What is an AVI file?

Audio Video Interleave (AVI) is a multimedia container format introduced by Microsoft in 1992 as part of the Video for Windows technology. It adheres to the Resource Interchange File Format (RIFF) specification, storing audio and video data in tagged chunks (specifically 'movi' lists) to allow synchronous playback. While widely compatible, the legacy AVI architecture lacks native support for modern features found in MP4 or MKV, such as variable frame rates (VFR), B-frames, and sophisticated chapter markers. It typically utilizes codecs like DivX, Xvid, or MJPEG.

How to open an AVI file

AVI files enjoy broad compatibility on Windows via Windows Media Player. However, because AVI is a container that can hold various codecs (e.g., DivX, Xvid), playback may fail if the specific codec is missing. macOS users can view AVI files using QuickTime Player if the content is MJPEG, but third-party players are often required for other codecs. VLC media player and MPC-HC are standard recommendations for handling the vast array of codecs potentially encapsulated within an AVI file.

What is a WAV file?

The Waveform Audio File Format (WAV) is a raw audio bitstream standard developed by Microsoft and IBM, serving as a subset of the Resource Interchange File Format (RIFF) specification. It primarily stores uncompressed Linear Pulse Code Modulation (LPCM) audio data, making it the industry standard for archival and high-fidelity mastering on Windows systems. The format supports varying bit depths and sample rates, with the Red Book standard (44.1 kHz, 16-bit stereo) being the most prevalent implementation.

How to open a WAV file

WAV files enjoy near-universal native support across all major operating systems due to their status as a foundational audio standard. Windows Media Player, Apple QuickTime, and Linux-based media players (via ALSA/PulseAudio) open WAV files by default without requiring external codec packs or third-party software.
