What is FLAC?

FLAC (Free Lossless Audio Codec) provides lossless compression of digital audio without any quality loss, reducing file size by 50-60%.

What is DSS?

Olympus DSS (Digital Speech Standard) is a compressed voice recording format used in Olympus dictation devices for professional transcription.

When Should You Use FLAC vs DSS?

FLAC vs DSS: Key Differences

• •FLAC and DSS diverge on compression: lossless compression for the source, lossy compression for the target.
• •Converting from FLAC to DSS changes compression type: lossy source becomes smaller but with some quality tradeoff.
• •Transparency: N/A — converting from FLAC will merge transparency into a solid background
• •File sizes: FLAC files typically range 5MB per minute at CD quality and DSS files Compact, hours of recording in small files.
• •Primary audience: FLAC is built for archival audio, audiophile listening scenarios, while DSS focuses on voice dictation, professional transcription — pick the format that matches your output requirement.
