Old Recording Cleanup

You have old recordings on cassette tapes, VHS, answering machine tapes, or early digital files that are noisy, degraded, or hard to understand — and you want to restore and preserve them.

Old recordings carry sentimental and historical value that makes their quality issues worth addressing. Modern AI tools have made restoration of analog-era recordings dramatically more effective than even five years ago. **Types of old recordings and their specific problems:** **Cassette tape transfers:** Tape hiss is the defining problem — a broadband high-frequency noise from the tape's magnetic coating. Additionally, older tapes develop 'shed syndrome' (oxide particles shedding, causing dropouts) and 'sticky shed syndrome' (binding, causing squealing) that create audio artifacts. AI noise removal handles tape hiss very effectively. Dropouts require spectral repair (iZotope RX Spectral Repair or Audacity's Click Removal). **VHS camcorder audio:** VHS recordings used linear audio tracks of variable quality. Tracking problems cause periodic dropout artifacts. The audio bandwidth was limited (max ~10kHz for Hi-Fi VHS, lower for standard linear track). After digitizing from VHS to MP4 via capture card, apply noise removal and high-shelf EQ boost at 4-6kHz to compensate for the VHS audio bandwidth rolloff. **Answering machine and voicemail archives:** These are often at telephone quality (8kHz, 4kHz max frequency). The memories are priceless; the audio fidelity is minimal. AI cleanup removes background noise and improves speech intelligibility within the bandwidth constraints. **Early MP3 and digital recordings:** Files from early 2000s digital recorders were often recorded at 8-16kHz sample rates with low-bitrate compression. MP3 artifacts appear as smearing above 10kHz. Cleanup focuses on noise removal rather than quality recovery above the Nyquist limit. **Digitization workflow (if not yet digital):** 1. Cassette or VHS → audio interface → Audacity → export as WAV (44.1kHz, 16-bit minimum) 2. Or use a cassette-to-USB converter device 3. Then apply noise removal and cleanup processing **Post-digitization cleanup:** 1. Noise removal: AI (Voice Isolate) for complex noise, Audacity Noise Reduction for pure tape hiss 2. Clicks and pops: Audacity Click Removal or iZotope RX De-click 3. Normalize to -12 to -6dBFS (preserve headroom for family sharing/editing) 4. Export as FLAC (lossless) for archiving; MP3 at 192kbps for sharing
