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?
Of course it differed by brand.
It's also worth considering that a lot of tapes were recorded with Dolby B noise reduction, which boosted high frequencies on the recorded tape, to increase the signal to noise ratio. (You had to use Dolby B at the playback end, too, or it would sound too bright.)
