Wave Shifter - Audio Effects Suite for Music & Video

Description

Real-time browser audio processing with pitch shifting, EQ, reverb, dynamics, surround, speed control and more. Wave Shifter is a free and open-source real-time audio processing suite for Chromium-based browsers. It lets you transform the sound of videos, music, live streams and other HTML5 media directly in your browser. Unlike simple playback speed extensions, Wave Shifter provides a complete set of real-time audio effects. Change pitch without affecting speed, enhance audio with professional effects, or build entirely new soundscapes using a flexible layer-based processing system. All audio processing happens locally on your device using the Web Audio API and AudioWorklets. Your audio never leaves your browser. ━━━━━━━━━━━━━━━━━━━━━━ 🎵 Pitch & Playback • Pitch shifting from -12 to +12 semitones • Fine pitch adjustment in cents • Playback speed control • Optional pitch preservation • Smart Processing mode • Adjustable processing block size ━━━━━━━━━━━━━━━━━━━━━━ 🎚 Audio Effects & Mastering • Volume Boost • Effects Mix (precise balance between original and processed sound) • 10-Band Equalizer with a built-in real-time frequency visualizer • Convolution Reverb with Ambience, Chamber, Hall, Plate and Space presets • Dynamic Range Compressor with Threshold, Knee, Ratio, Attack and Release controls • SRS WOW-Inspired Stereo Suite: Stereo Width (SRS 3D interpretation) Stereo Center control Stereo Focus • Left/Right Channel Balance • Bass Enhancement (Subbass generator & Warmth saturator) • Clarity / Definition Exciter ━━━━━━━━━━━━━━━━━━━━━━ 🎛 Creative Effects Create unique sound signatures by combining multiple real-time effects. 🎸 Lo-Fi Effects • Distortion • Bitcrusher • CD Skipper • Vinyl Simulator ⏱ Delay • Stereo Ping-Pong Delay • Adjustable Time • Feedback • Wet/Dry Mix 🎹 Modulation Effects • Chorus • Flanger • Phaser • Tremolo • Vibrato • Rotary Speaker • Ring Modulator • Vowel Filter • Auto Panner • Auto Filter Effects can be layered, chained and mixed to create everything from subtle enhancements to completely transformed audio. 🔄 Overlay Mode • Run multiple effect presets simultaneously on the same audio source • Independent volume control for each preset in the overlay chain ━━━━━━━━━━━━━━━━━━━━━━ 🎬 Surround • Experimental Dolby Surround (5.1) Upmix Expand stereo audio into a virtual surround sound field on supported systems. ━━━━━━━━━━━━━━━━━━━━━━ 🌐 Browser Integration • Works with HTML5 audio and video on virtually any website • Supports popular web audio libraries including Howler.js • Automatically detects dynamically created media elements • Automatically reconnects when websites replace media elements during playback • Configurable website blacklist with wildcard support ━━━━━━━━━━━━━━━━━━━━━━ ⚙ Intelligent Compatibility Wave Shifter automatically adapts to browser security restrictions.
