無料オンラインVOBからAMRへのコンバーター

VOB is a format for DVD files that are usually stored in the VIDEO_TS folder. VOB is based on MPEG-2 and it can contain video, audio, subtitles and other data. Each file should be less than 1 GB to be compatible with all operating systems, otherwise they will not be read.

This format was originally intended for voice compression and is able to change the bit rates of encoded audio data. AMR is actively used for encoding and decoding voice while its being transmitted over network channels. The format allows one to consider network capacity and adapt it to channel loads. Due to this, the voice quality is practically undiminished.
