Need Audio from Your AVI Video?

You have an AVI video with audio you need-maybe dialogue, music, or sound effects. You want that audio in a format that works seamlessly with Mac applications and professional audio software.

AIFF is Apple's uncompressed audio format, delivering CD-quality sound without any compression artifacts. Converting your AVI files to AIFF extracts the audio track in a format that integrates perfectly with Logic Pro, GarageBand, Final Cut Pro, and other Mac-based editing tools.

In our testing, AVI to AIFF conversion preserves the original audio quality completely-no generational loss, no artifacts, just clean uncompressed audio ready for professional use.

How to Convert AVI to AIFF

  1. Upload your AVI file - Drag and drop or click to select your video
  2. Select AIFF output - Choose AIFF for uncompressed Mac-compatible audio
  3. Download your audio - Get your extracted AIFF file instantly

The entire process runs in your browser. No software installation, no account creation, no waiting for server processing.

Why Choose AIFF Over Other Formats?

AIFF (Audio Interchange File Format) was developed by Apple in 1988 and remains the preferred uncompressed format in the Mac ecosystem. Here's why it matters:

  • Uncompressed PCM audio - No quality loss whatsoever. What goes in comes out exactly the same
  • Native Mac support - Works immediately in QuickTime, Music app, iTunes, and all Apple software
  • DAW compatible - Logic Pro, GarageBand, Pro Tools, and Adobe Audition import AIFF directly
  • Metadata support - Stores title, artist, album, and other tag information
  • Industry standard - Trusted in professional studios for recording, mixing, and mastering

In our testing, AIFF files extracted from video sources maintained bit-perfect accuracy when compared to the original audio stream. This makes AIFF ideal when you need to edit, process, or remix the audio.

AVI vs AIFF: Understanding the Formats

AVI (Audio Video Interleave) is a video container format created by Microsoft in 1992. It can hold both video and audio streams using various codecs. The audio inside an AVI might be MP3, PCM, AC3, or other formats.

AIFF is purely an audio format-no video, just high-quality uncompressed sound. When you convert AVI to AIFF, you're extracting the audio track and encoding it as uncompressed PCM data.

Professional Use Cases

Music Production and Sampling

Producers extracting audio samples from video sources need uncompressed quality. AIFF delivers the full dynamic range and frequency response for chopping, stretching, and processing in your DAW.

Podcast Production

Converting video interviews to AIFF gives you clean source material for podcast editing. The uncompressed format means you can apply EQ, compression, and other effects without compounding quality loss.

Film and Video Post-Production

Audio editors working on Mac systems prefer AIFF for compatibility with Final Cut Pro and Logic Pro workflows. Extract dialogue or sound effects from AVI footage and integrate seamlessly into your timeline.

Voice-Over Extraction

Need the voice track from an AVI video for archiving or reuse? AIFF preserves every nuance of the original recording. When we tested extracting voice-overs, the AIFF output was indistinguishable from the original source.

Educational Content

Teachers and trainers often need to extract audio lectures from video recordings. AIFF ensures the audio remains clear and suitable for creating podcasts or audio-only versions of educational materials.

When to Choose Different Formats

AIFF isn't always the right choice. Consider alternatives based on your specific needs:

  • AVI to MP3 - When you need smaller files for portable devices or streaming. MP3 compresses audio by about 90% with acceptable quality loss for casual listening
  • AVI to WAV - If you're on Windows or need broad compatibility. WAV is the Windows equivalent of AIFF with identical quality
  • AVI to FLAC - When you want lossless quality with smaller file sizes. FLAC compresses without losing any data
  • AVI to M4A - For Apple devices when file size matters more than being uncompressed

Choose AIFF when: you're working on Mac, need uncompressed quality for editing, or your workflow specifically requires the AIFF format.

Technical Specifications

Understanding what happens during conversion helps you make informed decisions:

  • Sample rate - Our converter maintains the original sample rate (commonly 44.1kHz or 48kHz)
  • Bit depth - Audio is extracted at 16-bit or 24-bit depending on the source
  • Channels - Stereo and mono sources are preserved accurately
  • File size - Expect approximately 10 MB per minute of stereo audio at CD quality (44.1kHz/16-bit)

The converter automatically detects the audio parameters from your AVI file and creates an AIFF that matches the source quality. There's no downsampling or bit reduction unless the source audio is already lower quality.

Batch Conversion

Have multiple AVI files to convert? Upload them all at once. Our batch processing handles multiple files simultaneously, saving you time when working with large projects.

This is particularly useful for video archivists, podcast producers handling interview footage, or anyone processing a collection of video files.

Works on Any Device

Convert AVI to AIFF directly in your browser:

  • Mac, Windows, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • iPhone, iPad, Android tablets

All processing happens locally in your browser. Your files stay on your device throughout the conversion process-nothing is uploaded to external servers.

Pro Tip

When extracting audio from AVI for professional editing, check the source video's audio properties first. If the original was compressed with MP3 or AAC, converting to AIFF won't restore lost quality-it just stores the already-compressed audio in an uncompressed container. True quality preservation requires starting with high-quality source material.

Common Mistake

Choosing AIFF for files you only plan to stream or share casually. AIFF's 10 MB per minute file size is overkill for listening on phones or uploading to social media. Save AIFF for editing workflows where quality matters, and use MP3 or AAC for distribution.

Best For

Mac-based audio/video production workflows. If you're editing in Logic Pro, GarageBand, or Final Cut Pro, AIFF integrates perfectly without transcoding. It's also ideal when you need an archival-quality copy of audio extracted from video.

Not Recommended

When storage space is limited or you're preparing audio for web distribution. AIFF files are 10x larger than equivalent MP3 files. If you don't need to edit the audio or require bit-perfect quality, choose a compressed format instead.

Frequently Asked Questions

AIFF (Audio Interchange File Format) is an uncompressed audio format developed by Apple in 1988. It stores audio as PCM data without any compression, providing CD-quality sound. AIFF is widely used in professional audio production and is natively supported by all Mac applications.

No. AIFF is an uncompressed lossless format, so it preserves the full quality of the audio track from your AVI file. The only limitation is the quality of the original audio-we can't improve what's already compressed in the source video.

AIFF files are uncompressed, storing every audio sample without any compression. A minute of stereo CD-quality audio (44.1kHz, 16-bit) takes about 10 MB. This is the trade-off for perfect quality-no compression means larger files.

Yes. AIFF is Apple's native audio format and works seamlessly in Logic Pro, GarageBand, Final Cut Pro, and all other Apple audio/video applications. You can drag and drop AIFF files directly into any project.

Both AIFF and WAV store uncompressed PCM audio at identical quality. The main difference is origin: AIFF was created by Apple for Mac, while WAV was created by Microsoft for Windows. Most modern software supports both formats equally.

Choose AIFF when you need uncompressed quality for editing, mixing, or archiving. Choose MP3 when file size matters more than quality-for example, uploading to the web or storing on limited device storage. AIFF is about 10x larger than MP3.

Yes. Our converter supports batch processing. Upload multiple AVI files and convert them all to AIFF simultaneously. This is useful for processing video collections or extracting audio from multiple interview recordings.

Our converter handles all common audio codecs found in AVI files, including MP3, PCM, AC3, AAC, and others. The audio is decoded and re-encoded as uncompressed AIFF regardless of the original codec.

Yes. While AIFF was designed for Mac, it works on Windows too. Most Windows audio software including Audacity, Adobe Audition, and FL Studio can open AIFF files. Windows Media Player may require codec installation for playback.

No. All conversion processing happens locally in your browser using modern web technologies. Your video files never leave your device, ensuring privacy and eliminating upload wait times.
