Your current audio is 192kbps with 16.5KHz which isn't the best quality possible (also if it's around 16KHz it should be encoded to 128kbps and we don't want that). Heres a link to download a 192kbps with 19.1KHz that looks way better in Spectro!

(Timing is 97 not 97,1 and with this new audio you have to move everything -55ms and resnap objects)
