(6) muxmkv.cmd - batch encoder/muxer for mass/queued/parallel video encoding. Uses x264.exe for AVC/H.264 video and various audio encoders (Nero AAC, CT AAC, Fraunhofer AAC, Vorbis aoTuV, MP3, FLAC, WavPack, TTA). Supports job queue, multiple parallel encodings from common queue, lossless caching, partial encodes with automated shift for --zones "..." and many other features.
(7) audcvt.cmd - batch audio converter/tagger. Supports various lossless and lossy formats. It has limitations with tags transfers in some cases, because of lack of universal CLI taggers. So in general Foobar, Xrecode or dbPowerAmp may be better as simple converters. But there are some more complex things where GUI becomes inappropriate...
