Audio Recorder - Tab Audio & Voice Capture

Record tab audio, microphone voice, or both in MP3 & WAV without muting speakers. Built-in audio trimmer & 100% local privacy.

Capture studio-quality digital audio directly inside your browser. Audio Recorder gives you complete control over browser tab audio capture, microphone recording, and dual-source audio mixing without subscriptions or time limits. HEAR EVERYTHING WHILE RECORDING Legacy audio capture extensions suffer from a frustrating design flaw: the moment you hit record, they mute your active tab, cutting off your headphones and speakers. Audio Recorder features a zero-mute pass-through architecture built on the native Web Audio API. When you record a webinar, video conference, live stream, or music track, the sound routes seamlessly back to your output device so you can listen comfortably in real time. DUAL-ENGINE MIXING: TAB SOUND AND YOUR VOICE Whether you need internal audio or voiceover commentary, Audio Recorder adapts to your recording scenario: Capture pure tab audio: Record crystal-clear internal computer sound directly from any webpage, avoiding background room noise or accidental microphone interference. Record your voice: Use your external or built-in microphone with hardware-accelerated noise suppression and echo cancellation for voice notes, podcasts, and dictation. Simultaneous dual mix: Combine tab sound and microphone input in real time. Independent volume controls allow you to boost tab sound up to 200% or balance your voice over background audio, creating balanced recordings for tutorials, interviews, and presentations. UNCOMPRESSED WAV PCM AND OPTIMIZED WEBM OPUS Export your recordings in formats tailored for professional editing or lightweight sharing: WAV 16-bit Linear PCM: True uncompressed, studio-grade audio with a canonical RIFF header. Perfect for music producers, video editors, and audio engineers who demand zero loss in acoustic fidelity. WebM Opus 192 kbps: Efficient, high-bitrate compression for everyday recordings. Every file includes injected EBML duration metadata, ensuring smooth seeking, scrubbing, and timeline navigation in VLC, QuickTime, and video editors without playback freezes. REAL-TIME VISUALIZATION AND LOCAL AUDIO LIBRARY Monitor your recording session with a smooth 60 FPS Canvas spectrum visualizer and responsive VU meters. After recording, manage your files directly within the built-in library. Play back captures in the integrated HTML5 player, inspect file sizes and timestamps, and download tracks with clean, descriptive filenames in one click. CLIENT-SIDE SECURITY AND ABSOLUTE PRIVACY Your audio never leaves your machine. Audio processing, encoding, and file generation take place 100% locally on your computer. There are no remote audio uploads, no background tracking scripts, no third-party analytics, and no 5-minute recording paywalls. To open the recorder or start capturing instantly from any webpage, press Alt+R (Option+R on macOS) or click the extension icon in your browser toolbar.
