WMVからAIFFへの変換について
WMV's ASF container stores audio using WMA codecs — WMA Standard (lossy, up to 320 kbps) or WMA Lossless (bit-perfect). AIFF (Audio Interchange File Format) is Apple's uncompressed audio standard, storing raw PCM data at CD quality (16-bit/44.1 kHz) or higher resolutions (24-bit/96 kHz). Converting WMV to AIFF extracts the audio track from Microsoft's proprietary container and writes it as lossless, uncompressed PCM in Apple's format, ready for Logic Pro, GarageBand, and professional macOS audio workflows.
WMVをAIFFに変換する理由
When bringing audio from WMV recordings into Apple's audio production ecosystem, AIFF is the native lossless format. Logic Pro, GarageBand, Final Cut Pro, and Soundtrack Pro all read AIFF with zero conversion overhead. AIFF also natively supports rich metadata (ID3v2 tags) and is the standard for macOS system sounds, sample libraries, and pro audio interchange on Mac.
主な活用例
- Extracting dialogue from WMV video for editing in Logic Pro X
- Creating lossless audio masters from WMV recordings of live performances
- Preparing voiceover tracks from WMV presentations for Final Cut Pro timelines
- Archiving the audio from WMV files in Apple's lossless format for long-term preservation on Mac
- Isolating sound effects from WMV game or event recordings for use in macOS sample libraries
仕組み
FFmpeg opens the ASF container, decodes WMA audio to raw PCM, and writes it into an AIFF container with big-endian signed integer PCM encoding. The sample rate (44.1/48/96 kHz), bit depth (16/24-bit), and channel layout from the WMA source are preserved. If the WMV uses WMA Lossless, the extraction produces a bit-perfect AIFF copy of the original audio.
品質とパフォーマンス
AIFF is uncompressed PCM — it introduces zero quality loss. If the WMV source uses WMA Lossless, the AIFF is bit-perfect. If the source uses standard WMA (lossy), the AIFF preserves the full decoded quality without further degradation. Converting lossy WMA to AIFF does not restore detail lost in the original WMA encoding.

最良の結果を得るためのヒント
- 1If the WMV contains WMA Lossless audio, the AIFF extraction is bit-perfect — ideal for archival purposes.
- 2For editing in Logic Pro, AIFF at 48 kHz/24-bit is the standard project format — check if your WMV source matches this spec.
- 3Consider ALAC instead of AIFF if file size matters — ALAC provides identical quality at roughly half the size.
- 4Add proper ID3v2 tags to the AIFF output for organization in Apple's Finder and iTunes.
