What is MP2?

MPEG Layer II (MP2) is an audio codec standard in broadcast and DVD, offering robust compression for professional use.

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 MP2 vs SND?

Use MP2 When...

Reach for MP2 when your priority is broadcast audio, dvd audio tracks, legacy video — its efficient compression makes sharing fast and storage minimal.

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.

MP2 vs SND: Key Differences

  • •MP2 and SND diverge on compression: lossy compression for the source, lossless compression for the target.
  • •The switch from lossy compression to lossless compression means you preserve full quality at the expense of larger file sizes.
  • •Alpha channel support: SND lacks transparency support.
  • •MP2 files are typically Smaller than uncompressed, 128-384kbps while SND files range Small to medium, similar to uncompressed WAV
  • •Primary audience: MP2 is built for broadcast audio, dvd audio tracks, legacy video scenarios, while SND focuses on unix sound effects, legacy sun audio files — pick the format that matches your output requirement.

Advantages of MP2

  • ✓The lossy nature of MP2 means file sizes stay reasonable while handling Broadcast audio, DVD audio tracks, legacy video efficiently.
  • ✓From mobile devices to enterprise servers, MP2 is recognized and supported everywhere.
  • ✓Storage and bandwidth costs drop significantly when using MP2 thanks to its efficient compression.
  • ✓MP2 is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of SND

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

Troubleshooting MP2 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 MP2 file before converting to avoid unnecessary padding
  • !Stereo image collapsed after converting MP2 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

Does converting MP2 to SND lose quality?

No, converting MP2 to SND does not cause additional quality loss — SND uses lossless compression. However, any artifacts already present in the original MP2 file will persist in the SND output.

What file size should I expect after converting MP2 to SND?

SND files are typically 2-5x larger than equivalent MP2 files because SND preserves all pixel data. This is expected and necessary for lossless quality.
