Convert AAC to AVI — Free Online Converter

AAC is a pure audio codec, while AVI (Audio Video Interleave) is Microsoft's classic multimedia container introduced in 1992. Converting AAC to AVI creates a video file with a static or blank video track and the audio content as the soundtrack. This unusual conversion is used when software or hardware strictly requires AVI input — such as legacy video editing programs or industrial media players that cannot import standalone audio files.

Some legacy video editing software, industrial display systems, and embedded media players only accept AVI files. If you need to include audio in a timeline or playout system that rejects standalone audio formats, wrapping the AAC stream in an AVI container with a blank video track is the practical workaround. This also enables using audio files in video production pipelines that expect a video container.
