We are pleased to offer the software packaged with four high quality music samples, courtesy of Bravura Records. The 24-bit music tracks are provided in both 96 kHz and 48 kHz formats in order to be compatible with older PC sound cards. We hope you try the software, and find that it improves you critical listening skills. This is a work in progress, and we expect to add more features and training tasks to this public version of the software over time. Enjoy!
