• •Converting from DSS to AIFF changes compression type: lossless source becomes larger but with full quality preservation.
• •How transparency is handled: AIFF supports transparency, so alpha information is preserved during conversion.
• •File sizes: DSS files typically range Compact, hours of recording in small files and AIFF files 10MB per minute at CD quality.
• •DSS is optimized for voice dictation, professional transcription while AIFF is designed for professional audio production, music recording — choose based on your specific workflow needs
