in the same folder that the script, the name is correct. Why I have this problem? (In Linux, have the same error) Make sure that you have ffmpeg http://www.ffmpeg.org/ installed. You can get help from this official page . Other thing that I can think of is that ffmpeg is installed and is in

I'm new in python and i'm using pydub modules to play mp3 track. Here is my simple code to play mp3: #Let's play some mp3 files using python! from pydub import AudioSegment from pydub.playback import play song = AudioSegment.from_mp3("/media/rajendra/0C86E11786E10256/05_I_Like_It_Rough.mp3") play(song) When i run this program, it says: */usr/bin/python3.4 /home/rajendra/PycharmProjects/pythonProject5/myProgram.py /usr/local/lib/python3.4/dist-packages/pydub/utils.py:161: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work warn("Couldn't find ffmpeg or avconv

Ok, now I am stuck up in converting mp3 to wav. I have seen different answers but i think i would to go for the one of pydub, which i already did using these few lines from pydub import AudioSegment AudioSegment.from_mp3("/input/file.mp3").export("/output/file.wav", format="wav") but when I run the above code, i get the following error C:\Python27\lib\site-packages\pydub-0.14.2-py2.7.egg\pydub\utils.py:165: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work Traceback (most recent call last): File "C:/Users/phourlhar/Desktop/VoiceDetector/yeah.py", line 7,

How can I remove the silence from the beginning and the end of wave files with PyDub? I guess I should access segment by segment and check whether it's silent or not (but I'm not able to do it) :/ e.g. I have a wave file with silence at the beginning, end, or both (like below) and I want to remove the silence at the beginning and at the end of the file: e.g. I want to import it sound = AudioSegment.from_wav(inputfile) cycle for every sample of sound to check whether it's silent and mark the last silent sample since when the waves starts (marker1), then get to the last sample before the wave

I have two scripts, one of them splits audio of a certain length, the other one splits audio on every time there is a silent passage. Would it be possible to split the audio on silence, but only after a certain time passed? I would need chunks of videos split on silence which are not shorter than 5 minutes. Splitting script with ignores silence: from pydub import AudioSegment #from pydub.utils import mediainfo from pydub.utils import make_chunks import math #lac_audio = AudioSegment.from_file("Kalimba.mp3", "mp3") #flac_audio.export("audio.mp3", format="mp3") myaudio = AudioSegment.from_file(
