Question about storage quota and my audio. Possibly bug

So, upon uploading a song to roll20 in the new My Audio feature for the jukebox the info above the file icon shows that its 12MB. I have 51 MB of 100MB used up acording to the recent uploads page. Upon uploading I check and see that now I have 53MB. Im not very good at math but it should be 63 right. am I missing something? This has me quite worried. I dont want to discover later that I have reached my 100Mb by accident because of a misscount

Audio files are converted to a smaller format on upload. What format was your file when you started?
