It would be nice to add a toggle to check both mid/side spectrograms. A lot of spectrograms can be false due to how new codecs work, and they can be revealed if they're actually high quality by checking the side. A YouTube OPUS for example, shows up to 20khz, but if you use the Audacity center removal feature and load it in Spek, it would just go up to about 16khz.
