Convert AVI to WMA — Free Online Converter

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.
