I have tried using soundmeter for this specific issue, however, did not really find a way to do it so. I want to get the current PC microphone input, and as an output to get the Decibel of the sound that is recorded by my integrated microphone. Any other libraries that you can suggest? Searched a lot, but did not really find something useful.

I'm writing a script that will automatically adjust the audio levels of a program, So I need a way to get audio levels in python. I've looked online for libs to help with this but I was unable to find anything
I'm trying to build a virtual microphone that takes the physical microphone's input stream, modifies the audio using a neural network model written with Python, and replaces the sound stream with my program's output sound stream (in near realtime) so that other apps (e.g. Zoom, Skype, etc.) will receive my app's modified audio stream, for both Mac and Windows.
I've been reading for the last few hours and so far found several libraries that might (?) be able to work here: WebRTC, Soundflower, etc. Does anyone know if there's already a good library that can do or facilitate this? This might be wading into offtopic territory, but if this is doable entirely in Python, e.g. through eel or similar, does anyone know of any library that can do the same type of audio manipulation?
Thank you!
You can create virtual microphone device using official Core Audio APIs
I have a question that feels like it should be simple, but my searches haven’t turned up an answer. Hoping someone can help me narrow down keywords or point me to some documentation.
I have a camera connecting to a computer with an Ethernet cable, the output format is MPEG-2 transform stream. I would like to open this in python and run code on it (for the sake of the example - let’s say display it with some text and a frame counter over it), much like I would usually do with a regular usb webcam and opencv.
Is this a simple matter of syntax, or am I going to be running into bigger problems? Also what are the professional terms for what I’m trying to do that would redirect my search to something more productive? (I’m very much a beginner, feel free to assume I am missing basic info)
I'm trying to write something that catches the audio being played to the speakers/headphones/soundcard and see whether it is playing and what the longest silence is. This is to test an application that is being executed and to see if it stops playing audio after a certain point, as such i don't actually need to really know what the audio itself is, just whether or not there is audio playing.
I need this to be fully programmatic (so not requiring the use of GUI tools or the like, to set up an environment). I know applications like projectM do this, I just can't for the life of me find anything anywhere that denotes how.
An audio level meter would also work for this, as would ossiliscope data or the like, really would take any recommendation.
Here is a very similar question: record output sound in python
You could try to route your output to a new device with jack and record this with portaudio. There are Python Bindings for portaudio called pyaudio and for jack called PyJack. I have never used the latter one but pyaudio works great.
Is it possible to get the system output audio (the exact same thing that goes through the speakers) and analyze it in real time with Python? My intention is to build a sound visualizer. I know that it is possible to access the microphone with pyaudio, but I was not able to access the sound card output in any way, I'm looking for a solution that works on Windows.
Thank you for reading.
Not sure how this project is doing these days, it's been a long time since it's been updated. PyVST allows you to run python code in a VST inside a VST host, which makes it possible to handle realtime audio events.
You might want to look at http://code.google.com/p/pyo/ for some ideas about how to handle DSP data as well.
