The standard converter that comes with the modtools uses an uncompressed format, which results in huge file sizes. I'll show you how to convert your sounds using ADPCM compression. You should see a decrease in file size by ~75%! You'll need this kit for conversion.

I should note that this is a modified version of
Megadeth9811's conversion_kit, however his used xWMA compression which is not as good as ADPCM.
Make sure you put your conversion_kit folder in a directory that has no spaces. Bad Example: C:\Users\Blah\Desktop\Mod Tools\conversion_kit
Good Example: C:\Users\Blah\Desktop\Modtools\conversion_kit
HOW TO CONVERT YOUR SOUND USING ADPCM COMPRESSION The steps that follow all take place in the conversion_kit folder, NOT in your WAW root.
1. Place your unconverted sounds into conversion_kit/sound_assets/raw/sound as you typically would.
2. Place your soundalias into conversion_kit/raw/soundaliases as you typically would.
3. Navigate to conversion_kit/bin and run convert.bat by just double-clicking it.

4. The converter will convert your sounds to Compressed ADPCM .WAV format, and your newly-converted sound files should show up in conversion_kit/raw/sound.
5. Your sounds are now converted in ADPCM format! You should notice a drastically lower file size compared to the standard uncompressed format. Now just remember to include your soundalias in a a zone_source file.
