About OGV to ALAC Conversion
OGV files store Vorbis audio (a lossy open-source codec) within the Ogg video container. ALAC (Apple Lossless Audio Codec) is Apple's lossless compression format that reduces PCM audio to about 50-60% of original size with zero data loss. Open-sourced by Apple in 2011, ALAC plays natively on every Apple device and integrates seamlessly with Apple Music, iTunes, and Apple's professional audio tools.
Why Convert OGV to ALAC?
Extracting OGV audio to ALAC creates a lossless archival copy of the decoded Vorbis audio that integrates perfectly with the Apple ecosystem. While the source is lossy (Vorbis), storing the decoded output as ALAC prevents any further quality degradation during future format conversions or editing.
ALAC is also the best format for importing into Apple Music with the Lossless quality badge, making it ideal for building a music library from OGV video sources.
Common Use Cases
- Archiving conference talk audio from OGV recordings in Apple's lossless format for long-term preservation
- Extracting music from OGV concert videos for Apple Music library integration with lossless quality
- Creating lossless audio masters from OGV sources for future re-encoding to any lossy format
- Building an Apple-native audio library from open-source OGV video content
- Extracting OGV audio for lossless storage on iCloud Drive with full Apple ecosystem integration
How It Works
FFmpeg decodes the OGV container's Vorbis audio to raw PCM, then encodes using the ALAC encoder into an M4A container. The output supports 16-bit to 32-bit depth and sample rates up to 384 kHz. Typical OGV Vorbis audio at 44.1 kHz stereo maps directly to 16-bit/44.1 kHz ALAC. Compression achieves roughly 50-60% of the PCM equivalent size while remaining bit-perfect on decode.
Quality & Performance
ALAC losslessly preserves the decoded Vorbis audio. Since Vorbis is lossy, the ALAC output contains the same quality as the Vorbis source — no better, no worse. The advantage is that ALAC prevents any further quality loss during subsequent operations while providing meaningful compression savings versus uncompressed WAV or AIFF.

Tips for Best Results
- 1Extract at 16-bit/44.1 kHz to match the Vorbis source — higher bit depths waste space without adding quality
- 2Use ALAC as your master archival copy and derive AAC/MP3 versions from it to avoid lossy-to-lossy transcoding
- 3Add proper metadata (title, artist, album, artwork) for clean Apple Music library display
- 4If you need cross-platform lossless, also create a FLAC copy — some devices do not support ALAC
- 5Tag the file accurately to avoid confusion — note in the comments that the source is OGV Vorbis
