Is it possible, as it is with Foobar2000, to tune Roon to playback at 432HZ instead of the standard 440?
I understand that if you tune instruments back and a singer sings a tad lower, you can be in 432.
But when a recording is made in 440 you would never go back to 432 and keep everything the artist intended. Guitars, voices, piana; yes. A snare-drum, also possible to tune. But the choice of a cymbal or hi-hat is fixed. Yes, you can choose another one in the recording but changing it afterwards doesn’t add up in my opinion.
Whim would you go back to something that wasn’t intended to be?
There is probably music that is played and recorded in 432, but most isn’t.
No can’t do.
Exactly this. Imagine musicians playing something at 440. Then suppose that they retune their instruments to 432 and play the same piece again. They would respond to the difference in sound and play it differently. Simply altering the pitch of a recording doesn’t represent how the musicians would actually play at the different pitch.
In an acoustic instrument, the frequency also interacts differently with the instrument’s body. (Edit: Even more so for for singers). It sounds different, and that’s not the same as recording at higher pitch and then lowering it with DSP. Lower pitches are often advocated by singers for purely practical reasons.
Anyway, orchestras are all over the place, like the Vienna and Berlin Philharmonic previously at 445, and it’s not even constant during a concert due to room climate.
If the idea behind tuning to 432 is to get an overall more mellow sound, the OP can lower the high mids and treble a bit with the equalizer in Roon
