Mp3 Audio Splitter Joiner is a digital audio editor supporting batch Mp3, WAV, WMA and OGG audio files. It allows you to split any of these formats and rejoin them - great if you're trying to reduce the size of a file or make your own music.
The good thing is that no quality is lost when you perform the cutting and splicing. You can join/merge multiple files into one big file with precision. All cutting is done with use of a simple timeline similar to what you might find in any video editing program. If you want to reduce the file size further, you can also choose the output rate and lower the frequency of the Mp3.
The program also includes a small player where you can set the start-time and end-time just to test your edits. You can also use this to cut the files using a slide bar along the timeline. Finally, it's also worth noting that Mp3 Audio Splitter Joiner can also convert between Mp3, WAV, WMA and OGG formats. This is a simple but powerful program only let down by the fact that the interface looks quite cheap and basic.
