why do audio tapes play at different speeds in different cassette decks?
the current car that i have only has a cassette deck. so i thought of doing music recording the old fashioned way, which is record a cd to a tape. but in my car the music sounds slower that is cd quality. the odd part is that the stuff that opens the tape (old radio recordings of adam sandler holiday songs) sound regularly. should i try recording them using a different player?

Wow. It's down to variations in the speed of tape player transports. It is less of a problem in digital systems.
Low-frequency flutter (below 1000 Hz) is caused by the rotating parts of a tape transport such as: Irregular magnetic tape supply or take-up reels. Uneven or sticking guide rollers and pinch rollers. Capstans. High-frequency flutter (above 1000 Hz) is caused by the fixed parts of a tape transport, such as fixed tape guides and magnetic heads. When the magnetic tape passes over a fixed tape guide or magnetic head, the transition from static to dynamic friction causes something called stiction. It's this stiction that causes the variations in tape speed which, in turn, cause the flutter. As you might guess, it's hard to prevent flutter. The only way to lessen flutter is through skilled engineering, machining, and design of magnetic tape recorders. |
Whats an audio "tape"?

Actually, CDs play at slightly different speeds in different players, too.
