- Analog tape recording, dominant since 1947, is widely used but threatened by mildew due to adhesives, affecting long-term preservation and sound quality.
- The study used ATR-FTIR, SEM, and laser microscopy to characterize tape properties and analyze Penicillium and Aspergillus mildew effects on audio via Praat.
- Research reveals the mechanisms linking mildew coverage to spectral characteristics and acoustic parameters, informing improved preservation strategies.
- Funding was provided by multiple Chinese foundations, including the National Natural Science Foundation of China and the National Archives Administration.
