PLAYBACK AT 432HZ

Recently I was reading up on musical pitches and learned that music is tuned to a 440Hz pitch, which has a negative effect on the listener.

Relatively recently audio players have been created to pitch down music to 432Hz for not only better listening, but to remove the negative aspect of up pitching music to 440Hz.

Is it possible to incorporate the playback function of Rockbox to 432Hz so that all music plays at this pitch?

I have researched the issue and found that in order to correct this problem that effects all music, it would require re-recording all music to the 432Hz pitch, which would be a nightmare for anyone with a sizable music collection, but it is easy for a audio player to correct that problem on the fly.

Just wondering if that can be done with your product

Thanks

My personal advice is to stop reading bullshit about earth own frequency and such supporting 432 Hz pitch. Historically there were different tunes used for instruments and usually the reason for change was either technical (downtune for some choral music for example) or purely subjective.

Anyway you can change pitch with or without affecting time in rockbox:

It's not possible for Rockbox to pitch all your music to 432 Hz in an easy way, because you have to analyze your music first:

* concert pitch in the baroque period was usually much lower than today; baroque orchestras which play historic instruments (respectively replicas) play at a 415
Hz pitch.
* in the following epoche concert pitch rose; "historic" orchestras playing classical (Viennese Classic) usually play at 430 Hz pitch.
* historic romantic music is often played at 435 or 438 Hz. 440Hz or 430Hz is possible, but less common.
* most modern orchestras play at a higher pitch, somewhere between 442 and 445 Hz.
* Recordings containing (historic) organs can be literally anywhere in pitch. Recordings of the same organ can be different because the pitch changes because of temperature or other climatic reasons. The same applies for any other instrument that can't be easily tuned.
* many recent rock bands play at 415 Hz pitch (downtuned one semitone)
* it was a common practice in the time of analog tape recorders to speed up/slow down any kind of popular music, which of course affects the pitch in one or the other direction

Do you intend to listen to everything at 432 Hz, i.e. pitching a music piece in the key of g (correspond to 392 Hz) up to 432 Hz?

I am only keeping what may be usable in your comment.... but thank you for it  ::)

May I ask why you want to listen to "detuned" music? Except for playing along with a detuned instrument?
