I don't really understand where you'd use it. > There is no "2% thing." The original poster said that Exactly *this* is the reason why I asked the OP to not tell wrong facts like they were true. It causes confusion about *the users*. When you read the manual you'll find out there are two ways to affect the pitch: you can change the pitch by using the up / down button. This will change the pitch in 0.1% steps (with increasing steps as you hold the button longer). These values are sticky, i.e. they remain after you let go of the button. The second way is to use the left / right buttons. Those will change the pitch by exactly 2% of the current setting, that value will be never anything else than 2% and it is *not* sticky. I.e. after letting go the button the pitch value will go back to the value you had before pressing the left / right button. This is intended for beat matching and intended to work exactly this way. A short scenario: you are playing music with say two h100 devices. Both are hooked up to a mixer, and you fade from player A to the other B. Now A plays a song. You want to smoothly fade into B. You changed the pitch so the beats of both songs have the same speed. Now, say B is 1/2 tick off of the beats of A. This is where beat matching is needed. You nudge the playback of B by increasing the playback speed only a little and change back to the original pitch as soon as the beats match. For this you need some pitch modify function that is not sticky, and that is the "2% thingy". It's giving the music a small nudge to match the beats. Nudging is in no way different to the pitch change Rockbox does. It is only a non-sticky mode with a fixed value. I hope this is now cleared completely. Changing the speed without affecting the music tone (aka timestretching) or changing the music's tone without affecting the playback speed (aka pitch shifting) has been requested several times but it is currently not possible. Btw, the buttons I refered in this mail are the ones for h100 series. For other players please look them up in the manual. - Dominik Received on 2007-01-07 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
