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.

What is VOX?

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

When Should You Use 3GA vs VOX?

Use 3GA When...

Reach for 3GA when your priority is mobile voice recordings, phone memos — its efficient compression makes sharing fast and storage minimal.

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.

3GA vs VOX: Key Differences

  • •3GA uses lossy compression while VOX uses lossy compression — both take the same approach to file size management.
  • •Both formats share lossy compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •Transparency: N/A
  • •Storage footprint: varies for 3GA vs Very small, ideal for voice storage for VOX.
  • •3GA is optimized for mobile voice recordings, phone memos while VOX is designed for telephone systems, voice mail, ivr systems — choose based on your specific workflow needs

Troubleshooting 3GA to VOX Conversion

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