AB MP3 Encoder is a fast application which will encode your WAV files into MP3 files. You can make a waiting list up to 100 different WAV files. Two progress bars will tell you how much has been done and how much has remained. Also, two independent clocks will estimate the time which has remained. You can include checksum data (CRC), set the private-bit, set the copyright-bit, clear the original-bit in the output file and automatically delete source file after succesfully encoding. Allowed bitrates are: 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256 and 320. Priority levels are: highest, higher, high, normal, lower, lowest, idle. It's small (exe file has just 28 Kb) and it has a really nice, friendly GUI.
