Convert FLV to AIFF — Free Online Converter

FLV (Flash Video) stores audio as compressed MP3, AAC, or Nellymoser within Adobe's streaming container. AIFF (Audio Interchange File Format) is Apple's uncompressed PCM audio standard, storing raw waveform data at full CD quality (16-bit/44.1 kHz) or higher. Developed by Apple in 1988 based on the IFF format from Electronic Arts, AIFF is the Mac equivalent of WAV and is the preferred import format for professional DAWs like Logic Pro, Pro Tools, and GarageBand. Converting FLV to AIFF gives you lossless, editor-friendly audio from legacy Flash content.

Professional audio workflows on macOS rely on AIFF as the native uncompressed format. If you have FLV recordings containing music, voice-overs, or sound effects, converting to AIFF provides a lossless working copy that can be edited, processed, and mixed without introducing additional compression artifacts. AIFF also supports metadata chunks for loop points and instrument definitions used in music production.
