Thank you, that was exactly our intent! Right now, the OGG format is more readily accessible since it's the standard for engines.
While the compressed OGG files are very usable, they do have some quality loss compared to WAV files due to the compression. WAV files are uncompressed, so they provide higher fidelity audio, which can make a noticeable difference, especially in terms of clarity and richness in voice acting. We plan to release WAV alternatives in the coming weeks for those who want the best possible sound quality, but for now, we hope the OGG files serve you well!
