AI Audio Enhancer — Professional Audio Enhancement in Your Browser
Transform your audio recordings with our free AI-powered audio enhancer. Featuring a dual-engine architecture — a GTCRN neural network for intelligent AI enhancement and native Web Audio API DSP for lightning-fast processing — this tool delivers studio-quality audio improvement entirely in your browser. No uploads, no accounts, no subscriptions. Your audio stays 100% private on your device.
Dual-Engine Architecture: AI + DSP
What makes this enhancer unique is its dual-engine approach. The AI Engine uses GTCRN (Grouped Temporal Convolutional Recurrent Network), a state-of-the-art neural network from ICASSP 2024 with only 48,000 parameters. Despite its tiny size (~200 KB download), GTCRN outperforms RNNoise and delivers professional-grade audio enhancement. It processes audio frame-by-frame through the neural network, intelligently boosting clarity while preserving natural sound characteristics.
The DSP Engine uses your browser's built-in Web Audio API nodes — BiquadFilterNode for precise frequency shaping, DynamicsCompressorNode for volume dynamics control, and GainNode for level normalization. This engine requires zero downloads and processes audio almost instantly, making it perfect for quick enhancements when speed is the priority.
Four Professional Presets for Every Scenario
Choose from four carefully designed presets, each tailored for specific use cases. Voice Clarity applies a highpass filter at 80 Hz to remove rumble, boosts the presence range (2-5 kHz) where consonants live, applies gentle de-essing, and normalizes volume — perfect for podcasts, interviews, voice memos, and conference calls. Music Enhance adds warm bass shelving at 200 Hz, presence lift at 3.5 kHz, and an air shelf at 12 kHz with gentle limiting — ideal for songs, field recordings, and music demos.
Loudness Boost uses aggressive dynamic compression with heavy makeup gain and brick-wall limiting, bringing quiet recordings up to broadcast-ready levels. Custom EQ gives you a full 10-band graphic equalizer spanning from 31 Hz to 16 kHz, plus compression and peak normalization, putting complete control in your hands for any audio scenario.
10-Band Graphic Equalizer
The Custom EQ mode provides professional-grade frequency control with ten bands: 31 Hz, 63 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 4 kHz, 8 kHz, and 16 kHz. Each band offers ±12 dB of adjustment using parametric peaking filters (with shelving at the extremes). Combined with automatic compression and peak normalization, this equalizer gives you the same tools that professional audio engineers use — completely free and running locally in your browser.
Bulk Processing with Before/After Preview
Drop multiple files at once and process them sequentially with full progress tracking. Every enhanced file includes a side-by-side before/after audio player so you can hear the improvement instantly. The tool also shows detailed audio analysis including peak level, RMS level, and dynamic range measurements for both the original and enhanced versions. Download individual files or grab everything as a ZIP archive.
100% Private — Zero Server Contact
Unlike cloud-based audio enhancement services that upload your recordings to remote servers, our tool runs everything locally. The GTCRN AI model downloads once (only 200 KB, cached in your browser for future visits) and all subsequent processing happens entirely on your CPU using Web Audio API's OfflineAudioContext and ONNX Runtime Web. Your recordings, podcasts, meeting audio, music demos, and private conversations never leave your device. This makes it the ideal choice for journalists, musicians, podcasters, lawyers, healthcare professionals, and anyone handling sensitive audio content.
Perfect For
Podcasters improving voice clarity and volume consistency. Musicians enhancing demos and rough recordings. Content creators boosting voiceover quality. Students making lecture recordings clearer. Remote workers improving meeting recording quality. Audio engineers needing quick EQ and normalization. Anyone who wants professional audio enhancement without expensive software or cloud subscriptions — completely free, completely private, completely in your browser.
