Simulate Authentic Cassette Tape Audio Profiles Using FFmpeg
Simulate cassette tape audio profiles using FFmpeg
I built a project to simulate cassette tape audio profiles using FFmpeg, applying tape noise, wow and flutter, and bandwidth limits. The repository includes scripts for various tapes like BASF, Maxell, Sony, TDK, and the Soviet MK-60, each offering distinct analog characteristics from warm mid-ranges to heavy hiss.
Soviet MK-60 tape features high tape hiss, heavy wow and flutter, and an aggressive frequency cut.

How would one go about determining what effect to add for each cassette type? I don't know much about cassettes, I'm curious if this was something that could be done by ear or if these are commonly held opinions about the sound of each tape.
Again knowing nothing about tape, if I were tasked with this I would probably try to record the same audio to each of the tapes and then compare it with the original.

Has anyone come across a Dolby B (or similar) encode / decode program?
I've been wanting to experiment with quantizing Dolby (or similar) encoded audio to 8 bits, and then unencoding to see how well it can sound.

This is awesome and very useful for one of my projects !! Thank you so much

This is interesting as I would assume multiple passes from each output would result in further multi generational loss akin to tape trading of band demos, soundclashes and dj mixes from pirate radio

I’m wondering besides the hiss and wow/flutter, what is the frequency range of cassette tape? Is there an “eq” to tape where certain frequencies are rendered more strongly than others? And how does it compare with records?
