OSC Audio Pocket Oscillator Standalone VST3 AU AUv3 WiN macOS

Pocket Oscillator is a compact stereo oscillator plugin and standalone app for Windows and macOS. It generates test tones and basic waveforms—sine, square, saw, and noise—with controls for wave selection, frequency, and volume. A built-in oscilloscope provides visual feedback, making it easy to check signal flow, calibrate gear, or troubleshoot audio paths. The plugin supports VST3 and AU formats, and the standalone version works without a DAW. All parameters are automatable and the resizable interface scales to fit your screen. This tool is aimed at hobby producers, audio tinkerers, and anyone who needs a reliable signal generator for testing speakers, headphones, or modular setups. It’s also handy for quick ear training or adding simple tonal elements to a track. Pocket Oscillator is lightweight (12 MB) and works with FL Studio, Ableton, Logic, and other DAWs that host VST3 or AU plugins. Whether you’re debugging a patch or just need a steady tone, this utility keeps things straightforward.
