What is the difference between audio restoration and simply converting to WAV?

Simple WAV conversion does not add missing detail. Conversion in tools like Audacity mostly repackages existing samples through interpolation, while True Audio Restoration uses generative AI (similar to image super-resolution) to predict and insert missing detail, recovering dynamic range and "air" lost to compression.

Use Audio Restoration when the source is muffled, bandwidth-limited, clipped, or damaged by lossy compression. Read the MP3 upscaling guide for more context.
