I use an mp3 player for practicing ballroom dancing. Dancers learning a new routine find it very useful to be able to slow the music down by a variable factor of up to about -20% in fairly fine increments (of say 1% or 2%). Variable play-speed control is quite common on software music-players and on pro sound equipment used in dance studios, but not as common on portable music players. Still, there are some portable players that can do this (e.g. Creative's MuVo Vidz, and Astone's Samba and MicroAv).
Some do it better than others. On some, the pitch changes with the speed, producing a "Mickey Mouse" effect at higher speeds and a "Darth Vader" effect at lower speeds. Others use DSP to compensate for the change in pitch (usually with a process called Formant Correction), enabling the tempo to be varied without affecting the pitch.
Is there any chance of getting the ipod Nano to do this? Why particularly the Nano? Because for dancing, jogging and similar sports it is better to use a player with flash memory rather than a micro hard-drive, which is susceptible to shock.
Note: some ipods can already do this, but only for audiobooks, not for music. Shouldn't be too hard to get this feature to also work for mp3 music?
