Many analog processes and techniques have been used in the past with varying degrees of success. Although digital noise-removal systems can be more effective, they are usually expensive, complex, and require considerable training to operate. Consequently, many films that could benefit from a thorough audio cleaning are not restored due to financial considerations. This paper describes a dynamically controllable broadband noise filter, based on digital signal processing (DSP) techniques, which is both simple to use and comparatively inexpensive.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptej/10.5594_J04667.xml)", "source": "parsed", "updated": "2026-05-22T18:56:53.245Z", "version": "smpte-journal-article-nlm@v1" }, "authors": [ { "affiliation": "Walt Disney Pictures and Television.
