I think I will let the image introduce program this time. This is gramofile:
The home page says 2001 but the package says 1998, but whichever you prefer, gramofile has been around for a long time in one form or another.
And as far as I can tell, with a few shortcomings, it seems to be working.
As you can see, some of the menu options aren’t functional, and playback seems to be tied to the old /dev/dsp arrangement, but some of the processing functions are still going.
Of course, I can’t really tell much difference in audio filtering quality. My ears are not that fine-tuned.
But I really like this. This is the style and arrangement I’d love to see in an audio tagging utility for the console. If one were ever to exist, of course. 🙄
