When Should You Use VOC vs RA?

Use VOC When...

VOC shines in legacy dos audio, retro computing scenarios. The pixel-perfect output meets the demands of professional production environments.

Use RA When...

Reach for RA when your priority is legacy streaming audio, internet radio — its efficient compression makes sharing fast and storage minimal.

VOC vs RA: Key Differences

  • •The core technical difference: VOC relies on lossless compression whereas RA uses lossy compression.
  • •The switch from lossless compression to lossy compression means you gain significant space savings while accepting minor quality trade-offs.
  • •Transparency: N/A — converting from VOC will merge transparency into a solid background
  • •File sizes: VOC files typically range Similar to WAV for PCM audio and RA files Very small, for streaming.
  • •Primary audience: VOC is built for legacy dos audio, retro computing scenarios, while RA focuses on legacy streaming audio, internet radio — pick the format that matches your output requirement.

Best Practices for VOC to RA Conversion

  • →For VOC to RA: 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
  • →RA 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
