How It Works

Visual MP3 Splitter & Joiner can split and combine MP3 and WAV files. The program does its work miraculously fast. You add files to split or to join, hit F5 - and the output is there. It takes only a few seconds to produce a large (tens of megabytes) file.

How is that possible? Does the program do any harm to your files by performing so fast? Slower is surer, isn't it?

Not in this case. While other similar tools decompress MP3 to WAV, split (or join) the stream, and then recompress it again, Visual MP3 Splitter & Joiner chooses a different approach. It works directly with MP3 frames. No recompression takes place.

'Why recompression is bad?' sometimes we hear from users.

Well, first of all, it is slow. Uncompressed WAV stream is often ten or more times the size of original MP3. How much time will it take just to copy that kind of file on your hard disk? Several minutes are not uncommon even with short records.

Several minutes just for saving the copy that you don't need?

Exactly. The copy will be deleted after recompressing, and the hard disk space will be recovered, but not your time.

Another point with conventional splitters and joiners is recompression itself. It eats processor time for breakfast, slowing down your computer. More important yet, it can lead to quality losses.

Let's now take a look at Visual MP3 Splitter & Joiner.

If you want to cut an MP3 file into two parts (as an example), the program just copies the stream from the beginning to the point you've specified into the first output file, and from that point to the end - into the second one. It also copies some descriptive data needed to create a separate file, but in general it is the stream that matters. It remains unchanged - exactly as when you copy a file from one folder to another, or from CD to your hard disk. That's why Visual MP3 Splitter & Joiner takes so little time to get the work done. Basically it is the time that your system needs to copy a file of a comparable size.

Joining is much the same. The program copies two or more streams into one.

So, Visual MP3 Splitter & Joiner saves your time and preserves quality of your audio files.

One of the main reasons I bought Visual MP3 Splitter was the Silent detection tool. It worked very well and was a great time saver when splitting several mp3 files containing whole CD's.

I must also mention that the team at ManiacTools was very helpful when I got in to some trouble with a file that had a garbled header. I don't how they did it but now I split that file too...
