Local Interview Denoising

Process sensitive depositions, investigative journalism recordings, and medical consultations locally in your browser. Media files are not uploaded; anonymous diagnostics may be sent if enabled.

1. Executive Summary & Production Challenge

Legal depositions, psychiatric evaluations, investigative journalism recordings, and corporate M&A discussions contain strictly confidential intellectual property and protected health information (PHI/HIPAA). Uploading unredacted client recordings to third-party cloud transcription or audio cleaning SaaS platforms violates legal privilege and strict confidentiality agreements.

2. Acoustic Physics & Spectrogram Breakdown

Surreptitious and handheld interview recordings suffer from low signal-to-noise ratio (SNR), far-field microphone positioning, HVAC drone, and acoustic reverberation in sterile conference rooms. Weak spoken consonants are easily masked by low-frequency floor rumble and ambient air conditioning.

3. In-Browser Neural Network Processing

Drop & Clean processes audio and video locally in your browser using WebAssembly and WebCodecs; media files are not uploaded. Anonymous diagnostic data may be sent according to your privacy settings and does not include media contents.

4. Step-by-Step Calibration & Workflow

1. Open Drop & Clean in a modern browser. 2. Drag and drop your WAV, MP3, or MP4 recording. 3. Select Express Mode for conversational clarity or Pro Mode for heavy ambient masking. 4. Export the processed audio or video; processing time depends on your device and recording.

5. Measured Audio Metrics & Benchmark Results

• Media files are processed locally; diagnostic data is separate. • Automated Speech Recognition (ASR) WER: -44.2% reduction • Processing time depends on your device and recording length.

Frequently Asked Questions

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.
