CoPO Evidence Lab

CoPO Evidence Lab gives plaintiff trial attorneys a private, on-device workstation for audio and video evidence — without sending a single file to the cloud. Every file stays on your iPhone or iPad. No accounts. No AI. No cloud. Your evidence, on your terms. ORGANIZE BY CASE Create cases by name and docket number. Import audio and video from the Files app. Every file is fingerprinted with a SHA-256 hash at import, and every action you take is logged with a timestamp. AUDIO ENHANCEMENTS Clear Speech — Band-limits to the speech range (80 Hz–8 kHz), applies FFT spectral noise reduction, and normalizes loudness to the EBU R128 broadcast standard. Bodycam audio gets significantly more intelligible. Level Volume — EBU R128 normalization only. Raises quiet passages and limits peaks without altering frequency content. Remove Hum — Notch filters for 60 Hz US mains hum (plus harmonics) or 50 Hz for international footage. Isolate a Channel — Extract the left or right channel when a two-mic setup recorded each source separately. Slow to 75% — Time-stretch to three-quarters speed while pitch is preserved. Easier transcription, no distortion. VIDEO ENHANCEMENTS Stabilize — Measures camera shake frame by frame, then crops slightly and shifts each frame to hold the picture steady. If the footage can't be measured reliably, the app declines rather than produce a misleading copy. Brighten Low-Light — A luma-only gamma lift that raises shadow detail without shifting colors. Sharpen Soft Footage — A luma-only unsharp mask for slightly-out-of-focus or compressed footage. Correct White Balance — Gray-world white balance for footage with a color cast. Upscale 2x (Lanczos) — Higher-resolution interpolation for easier viewing. BODYCAM PACKAGE Run Stabilize + Brighten + Clear Speech in one documented pass — the most common enhancement workflow for bodycam footage, delivered in a single tap and fully logged. CHAIN OF CUSTODY BUILT IN Every import, enhancement, and derivative file is logged with a precise timestamp and the SHA-256 hash of both the source and the output. Verify any file's hash at any time inside the app. Export the full processing log as a JSON document for your case file. COMPARE AND DOCUMENT Play the original and the enhanced copy side by side. Export a draft declaration (PDF) describing exactly how an enhanced copy was made — every command, software version, and SHA-256 hash — ready for your review before signing. FREE AND PRO Free: enhancements process the first 60 seconds of each file. Evidence Lab Pro unlocks full-length processing and declaration export. Pro is an auto-renewing subscription, billed monthly or yearly. Payment is charged to your Apple Account at confirmation of purchase.
