With this tutorial we are going to learn how to apply Post process Effects to the scene. We are going to adapt one of the materials used in a previous tutorial Transition effects using materials to be able to use it with a post process volume and view the effect in all the scene.
Audio Analyzer is a plugin for Unreal Engine 4 that allow you to visualize the waveform and frequency spectrum of an audio file in real-time. Also can detect the beats of any audio source in realtime by using frequency spectrum analysis (FFT).
You can use in your games or applications and make your games react to the music. It is really easy to configure.
- Amplitude analysis
- Frequency spectrum
- Basic beat tracking
- BPM tracking
- Pitch tracking
- Works with audio .wav files and Microphone input
- Support cooked builds
- Android mobile friendly
- Full source C++ included
- Wav, mp3, ogg, flac supported
- Loopback (What-you-hear) support (Only Windows)
- New Offline analysis (Amplitude sections)
With this tutorial we are going to add a beat tracking widget to our previous spectrum visualizer. We are going to improve this visualizer adding the average bars too and a song selector.
With this tutorial we are going to conclude the series about audio analysis using FMOD library and Unreal Engine 4. This time we are going to explain how to make a simple beat tracker in real-time. This algorithm will not be an universal solution for all the songs but is an aceptable approximation taking into account the process time limitations.
