He wants to pitch up the music as a production and presentation effect.
It is very common in pop formats to do so. It used to be done when the
music was placed on a tape cartridge or during playback by intentionally
speeding up th studio turntables. Now, most stations do it on the fly in
the automation system playback by setting it in the category settings.
The common "pitch up" is between 1.5% to 3% After that, the effect is
very noticeable. Those with perfect pitch ears can detect they key
chance even at 2%.
Our MediaTouch system does it and I hadn't looked at whether Rivendell
could do it, since we have awhile before we transition to opensource.

Shifting pitch isn't the only way to compress the time. If you use an
AudioScience card, Rivendell can increase or decrease the playback
speed on the fly without changing the pitch or affecting the imported
files because AudioScience licensed the time shifting technology for
their sound cards from 25/7 systems.

Other than as a means to make the songs use 2% less air time, I can't
think of any other reason to pitch shift the music by 2%. Can you
share more about what you're hoping to accomplish, and for what
purpose? With a little bit more information about what you want to
do, the community might be able to suggest other viable solutions to
achieve the desired result besides the one you already have in mind.

I want to pitch shift all music, leave
station IDs and adverts alone. Can it
be done in Rivendell without
permanently changing the imported file?
