What is VOX?

Dialogic VOX is a compressed speech audio format optimized for telephony systems, voice mail, and interactive voice response.

What is VOC?

Creative Voice (VOC) is a legacy audio format developed by Creative Labs for their Sound Blaster sound cards.

When Should You Use VOX vs VOC?

Use VOX When...

Reach for VOX when your priority is telephone systems, voice mail, ivr systems — its efficient compression makes sharing fast and storage minimal.

Use VOC When...

Reach for VOC when your priority is legacy dos audio, retro computing — its uncompromising quality ensures every detail is preserved.

VOX vs VOC: Key Differences

  • •VOX uses lossy compression while VOC uses lossless compression — this is the fundamental technical difference between the two formats.
  • •Converting from VOX to VOC changes compression type: lossless source becomes larger but with full quality preservation.
  • •Transparency: N/A
  • •Storage footprint: Very small, ideal for voice storage for VOX vs Similar to WAV for PCM audio for VOC.
  • •Primary audience: VOX is built for telephone systems, voice mail, ivr systems scenarios, while VOC focuses on legacy dos audio, retro computing — pick the format that matches your output requirement.

Advantages of VOX

  • ✓At its core, VOX relies on lossy encoding — a design choice that makes it perfect for Telephone systems, voice mail, IVR systems.
  • ✓You won't run into compatibility issues with VOX — it's a universal standard across platforms.
  • ✓File size management with VOX: aggressive compression with minimal visible quality loss.
  • ✓Every major application in the Telephone systems, voice mail, IVR systems space supports VOX natively.

Advantages of VOC

  • ✓VOC applies lossless compression specifically calibrated for Legacy DOS audio, retro computing.
  • ✓VOC enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓VOC guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find VOC support built into virtually every tool that handles Legacy DOS audio, retro computing — no plugins or converters needed.

Best Practices for VOX to VOC Conversion

  • →For VOX to VOC: match the sample rate and bit depth to your delivery platform — 44.1 kHz / 16-bit is the standard for music
  • →Apply loudness normalization (LUFS) before conversion to ensure consistent volume across your audio library
  • →VOC prioritizes quality — ensure your storage can accommodate the resulting file sizes
  • →Check that metadata tags (artist, album, track number) survive the conversion
  • →Convert a short segment first to verify quality at your chosen bitrate
  • →Keep a lossless master copy in case you need to re-encode for a different platform

Troubleshooting VOX to VOC Conversion

  • !VOC audio quality degraded vs VOX → use a higher bitrate (at least 256 kbps for music)
  • !VOC file won't play on your device → check format compatibility with your player or platform
  • !Metadata (artist, album, title) lost after VOX to VOC conversion → some formats like VOC may not support ID3 tags
  • !Volume changed after converting VOX to VOC → normalize audio levels before conversion for consistent playback
