Software to easily maintain collections of mp3 files with the best quality and the smallest size, taking into account both the maximum required quality and the compatibility with the target player.
Uses the latest version of LAME, version 3.100, customly compiled to adapt to the in-use cpu, so that it can be used with cpus as old as the Pentium and Windows versions as old as Windows XP.
The program is profile based, to make it easier to use. Specifically, there are two main profiles, the Audiophile (bitrate 320kbps) and the on-the-go (bitrate 192kbps) ones, which are further subdivided in stereo or mono.
The encoding method for mp3 files can be chosen (abr, cbr, or vbr), so that one can choose whether to use the better encoding method in terms of both quality and file size (variable-bit-rate = vbr) or the most compatible one (constant-bit-rate = cbr).
As encoding audio into the mp3 format is a lossy operation, whenever possible the original audio is not re-encoded, being the stream corresponding to it just copied to the target file as is or with its frames re-formatted as required to be in accordance with the target format; when this happens, the process is lossless and, as so, does not use LAME but code specifically created for the purpose by the author of this program. The information regarding whether or not the audio on the original file has been (re-)encoded is shown on the information displayed by the program on its grid view.
The program is batch-based, meaning that as soon as the settings are chosen they can be applied to as many files as you wish - you just have to let it process all of them.
Last but not least, the program does not require any installation - it is a portable one. Thus, it can be run from a pen drive.
