FLV (Flash Video) typically carries MP3 or AAC audio within Adobe's container. WMA (Windows Media Audio) is Microsoft's proprietary audio codec family, first released in 1999 as part of the Windows Media framework. WMA Standard uses perceptual coding at 32-192 kbps, while WMA Professional supports up to 768 kbps with surround sound. WMA files integrate natively with Windows Media Player, Windows Explorer, and Xbox consoles. Converting FLV to WMA extracts audio in Microsoft's native format.
WMA is deeply integrated into the Windows ecosystem — Windows Media Player, Groove Music, Windows Explorer preview, and Xbox all handle WMA natively. For Windows-centric workflows, WMA files provide seamless integration including album art display, metadata, and DRM support. WMA at 128 kbps delivers quality competitive with MP3 at 160 kbps, offering a slight efficiency advantage.
FFmpeg decodes the FLV audio stream and re-encodes using the wmav2 encoder (WMA version 2) at specified bitrate. WMA uses MDCT-based perceptual coding with Bark-scale frequency band allocation. Output supports sample rates up to 48 kHz stereo. The resulting .wma file uses the ASF (Advanced Streaming Format) container with Windows Media Audio codec identifier. WMA Professional (wmapro) is available for higher quality at 256+ kbps.
WMA Standard at 128 kbps is comparable to MP3 at 160 kbps — slightly more efficient at low bitrates. At 192 kbps, WMA is perceptually transparent for most content. WMA Professional at 256 kbps provides quality rivaling lossless for most listeners. Transcoding from FLV's compressed audio introduces a small generation loss, so using a higher output bitrate (192+ kbps) is recommended.
