What is VOC?

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

What is 3GA?

3GA (audio/3gpp) uses lossy compression optimized for mobile voice recordings, phone memos. 3GPP Audio, compressed audio from mobile phone recordings

When Should You Use VOC vs 3GA?

Use VOC When...

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

Use 3GA When...

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

VOC vs 3GA: Key Differences

  • •VOC uses lossless compression while 3GA uses lossy compression — this is the fundamental technical difference between the two formats.
  • •The switch from lossless compression to lossy compression means you gain significant space savings while accepting minor quality trade-offs.
  • •Alpha channel support: 3GA handles transparency, so semi-transparent pixels from the source will be lost.
  • •File sizes: VOC files typically range Similar to WAV for PCM audio and 3GA files N/A.
  • •VOC is optimized for legacy dos audio, retro computing while 3GA is designed for mobile voice recordings, phone memos — choose based on your specific workflow needs

Advantages of VOC

  • ✓VOC uses lossless compression tailored for Legacy DOS audio, retro computing.
  • ✓VOC is supported natively on virtually every device, browser, and operating system.
  • ✓VOC files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓VOC integrates seamlessly with all major creative tools and workflows.

Advantages of 3GA

  • ✓3GA compresses data using lossy methods, keeping file sizes manageable for Mobile voice recordings, phone memos.
  • ✓Industry-wide support means 3GA files open anywhere — from legacy systems to the latest devices.
  • ✓Small file sizes make 3GA ideal for email, web uploads, and cloud storage.
  • ✓From professional software to open-source alternatives, 3GA works out of the box.

Best Practices for VOC to 3GA Conversion

  • →For VOC to 3GA: 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
  • →3GA 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 VOC to 3GA Conversion

  • !3GA audio quality degraded vs VOC → use a higher bitrate (at least 256 kbps for music)
  • !3GA file won't play on your device → check format compatibility with your player or platform
  • !Metadata (artist, album, title) lost after VOC to 3GA conversion → some formats like 3GA may not support ID3 tags
  • !Volume changed after converting VOC to 3GA → normalize audio levels before conversion for consistent playback

FAQs

Is converting VOC to 3GA free?

Yes, GoConvertFile offers free conversion of VOC to 3GA for files up to 100MB. No registration required.

How long does it take to convert VOC to 3GA?

Most VOC to 3GA conversions complete within seconds for standard-sized files. Larger files may take longer depending on the conversion complexity.

What is 3GA best used for?

3GA is ideal for mobile voice recordings, phone memos. 3GPP Audio, compressed audio from mobile phone recordings

Does converting VOC to 3GA lose quality?

Yes, converting VOC to 3GA uses lossy compression, which reduces file size by discarding some visual data. Set quality to 85-95% for a good balance of quality and file size.

What file size should I expect after converting VOC to 3GA?

3GA files are typically 50-80% smaller than VOC files because 3GA uses efficient lossy compression. The exact reduction depends on quality settings.
