What is DFF?

DSDIFF, Direct Stream Digital audio for SACD and high-res audio — stored as audio/x-dff — uses lossless encoding to handle audiophile music, high-resolution audio archiving. Typical file sizes: varies by content.

What is TTA?

True Audio (TTA) is a free, real-time lossless audio codec that provides efficient compression without compromising audio quality.

When Should You Use DFF vs TTA?

DFF vs TTA: Key Differences

• •DFF and TTA diverge on compression: lossless compression for the source, lossless compression for the target.
• •Since both DFF and TTA use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Transparency: N/A
• •TTA files tend to be differently sized than DFF
• •DFF is optimized for audiophile music, high-resolution audio archiving while TTA is designed for lossless audio compression, archival — choose based on your specific workflow needs
