Boilsoft WV to M4R Converter tutorial

Glossary

WavPack (WV) allows users to compress (and restore) all PCM audio formats including 8, 16, and 24-bit ints; 32-bit floats; mono, stereo, and multichannel; sampling rates from 6 to 192 kHz. Like other lossless compression schemes the data reduction varies with the source, but it is generally between 25 % and 50 % for typical popular music and somewhat better than that for classical music and other sources with greater dynamic range.

M4R, widely used as a ringtone format, refers to MPEG-4 Part 14 or MP4 file format, formally ISO/IEC 14496-14:2003,which is a multimedia container format standard specified as a part of MPEG-4. It is most commonly used to store digital video and digital audio streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still images. Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. A separate hint track is used to include streaming information in the file. The official filename extension for MPEG-4 Part 14 files is .mp4, thus the container format is often referred to simply as MP4.
