Convert AVI to FLAC
What is AVI?
AVI
AVI (Audio Video Interleave) multiplexes audio and video data chunks in RIFF structure for synchronized playback. Audio streams typically use codecs like MP3, PCM, or AC3 at various bitrates. Extracting audio from AVI means demultiplexing the interleaved streams—separating audio chunks from video chunks. This is standard container operation, preserving audio quality without re-encoding if desired.
- AVI combines video and audio streams in a container, allowing audio track extraction
- Contains separate audio track easily extracted to FLAC format
- Video stream discarded—only audio codec and bitrate matter
What is FLAC?
FLAC
FLAC is audio-only codec without visual components. Video requires frame sequences with visual data. FLAC lacks video streams—creating video from FLAC audio requires adding visual elements like static images, album artwork, or animated visualizations. This requires video editing software combining lossless audio with generated or imported visuals.
- FLAC contains pure audio data requiring video track addition for video output
- Linear prediction compression maintains bit-perfect audio reproduction
- Modern format—requires up-to-date software for compatibility
