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 | ? (built-in) |
| AAC | FAAD |
