How do I convert an AVR file to SOU using this tool?

Click the upload area to select your .avr file or drag-and-drop it. Choose SOU from the output format list. Optionally adjust sample rate or channels if needed. Click 'Convert' and wait for the processing bar to finish. Download the resulting .sou file—your original is not uploaded and the converted file is ready instantly.

Why should I convert AVR to SOU instead of using AVR directly?

AVR is a proprietary format used by certain digital voice recorders, often with ADPCM compression. SOU is a simple uncompressed PCM container widely accepted by game engines, legacy Apple software, and embedded devices. Converting ensures compatibility and eliminates audio stutter caused by unsupported codecs. Because SOU is uncompressed, editing in audio editors is easier.

How does the conversion preserve audio quality from AVR to SOU?

The conversion decodes the AVR codec (typically IMA ADPCM or PCM) into a PCM buffer, then remuxes it into a .sou container with the identical sample rate, bit depth, and channel count from the source. If the source is ADPCM, the lost compression artifacts remain—conversion doesn't restore quality, but it does deliver a bit-exact PCM representation of the decoded stream. Metadata such as recording timestamps is not carried over.
