  1. captureSystemAudio

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

    I have written the same code in C++ https://github.com/guest271314/captureSystemAudio/blob/master/native_messaging/capture_system_audio/capture_system_audio.cpp, Python https://github.com/guest271314/captureSystemAudio/blob/master/native_messaging/capture_system_audio/capture_system_audio.py, and QuickJS (C source code) https://github.com/saghul/txiki.js/issues/294. QuickJS is the only implementation that winds up clipping the end of real-time audio capture.

  3. native-messaging-c

    C Native Messaging host

    I know what the code is doing: processing real-time audio capture and converting the data to a JSON array to send to the browser. I wrote the code from scratch (cobbled together using other peoples' code) in C++ https://github.com/guest271314/captureSystemAudio/blob/master/native_messaging/capture_system_audio/capture_system_audio.cpp and C https://github.com/guest271314/native-messaging-c/blob/main/nm_c.c. I am stuck on the string concatenation is C part.

  4. txiki.js

    A tiny JavaScript runtime

    I have written the same code in C++ https://github.com/guest271314/captureSystemAudio/blob/master/native_messaging/capture_system_audio/capture_system_audio.cpp, Python https://github.com/guest271314/captureSystemAudio/blob/master/native_messaging/capture_system_audio/capture_system_audio.py, and QuickJS (C source code) https://github.com/saghul/txiki.js/issues/294. QuickJS is the only implementation that winds up clipping the end of real-time audio capture.
