If you like to have an analog-style pitch control for your music, like the pitch control on a turntable, DJCJ Player is for you. You can set the low and high value of the pitch control slider from -50% to +50%. It allows pitch shift in as little as .01% increments. Pitch and speed increase together just like on an analog turntable. Optimum sound quality is maintained. Free. No Ads. No subscriptions. No in-app purchases. Just a gift from DJCJ to you. This app will only play music that is synced to your device. It does not play music from any subscription streaming service. It does not play DRMed music.
