    Capture system audio ("What-U-Hear")

    I experimented and tested considerably with this (capturing output devices on Chrome and Chromium). There are several ways to achieve the requirement in the linked GitHub repostories. I use Native Messaging to capture audio output to speakers and headphones, and/or specific sink inputs I wrote the same algorithm for a Native Messaging host in Python, Bash, C, C++, Node.js, Deno, QuickJS - for the people!


    Chrome Developers

    Keep in mind that getDisplayMedia() does not capture all audio output to speaker or headphones, e.g., does not capture window.speechSynthesis.speak() output, which is not output via the Tab audio, see

  • Appwrite

    Appwrite - The Open Source Firebase alternative introduces iOS support. Appwrite is an open source backend server that helps you build native iOS applications much faster with realtime APIs for authentication, databases, files storage, cloud functions and much more!
