Convert AVI to AIFF — Free Online Converter

AVI's RIFF container can hold audio in many codecs — PCM, ADPCM, MP3, AC3, or even DTS. AIFF (Audio Interchange File Format) is Apple's uncompressed audio standard, developed in 1988 based on Electronic Arts' IFF structure. AIFF stores linear PCM data at full resolution (16-bit/44.1 kHz CD quality or higher), making it the macOS and Logic Pro equivalent of WAV. Converting AVI to AIFF extracts the audio track and writes it as lossless, uncompressed PCM in Apple's container format.

Professionals working in Apple-centric audio production environments — Logic Pro, GarageBand, Final Cut Pro — prefer AIFF as their native lossless format. When extracting audio from AVI footage for mixing, mastering, or sound design, AIFF ensures zero quality loss and seamless integration with macOS audio tools. Unlike WAV, AIFF natively supports metadata chunks (ID3 tags) for titling and annotation.
