AVI files store audio in a variety of codecs, and WMA (Windows Media Audio) is Microsoft's proprietary lossy audio codec, introduced in 1999 as a competitor to MP3 and RealAudio. WMA Standard operates at bitrates from 32 to 320 kbps, using a modified discrete cosine transform (MDCT) similar to AAC. WMA was the default audio format for Windows Media Player, Zune, and Microsoft's digital media ecosystem through the Windows XP/Vista era. Converting AVI to WMA extracts the audio track and encodes it in Microsoft's format for Windows-centric playback.
WMA remains embedded in certain Windows-based workflows, car stereo head units (many support WMA but not AAC), and legacy Microsoft media libraries. If you have an existing WMA-based music library in Windows Media Player or need to produce audio for a car stereo that lists WMA support, this conversion provides compatible output. WMA at 128 kbps was historically considered competitive with MP3 at 160 kbps, though modern codecs (AAC, Opus) have surpassed both.
FFmpeg extracts the audio from the AVI container, decodes it to PCM, and re-encodes to WMA v2 (wmav2 codec) at the selected bitrate (typically 128–192 kbps for stereo). The output is wrapped in an ASF (Advanced Systems Format) container with the .wma extension. WMA supports sample rates up to 48 kHz and stereo or mono channel configurations. WMA Pro and WMA Lossless are also available for higher quality needs.
WMA at 128 kbps is generally considered comparable to MP3 at 160 kbps — good for casual listening. At 192 kbps, WMA sounds very clean for most content. Below 96 kbps, WMA's quality degrades with characteristic warbling artifacts on cymbals and sibilants. For critical listening, AAC or Opus at the same bitrate will outperform WMA.
