I find either Spoken Word or Vocal Booster do much the same thing.
I had my partner check with some Japanese song this morning and he thinks without eqMac it’s just slightly muffled in the voice, but nicer with eqMac.
As mentioned, I’m having an issue with eqMac and Facetime, but the developer is looking at it on Discord.
Somebody mentioned this might be due to loss of high frequency sensitivity with aging. Not impossible. I am 65 now. And I can’t really hear high pitch alerts on my Watch, so I set it to haptic. Still… the songs and voices on videos all sound find on my iPad Pro. So I tend to think it’s the speaker’s fault.
What I’m really curious is whether my MBP is an outlier, or if that’s just the way they are. I’m going to try (if my dog lets me) to go over to an electronics store today and see if I can hear a store model.
