SlowWave

SlowWave is a creative slow-playback and reverb transformation tool that lets you stretch audio between 0.5x and 1.5x while shaping ambience with "Size" and "Mix" controls. It includes LR peak meters, stereo correlation, and dual-layer FFT for detailed visual feedback.

Drag, slow down, and loop audio instantly — perfect for learning tricky musical passages or creating atmospheric slowed-down textures.

"Fully coded DSP & GUI — optimized for CPU efficiency. No images, no SVGs, no skins. Pure signal."

Standalone Architecture

The standalone architecture enables instant loading, looping, and analysis of audio files without requiring a DAW. It's designed for fast, focused audio work—whether checking references, making precise adjustments, or performing detailed evaluations.

CPU-Efficient Processing

Each tool is engineered with highly optimized DSP and lightweight graphics, ensuring stable, low-latency performance—even under heavy analysis or high sample rates.

File Management & Export

Flexible Loading:

• Load Button: Browse files via your system dialog.
• Drag & Drop: Drag audio files directly onto the window for instant loading.

Audio Export (Disabled in Free Version)
SlowWave allows exporting processed audio files for offline use:
