FFmpeg project simulates cassette tape audio profiles with noise, wow, and flutter
Key points
- Project uses FFmpeg to simulate cassette tape audio.
- Applies tape noise, wow/flutter, bandwidth limits, EQ.
- Includes profiles for specific cassette models.
- Processes local audio files or live web streams.
Cassette Audio Simulation with FFmpeg
A new project has been released that simulates the audio characteristics of various cassette tapes using FFmpeg. This tool applies specific audio effects to replicate the sound profiles associated with different cassette models and types.
Applied Audio Effects
The simulation incorporates several key audio effects to achieve the desired vintage sound. These include the addition of tape noise, pitch modulation through wow and flutter, the application of bandwidth limits, and specific equalizer adjustments tailored to each cassette profile.
Included Cassette Profiles
The project features profiles for several distinct cassette tapes. Examples include the BASF LH Extra C90 with moderate hiss and mild flutter, the Maxell UD C90 known for lower hiss and a wider frequency range, and vintage Sony CHF60 and CHF90 tapes. It also includes profiles for the TDK D90 (1995-1997) and the Soviet MK-60, which is characterized by high tape hiss and heavy wow and flutter.
Usage and Output
Users can process local audio files in formats such as MP3, OGG, M4A, and AAC, or record live web streams by providing a URL. The processed audio files are saved in an 'out' folder. The project requires bash and FFmpeg compiled with libmp3lame.
