AudioCatalyst is a CD ripper and audio encoder based on the ever-popular AudioGrabber and XingMP3 Encoder. Features include CDDB support, the option to save as either a WAV or an MP3 file with or without the intermediary WAV file, definable encoding start and stop times for partial encoding of audio tracks, normalization for automatic correction of recording volume, support for multiple data rates, a checksum utility for file verification, sampling up to 20 kHz, and variable bit rate encoding. This download now includes the XingMP3 Player. The trial version of AudioCatalyst has three main limitations: WAV files from the hard drive cannot be encoded to MP3, only randomly selected tracks can be encoded, and tracks can only be encoded at 128 kbps.
