DoubleTrack app for iPhone and iPad

DoubleTrack is easy to use. Simply load your a voice podcast and a music podcast. Adjust the volume of the music podcast and the speed of the voice podcast and enjoy your favorite music and educational content simultaneously.

DoubleTrack helps make educational programs more enjoyable by allowing listeners to speed up the voice podcasts and audio books (up to twice as fast) while simultaneously listening to their favorite music podcasts at a reduced volume.

By speeding up educational material, you can get through the content in half the time. By playing enjoyable jazz, classical, electronic or other instrumental music in the background, the learning process is also more enjoyable.
