Asynchronous Audio Source Plugin for OBS Studio

Introduction

This plugin provides a asynchronous audio source to debug audio buffering issues.

I hope this plugin is useful to reproduce and debug the issue. obsproject/obs-studio#4600

Properties

Frequency L, R

The frequency of a sine wave output by this plugin.

Skew

Make audio data a little slower or faster if set to negative or positive, respectively.

• If you set negative value, you will see a short period of silence.
• If you set positive value, you will see a block of dropped samples.
• I recommend to set +/-5000 ppm so that you will see the issue more than 15 times in a minute.

Build and install

Linux

Use cmake to build on Linux. After checkout, run these commands.

sed -i 's;${CMAKE_INSTALL_FULL_LIBDIR};/usr/lib;' CMakeLists.txt
mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_LIBDIR=/usr/lib ..
make
sudo make install

You might need to adjust CMAKE_INSTALL_LIBDIR for your system.

macOS

Use cmake to build on Linux. After checkout, run these commands.

mkdir build && cd build
