What happens when converting AAC to WAV?
The AAC data is decoded inside your browser with WebAssembly and re-encoded to the WAV specification, so no file is ever uploaded to a server. WAV uses lossy compression: the file gets far lighter, but a small amount of fine detail is discarded in the process.
