ASF to VOC Converter

Convert ASF files to VOC. Free, without uploading.

This tool converts ASF files to VOC. Advanced Systems Format.

Creative Voice audio. Only the audio of the ASF video is kept and saved as VOC; the picture is dropped. VOC is lossless, so the audio keeps the quality it has in the ASF file.

Conversion runs on your device; your file is never sent to a server. The components download once on first use, and later conversions start right away.

How to use

1. Choose the ASF video, drag it in, or paste its link.
2. Choose the audio quality; optionally enter a start and end time.
3. Press "Convert" and download the VOC file.
