MP3 Joiner Splitter is a FREE mp3 splitter and joiner. Cutting up of strings can be by length, size and count. The length count is valid up to 24 hours starting from 1 sec. The size, meaning the file size, can be anything up to 4 GB and count can be up to 10,000. You have to specify the output folder in case of joining or splitting. The encoder settings need to be done in terms of the sampling frequency, bit rate and the number of bits to be used per sample. You could do the operations in a batch. The ability of developers managing joining and splitting of compressed encoded file is remarkable, to the end user this is a very small functionality unless you have a really large volume workload. The rightful place for such a feature would be a ripping/converting software.
The interface is very easy to use, integrates Windows explorer like features. Batch listing area can be used along with that or files could be dragged and dropped into the work area. The splitting/joining operations are done on-the-fly, no temporary files are generated. The tool works with Windows up to Windows 7, both 32 and 64 bit versions. The program takes advantage of the multiprocessor/multi-core systems and thus as the processor on your machine gets upgraded, your program should run so much faster!
