About

Realtime FX Audio Player for Android (pure Java) built for games and creative tools.

Play MP3/WAV/OGG from assets, raw resources, or any file path, then tweak sound live with smooth sliders: tape-style speed control (slow-motion / pitch change), low-pass filtering for muffled “underwater/behind-wall” vibes, and instant volume automation.

Includes tape pause/resume animations with clean fades, stable streaming output via AudioTrack, and a lightweight DSP pipeline.

Designed to be Sketchware Pro friendly and easy to embed into any project—perfect for retro emulation UI, or dynamic in-game audio effects.
