免费在线 MPEG-2 转 AMR 转换器

MPEG-2 is a video coding format, first standardized in 1995 and revised in 2013. Due to relatively low computational complexity this standard gained popularity and massive native implementations in video hardware. Hence MPEG-2 has actually become a standard in satellite and cable broadcasting. MPEG-2 is also used for creating DVDs for the same reasons (native hardware support by DVD players).

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.
