Why convert MP3 to WAV? Because it plays on anything ever made, while it keeps every bit of the sound with no compression at all. The file is decoded by your browser and encoded again as WAV, so nothing is uploaded and there is no queue.

WAV stores the decoded audio exactly, so nothing is lost after decoding. Expect about ten megabytes per minute of stereo audio.
