VP file extension - VOCPACK lossless compressed audio file
What is vp file? How to open vp files?
File type specification:
The VP file extension is also used by VOCPACK, a compressor or decompressor for 8-bit digital sound using a lossless algorithm; it is useful to save disk space without degrading sound quality. It can compress signed and unsigned data, sampled at any rate, mono or stereo. Since the method used is not lossy, it isn't necessary to strip file headers before compressing.
VOCPACK was developed for use with .VOC (SoundBlaster) and .WAV (Windows) files, but any 8-bit sound can be compressed since the program takes no assumptions about the file structure.
The typical compression ratio obtained goes from 0,8 for files sampled at 11 KHz to 0,4 for 44 Khz files. The best results are obtained with 44 KHz sounds (mono or stereo): general-purpose archivers create files that can be twice longer than the output of VOCPACK. You can obtain smaller values using lossy compressors but if your goal is to keep the sound quality unaltered you should use a lossless program like VOCPACK.
