How does in-browser AI noise reduction work?

Drop & Clean executes compiled WebAssembly (WASM) neural networks locally on your CPU/GPU threads inside the browser sandbox. Media files stay on your device during processing; anonymous diagnostics may be sent if enabled.

Will my 4K/HDR video lose quality during export?

No. Drop & Clean features bit-exact video passthrough using WebCodecs and the built-in Media Service. Only the audio track is extracted and cleaned; the video stream (including 4K/8K resolution, 60fps frame rate, and HDR color metadata) remains unchanged without lossy re-encoding.

Are my files private and secure?

Media files are processed locally in your browser and are not uploaded. Anonymous diagnostics may be sent according to your privacy settings; see the Privacy Policy for details. Local processing alone does not guarantee compliance with every GDPR or CCPA obligation.

Pristine 4K Vlog Audio Guide

How modern video creators reduce camera preamp hiss and room reverberation while preserving the original 4K 60fps HDR video stream.

1. Executive Summary & Production Challenge

Content creators filming on smartphones, Sony FX3, or mirrorless rigs constantly battle background room resonance, refrigerator drone, and built-in mic self-noise. Traditional video editors require lossy audio-video re-rendering that degrades visual bitrates and takes minutes to export. Drop & Clean solves this dilemma by decoupling audio processing in-browser with zero-transcode video passthrough.

2. Acoustic Physics & Spectrogram Breakdown

Vlog background noise typically occupies the 80Hz to 400Hz range (room standing waves, HVAC hum) combined with wideband white noise from budget shotgun mic preamps. When creators speak, these noise artifacts cause masking effects across the 2.5kHz voice clarity region. Our 32-band ERB filterbank isolates vocal harmonics from stationary background energy with surgical precision.

3. In-Browser Neural Network Processing

The EXPRESS 48kHz engine processes audio locally. Preview time depends on your device and recording. WebCodecs replaces only the audio track while preserving the original video stream.

4. Step-by-Step Calibration & Workflow

1. Drop your raw camera MP4 or MOV into the Studio. 2. Select Express ⚡ mode for general ambient noise or Pro 🚀 mode for heavy room echo. 3. Adjust the Dry/Wet slider between 75% and 90% to maintain natural acoustic room air. 4. Click Save Clean File to export the processed video; time depends on your device and recording.

5. Measured Audio Metrics & Benchmark Results

• SNR Improvement: +21.4 dB • Visual Quality Delta: 0.00% (Bit-exact H.264/HEVC/ProRes passthrough) • Preview time varies by device and recording.
