How to Extract M4A Audio from AVI Video
Pull the audio track from any AVI video and save it as a standalone M4A file
Select a AVI video file containing the audio you want to extract. Works with music videos, recorded lectures, podcast recordings, or any video with an audio track. There is no need to install editing software — the entire extraction happens in the cloud.
The audio track is separated from the video frames and encoded as M4A. Video data is discarded cleanly — the resulting file contains only the audio at the selected quality level.
Download your extracted M4A audio file — typically 90% smaller than the original video. Ready for music players, podcast apps, or further editing in any audio workstation. Files are deleted from our servers automatically after processing.
Why Convert AVI to M4A
M4A is the standard audio format for iPhone, iPad, Mac, and Apple Watch. Voice memos, Apple Music downloads, and iTunes purchases all use M4A for the best playback experience on Apple hardware.
M4A uses AAC encoding, which delivers superior audio quality compared to MP3 at equivalent bitrates. At 256 kbps, M4A is virtually indistinguishable from CD quality to most listeners.
M4A containers can hold Apple Lossless (ALAC) encoded audio for bit-perfect quality. Apple Music Lossless subscribers receive ALAC in M4A files for the highest quality listening experience.
M4A supports chapter markers with titles and artwork, making it ideal for enhanced podcasts. Listeners can jump between segments and see chapter-specific images in compatible podcast apps.
M4A (and its M4B audiobook variant) efficiently compresses long spoken-word content with chapter navigation and bookmark support. Apple Books and other audiobook apps handle M4A files natively.

About the AVI Format
AVI (Audio Video Interleave) is a multimedia container format introduced by Microsoft in 1992 as part of its Video for Windows technology. It is one of the oldest video container formats still encountered today. AVI uses a straightforward structure where audio and video data are interleaved — stored in alternating chunks — allowing simultaneous playback of both streams. Its simplicity made it a dominant format throughout the 1990s and early 2000s.
While AVI benefits from broad legacy support and a simple, well-understood structure, it lacks many features expected in modern video formats. It has no native support for streaming over the internet, cannot embed modern subtitle formats or chapter markers, and its compression efficiency depends entirely on the codec used. AVI files also tend to be larger than equivalent MP4 or MKV files. The format is being gradually replaced by MP4 and MKV in virtually all use cases, though it still appears in older video archives and some legacy industrial systems.
