WMA encompasses three codec variants: WMA Standard (lossy, 32-320 kbps), WMA Pro (multichannel lossy), and WMA Lossless (bit-perfect compression). FLAC (Free Lossless Audio Codec) is the universal open-source lossless audio standard, supported natively on Android, Linux, Windows 10+, and most music streaming platforms. FLAC achieves 50-60% compression compared to raw PCM.
Converting WMA to FLAC moves your audio from Microsoft's proprietary ecosystem to the most widely supported open lossless format. For WMA Lossless sources, this is a perfect lossless-to-lossless transfer. For WMA Standard sources, FLAC preserves the decoded audio at its current quality level.
FLAC is the industry standard for lossless music distribution and archiving. Bandcamp, Tidal, Qobuz, Amazon Music HD, and Deezer HiFi all use FLAC. Converting WMA to FLAC future-proofs your music library in an open, patent-free format that will be supported indefinitely.
FLAC's metadata capabilities far exceed WMA's. Vorbis comment tags support virtually unlimited custom fields, embedded album art, ReplayGain values, and cue sheets. For music collectors migrating from Windows Media Player, FLAC provides a superior organizational framework.
FFmpeg demuxes the ASF container, decodes the WMA audio (Standard, Pro, or Lossless) to PCM, and encodes using the FLAC encoder. FLAC compression levels 0-8 trade encoding speed for file size without affecting quality. The encoder uses linear prediction and Rice coding to achieve lossless compression. The output preserves the source sample rate, bit depth, and channel layout. An MD5 checksum of the decoded audio is stored in the FLAC header for integrity verification.
FLAC encoding is mathematically lossless. For WMA Lossless sources, the entire conversion is end-to-end lossless — the FLAC output is bit-for-bit equivalent to the original pre-compression audio. For WMA Standard sources, FLAC perfectly preserves the decoded lossy audio at whatever quality WMA retained. No additional quality loss occurs during FLAC encoding.
