I'm in the process of transferring my cassettes to CD...one thing I've noticed is my cassette deck's playback speed is about 3% faster than it should be. I noticed this difference after transferring songs on tape and comparing the same songs on CD. (These are standard size audiocassettes.) Normally I wouldn't mind but because these are karaoke tapes and will be used by myself and others, it will make a difference. Is there any way to adjust playback speed on my tape deck? Are there any tape decks that will play standard cassettes and allow me to adjust playback speed?
Pitch control was a somewhat infrequent feature on most cassette decks. Many of the Nakamichi, Teac, Tascam and upper end Sony decks had pitch control. I can't say for certain you can find the feature today but it would most likely be on an upper end deck or a cassette machine geared to the professional market. Sony made some Pro Walkman and Tascam has made a studio deck with pitch control. This of course requires buying a new deck. I know of no way to add pitch control to an existing deck.
