WMA is Microsoft's audio codec in the ASF container. AVI (Audio Video Interleave), also a Microsoft RIFF-based container from 1992, interleaves audio and video data in alternating chunks. Both are Microsoft formats from different eras.
Converting WMA to AVI wraps the audio inside an AVI container, typically for compatibility with legacy video editing software, older Windows applications, or hardware devices that only accept AVI input.
Some legacy video editing systems (VirtualDub, older Windows Movie Maker) and industrial media players only accept AVI. CCTV systems and surveillance hardware often use AVI exclusively. Converting WMA audio to AVI enables integration with these legacy systems.
AVI is also required when combining audio with video in workflows that predate modern container formats. Industrial automation, embedded systems, and specialized hardware players may only support AVI.
FFmpeg decodes the WMA stream from ASF and encodes to MP3 or PCM within an AVI RIFF container. AVI uses a simple index for seeking and interleaves audio chunks throughout the file. Since WMA cannot be stored directly in AVI, transcoding to MP3 or PCM is required.
Encoding to PCM in AVI preserves the full decoded WMA quality losslessly. Encoding to MP3 in AVI introduces generation loss from WMA-to-MP3 transcoding. The AVI container itself adds no quality impact.
