Convert ASF to AIFF — Free Online Converter

AIFF (Audio Interchange File Format) is Apple's uncompressed audio standard, storing PCM waveform data at full CD quality or higher. ASF files from Windows Media environments typically carry WMA-compressed audio. Converting ASF to AIFF decodes the compressed WMA stream and writes raw PCM samples, preserving every detail the WMA codec retained — ideal for professional audio workflows on macOS.

AIFF is the professional audio standard on Apple platforms, natively supported by Logic Pro, GarageBand, and Final Cut Pro without any codec dependencies. When you need to bring audio from a Windows Media recording into a Mac-based production pipeline, AIFF ensures zero additional quality loss from that point forward. AIFF also supports metadata chunks and loop points, making it useful for sound design.
