Restoring hundreds of hours of rare Buddhist teachings using neural audio processing

A seven-week project using neural speech enhancement and digital signal processing to restore 551 audio files comprising 371 hours of teachings by Kyabje Dilgo Khyentse Rinpoche — one of the most influential Tibetan Buddhist masters of the 20th century. Every file received manual quality assurance. The project handled severe technical challenges including 3-bit audio anomalies, corrupted files, sample rate mismatches, and unsupported legacy formats.
Neural speech enhancement to improve clarity and remove decades of noise, distortion, and reverb
Digital signal processing with cloud GPU infrastructure for batch processing
Manual QA on every single file — no automated-only outputs
Format standardization across 4 source collections with varying codecs and sample rates
Weekly progress reports submitted to Tsadra Foundation
Combined neural speech enhancement models with traditional DSP techniques. Cloud GPU infrastructure for batch processing. All restored files delivered to Tsadra Foundation's NAS system with a final report.
