High-fidelity Web Audio utility for beatmakers, language learners, and sound designers. Real-time pitch transposition, voice-preserved time stretching, and 16-bit WAV export.
Add to Chrome — FreeSeamless, lightweight tab audio processing right in your Chrome toolbar.
Select Pitch Preserved or Linked Tape Varispeed, then set your target WAV resolution (48kHz, 44.1kHz, or 22.05kHz).
Click the red mic button to start recording active tab audio with a live animated level meter.
Adjust pitch and speed sliders live during playback, then click Stop to download your 16-bit WAV file.
Configure your capture settings in seconds before recording.
Use Pitch Preserved to slow down lectures without changing pitch, or switch to Link Speed & Pitch for authentic vinyl pitch-bending sound design.
Export uncompressed 16-bit WAV files at 48kHz for DAW production, 44.1kHz for CD fidelity, or 22.05kHz for speech & voice memos.
Speed up or slow down audio (0.5x to 2.0x) without altering natural vocal pitch. Essential for language learning and transcription.
Pitch and speed link dynamically for authentic Lo-Fi, Vaporwave, and hardware sampler sound design workflows.
Export samples in uncompressed 16-bit PCM WAV at Studio 48kHz, Standard 44.1kHz, or Speech 22.05kHz resolution.
All time-stretching and pitch resampling run natively in browser memory via the Web Audio API with zero CPU lag.
Capture audio cleanly in any active browser tab while maintaining live playback monitoring.
Zero data collection. Captured audio stays local and is never uploaded to external servers.
Yes, Audio Sampler is 100% free to use with all pitch shift, speed control, and WAV export features fully unlocked.
Yes. Audio Sampler is built on Manifest V3 standards and works seamlessly across all Chromium-based browsers, including Microsoft Edge, Brave, and Opera.
Voice Preserve Mode uses an Overlap-Add (OLA) time-stretching algorithm to alter playback speed while holding vocal pitch steady. Tape/Vinyl mode links speed and pitch dynamically—speeding up raises pitch and slowing down lowers it, mimicking classic hardware samplers.
Audio Sampler exports uncompressed 16-bit PCM WAV files. You can select between Studio Quality (48kHz), CD Quality (44.1kHz), or Radio/Speech Quality (22.05kHz) prior to recording.
Open any browser tab playing audio, click the Audio Sampler extension icon in your toolbar, set your desired pitch/speed adjustments, and click Start Recording.
Yes. Our stream-buffering engine processes audio efficiently via offscreen documents to handle extended capture sessions without freezing or crashing browser memory.
To strictly comply with Chrome Web Store Content Policies, direct capture on restricted video streaming domains is disabled. Audio Sampler is designed for open web media, podcasts, royalty-free audio archives, lectures, and educational platforms.
Never. All Digital Signal Processing (DSP) and WAV encoding occur 100% locally within your browser's local memory. Your audio never touches an external server.
No. Audio Sampler respects user privacy completely—we collect zero browsing history, zero analytics, zero personal data, and zero diagnostic telemetry.
No account or registration is required. You can install the extension and begin capturing audio instantly without signing up or logging in.
