What is TTA?

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

What is SND?

Sun Sound (SND) is a basic Unix audio format for simple sound effects and system sounds on Sun workstations.

When Should You Use TTA vs SND?

Use TTA When...

Reach for TTA when your priority is lossless audio compression, archival — its uncompromising quality ensures every detail is preserved.

Use SND When...

Reach for SND when your priority is unix sound effects, legacy sun audio files — its uncompromising quality ensures every detail is preserved.

TTA vs SND: Key Differences

  • •TTA and SND diverge on compression: lossless compression for the source, lossless compression for the target.
  • •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •How transparency is handled: SND supports transparency, so alpha information is preserved during conversion.
  • •File sizes: TTA files typically range 40-50% smaller than WAV and SND files Small to medium, similar to uncompressed WAV.
  • •TTA is optimized for lossless audio compression, archival while SND is designed for unix sound effects, legacy sun audio files — choose based on your specific workflow needs

Advantages of TTA

  • ✓At its core, TTA relies on lossless encoding — a design choice that makes it perfect for Lossless audio compression, archival.
  • ✓You won't run into compatibility issues with TTA — it's a universal standard across platforms.
  • ✓File size management with TTA: larger files guaranteed to match the original exactly.
  • ✓Every major application in the Lossless audio compression, archival space supports TTA natively.

Advantages of SND

  • ✓SND compresses data using lossless methods, keeping file sizes manageable for Unix sound effects, legacy Sun audio files.
  • ✓Industry-wide support means SND files open anywhere — from legacy systems to the latest devices.
  • ✓Lossless quality makes SND the gold standard for archival and master copies.
  • ✓From professional software to open-source alternatives, SND works out of the box.

Troubleshooting TTA to SND Conversion

  • !Clicks or pops in the converted SND → sample rate conversion can introduce artifacts; use a clean multiple of the source rate
  • !SND file has silence at the beginning or end → trim the source TTA file before converting to avoid unnecessary padding
  • !Stereo image collapsed after converting TTA to SND → verify that the converter preserves channel mapping for multichannel audio
  • !The converted SND clips or distorts at peaks → reduce the gain or apply a limiter before conversion to prevent hard clipping
