Cassette Simulation This project simulates cassette tape audio profiles using ffmpeg. It applies tape noise, wow and flutter pitch modulation, bandwidth limits, and equalizer adjustments. Prerequisites bash ffmpeg (compiled with libmp3lame) Repository Structure BASF LH Extra C90: German ferric tape. Moderate hiss and mild flutter. Maxell UD C90: Higher-grade ferric tape. Lower hiss, wider frequency range. Sony CHF60 Type I Normal (1978): Vintage 60-minute normal tape. Warm mid-range. Sony CHF90 (1978): Vintage 90-minute normal tape. Slightly higher tape speed drift. TDK D90 (1995-1997): Late-era Type I tape. Clean sound, subtle analog character. mk60: Soviet MK-60 tape. High tape hiss, heavy wow and flutter, aggressive frequency cut.
