Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding scheme for digital audio. AAC generally achieves better size than APE at similar bit rates. Now you can enjoy the versatile movies on your MP4 Player wherever and whenever. Simple settings, high speed, and friendly interface. It is very easy to use without any special setting, only a few clicks complete the task of backup CDs; Backup and Encoding in same time. It can detect your hardware configuration and decide an optimized convert scheme automatically; Provide greater than 300% converting speed by multithreading, so fast beyond your imagination; Both multithreading and batch conversion supported; Automatically shutdown the computer after conversion.
