I am using Python, and I want to analyze audio files from internet streaming media (for example Youtube, Soundcloud, etc.)
Is there a universal way to do so? There is a pre-loading for every music or video, there must be a way to access it? How?
I want to run this script on an external server, that might be relevant to the answer.
Thanks
All sound you "hear" on your pc has to run through your soundcard, Maybe somehow write a script that "records" the sounds runnning through the device. Maybe u can use Pymedia module?

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'm working on a python3 project (in PyCharm, using Windows 10) and I'm trying to play a series of tones and save them all to a mp3 file.
I can get it to play a series of notes with winsound:
import winsound
while True:
winsound.Beep(1000, 1000)
But I can't save it.
All help appreciated!
If you want to save output to a file, rather than just play it, probably the most ideal way of doing this is to generate midi files. There are a few packages that can help you create midi files in a similar way.
This example uses the package called mido
from mido import Message, MidiFile, MidiTrack
mid = MidiFile()
track = MidiTrack()
mid.tracks.append(track)
track.append(Message('note_on', note=64, velocity=64, time=32))
mid.save('new_song.mid')
You can convert midi files to MP3s easily if needed (many programs or even online tools can do this) although, midi files are generally well-supported in most applications.

Although perhaps dated, you can also check the PythonInMusic wiki for references to more MIDI and other audio libraries.
Alternatively, you can use a separate program to record your audio output when running your python script using winsound.
i need to handle a lot of files and i dont want to worry about their filenames etc.
So the idea is i sent a file Test.png to an external db/rest api etc. with python and i am getting back an uuid for this file.
The next time my script does need this file it calls this external services with uuid and does get back this file :)
It does sound like amazon s3 ;) But i need something running on linux (what i would prefer) or windows and it should be open source. I dont need something special and very easy to use (out of the box). Oh and no big data solution, the amount of data would be around 5 gb
My file processing language is Python 3.6
Does someone know a good solution here?
thanks
After days of search, i found something :) I want to share this:
https://minio.io/
Object Storage, can be ran inside docker etc. and has a client library for python, just perfekt for me :)
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.
I'm working on an audio mixing program (DAW) web app, and considering using Python and Python Gstreamer for the backend. I understand that I can contain the audio tracks of a single music project in a gst.Pipeline bin, but playback also appears to be controlled by this Pipeline.
Is it possible to create several "views" into the Pipeline representing the project? So that more than one client can grab an audio stream of this Pipeline at will, with the ability to do time seek?
If there is a better platform/library out there to use, I'd appreciate advice on that too. I'd prefer sticking to Python though, because my team members are already researching Python for other parts of this project.
Thanks very much!
You might want to look at Flumotion (www.flumotion.org). It is a python based streaming server using GStreamer, you might be able to get implementation ideas from that in terms of how you do your application. It relies heavily on the python library Twisted for its network handling.
