What is VOX?

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

What is 3GA?

3GA files are built around lossy compression. Designed for mobile voice recordings, phone memos, they use the audio/3gpp MIME type and typically range from varies by content.

When Should You Use VOX vs 3GA?

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 3GA When...

VOX vs 3GA: Key Differences

  • •The core technical difference: VOX relies on lossy compression whereas 3GA uses lossy compression.
  • •Neither format changes compression philosophy — both are lossy compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
  • •Transparency: Not supported in 3GA
  • •3GA files tend to be differently sized than VOX
  • •VOX is optimized for telephone systems, voice mail, ivr systems while 3GA is designed for mobile voice recordings, phone memos — choose based on your specific workflow needs

Troubleshooting VOX to 3GA Conversion

  • !Clicks or pops in the converted 3GA → sample rate conversion can introduce artifacts; use a clean multiple of the source rate
  • !3GA file has silence at the beginning or end → trim the source VOX file before converting to avoid unnecessary padding
  • !Stereo image collapsed after converting VOX to 3GA → verify that the converter preserves channel mapping for multichannel audio
  • !The converted 3GA clips or distorts at peaks → reduce the gain or apply a limiter before conversion to prevent hard clipping
