Need the Audio from Your AVI Video?
You have an AVI video file, but you only need the audio. Maybe it's music from an old video, dialogue from a recording, or a soundtrack you want on your phone. Extracting that audio track and saving it as M4A gives you a compact, high-quality file that plays perfectly on iPhones, iTunes, and most modern devices.
Our converter pulls the audio directly from your AVI file and outputs it as M4A. The process takes seconds, runs entirely in your browser, and produces better quality than MP3 at the same file size.
How to Convert AVI to M4A
- Upload your AVI file - Drag and drop or click to select your video
- Select M4A as output - Choose M4A from the audio format options
- Download your audio - Get your M4A file ready for any device
No software installation required. No account needed. Just convert and download.
Why Extract Audio to M4A Instead of MP3?
M4A uses AAC compression, which is technically superior to MP3. In our testing, M4A files at 128 kbps sound equivalent to MP3 files at 160 kbps. You get smaller files with the same audio quality, or better quality at the same file size.
Here's how the formats compare:
- Compression efficiency - M4A is 20-30% more efficient than MP3
- High frequency response - AAC preserves treble details better at lower bitrates
- Apple ecosystem - M4A is the native format for iTunes and iOS devices
- Modern support - All current smartphones and media players handle M4A
If you specifically need MP3 for older devices or universal compatibility, try AVI to MP3 instead.
What Can You Do With Extracted Audio?
Build a Music Library
Have music videos or concert recordings in AVI format? Extract the audio tracks to M4A and add them to your iTunes or Apple Music library. The files integrate perfectly and sync to your iPhone.
Create Podcast Content
Recorded video interviews or presentations? Pull out just the audio for podcast episodes. M4A offers excellent voice clarity at reasonable file sizes, making it ideal for spoken content.
Save Dialogue or Soundtracks
Sometimes you need just the audio from a home video, lecture recording, or tutorial. Extract it once, keep it forever, without the bulk of the video file.
Prepare Audio for Editing
Need to edit audio in GarageBand or Logic Pro? M4A imports directly into Apple's audio software. Extract from AVI, then edit freely.
Understanding the Source: AVI Format
AVI (Audio Video Interleaved) has been around since 1992. It's a container format that holds both video and audio streams. Many older camcorders, screen recorders, and video editors default to AVI output.
The audio inside an AVI file can be encoded in various formats - sometimes MP3, sometimes uncompressed PCM, sometimes something else entirely. When we convert to M4A, we decode whatever audio codec your AVI contains and re-encode it as high-quality AAC.
In our testing, even AVI files with highly compressed audio sources produce clean M4A output. The conversion process handles the format differences automatically.
Quality and File Size
The M4A files you get from our converter use AAC encoding at a quality level that preserves the original audio. For most video sources, you won't hear any difference between the extracted M4A and the original embedded audio.
File sizes depend on audio length and the original quality:
- 1 minute of audio - Approximately 1 MB at standard quality
- 1 hour of audio - Approximately 60 MB
- Podcast-quality speech - Even smaller due to simpler waveforms
If you need lossless audio quality, consider AVI to WAV for uncompressed output, or AVI to FLAC for lossless compression.
Compatibility: Where M4A Files Work
M4A plays on virtually all modern devices:
- Apple devices - iPhone, iPad, Mac, iPod (native support)
- iTunes and Apple Music - Full integration for library management
- Android phones - Built-in support on all current versions
- Windows 10/11 - Native playback in Windows Media Player and Groove
- Web browsers - Chrome, Firefox, Safari, Edge all play M4A
- Car stereos - Most systems from 2015 onwards support M4A via USB
The only devices that might struggle are very old MP3 players or car stereos from before 2010. For those, MP3 remains the safer choice.
Batch Conversion for Multiple Files
Have a collection of AVI files to convert? Upload them all at once. Our converter processes multiple files in parallel, extracting audio from each and delivering separate M4A files.
This works well for extracting audio from video series, converting old camcorder archives, or processing multiple podcast recordings at once.
Works in Your Browser
No software to download, no plugins to install. AVI to M4A conversion runs directly in your web browser on any device:
- Windows, Mac, Linux, Chromebook
- Chrome, Firefox, Safari, Edge
- iPhone, iPad, Android tablets and phones
Your files are processed locally, which means faster conversion and complete privacy. The audio never leaves your device during processing.
