I’ve been trying to add some music to the game I’ve been making. I’ve been trying to use winsound because it allows you to stop a sound mid-way through playing. The problem is that winsound seems unable to locate my sound file. I’ve tried using different modules such as the playsound m…

Sound feature attributeError: ‘rmse’
In using librosa.feature.rmse for sound feature extraction, I have the following: It gives me: What’s the right way to get it? Sample file: https://www2.cs.uic.edu/~i101/SoundFiles/CantinaBand3.wav Answer I am guessing you are running one of the latest librosa. If you check the changelog for the 0.7, yo…
How to mute/unmute sound using pywin32?
My searches lead me to the Pywin32 which should be able to mute/unmute the sound and detect its state (on Windows 10, using Python 3+). I found a way using an AutoHotkey script, but I’m looking for a pythonic way. More specifically, I’m not interested in playing with the Windows GUI. Pywin32 works…
Extracting F0, jitter and shimmer from an audio file using Python
Recently I got the task: to extract such features as F0(fundamental frequency), Jitter and Shimmer from a given chain of short audio files (around 5-10 sec, a voice singing on one note). And, unfortunately, I am good for nothing in Audio Signal Processing. Any Python libs to help me do it easy and fast? Thank…
Why spectrogram from librosa library have twice the time duration of the actual audio track?
I am using the following code to obtain Mel spectrogram from a recorded audio signal of about 30 s: Obtained spectrogram: Mel spectrogram Can you please explain me why the time axis depicts twice the time duration (it should be 30 s). What is going wrong with the code? Answer You need to pass the sampling rat…
Scipy.signal.spectrogram output lengths
I am trying to analyze the frequencies of a song at certain points of time held inside an array. I am using the scipy.signal.spectrogram function to generate those frequencies. the length of the song is 2:44, or 164 seconds, and the sampling rate of the scipy.wavfile read is 44100. When I use spectrogram: The…
Split audio files using silence detection
I’ve more than 200 MP3 files and I need to split each one of them by using silence detection. I tried Audacity and WavePad but they do not have batch processes and it’s very slow to make them one by one. The scenario is as follows: split track whereas silence 2 seconds or more then add 0.5 s at th…
Create a wav file from blob audio django
On the client side, I am sending a blob audio (wav) file. On the server side, I am trying to convert the blob file to an audio wav file. I did the following: I thought that converting the blob would be similar to converting a blob image to a jpeg file, but was very incorrect in that assumption. That didn̵…
How to call audio plugins from within Python?
I’ve noticed that some open source DAWs such as Ardour and Audacity are able to access audio plugins (e.g. VST, AU) that the user has installed on their system. This makes me think that “there ought to be a way” to do this in general. Specifically, I’d like to call some plugins from wi…
Python bindings for libVLC – cannot change audio output device
VLC 2.2.3, python-vlc 1.1.2. I have a virtual audio output and am trying to get libVLC to output on it. So far, I can see the virtual output appearing in libVLC, but selecting it makes audio play on the default output (i.e. the speakers). This is the relevant part of what I have: I’ve run the code multi…
