When Should You Use AWB vs DFF?

AWB vs DFF: Key Differences

• •AWB uses lossy compression while DFF uses lossless compression — this is the fundamental technical difference between the two formats.
• •The switch from lossy compression to lossless compression means you preserve full quality at the expense of larger file sizes.
• •How transparency is handled: DFF supports transparency, so alpha information is preserved during conversion.
• •File sizes: AWB files typically range N/A and DFF files N/A.
• •AWB is optimized for hd voice calls, mobile speech recording while DFF is designed for audiophile music, high-resolution audio archiving — choose based on your specific workflow needs
