====== Audio decoders ====== The following table shows which input audio formats Avidemux supports. If the information in the "Decoder" section says "built-in", it means a decoder for the format is included in the Avidemux source code and you have nothing to install. If the decoder is not built-in, Avidemux can optionally use an external decoder for the format, if it was compiled with support for it. ^Format ^Decoder ^ |MP3, MP2 |libmad | |A52 aka AC3 |liba52 (built-in) | |DTS aka DCA |libdca | |Vorbis |libvorbis | |AMR Narrow Band |?
