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.
How to Use
Navigate to any cassette folder and run the scripts:
# Convert local audio files (mp3, ogg, m4a, aac)
./convert_cassette_*.sh
# Record a live web stream into segment files
./record_stream_cassette_*.sh [STREAM_URL]
Processed output files will be saved in the ./out folder.
