About Audio Effects
Last updated: June 2026
OptiPix Audio Effects adds professional audio effects to your files directly in the browser. Apply reverb (room, hall, cathedral, plate), delay/echo with adjustable feedback, pitch shift without speed change, audio reversal, distortion, chorus, and flanger effects. Control dry/wet mix for each effect. Preview effects in real-time with A/B comparison. Download with effects permanently applied. Uses Web Audio API ConvolverNode for reverb, DelayNode for echo, and WaveShaperNode for distortion.
How It Works
Effects use Web Audio API nodes: ConvolverNode with synthetic impulse responses for reverb, DelayNode with feedback for echo, WaveShaperNode for distortion, and BiquadFilterNode chains for chorus/flanger. The processed signal is captured via OfflineAudioContext for download.
