This should be solved. The first 1/16th note and last 16/th note of a transition fade in/out.

Same audio, higher bitrate

Noticed that LAME VBR used a very low bitrate for parts of the audio. Uploading a new file using constant bitrate instead.

Sound leaking through spectral crossfader with flat envelope

When using spectral crossfade some sound will leak through from the subsequent track even if the flat envelope is used and the slider is kept all the way to the left. This does not seem to happen with the plain crossfader.
This is a minor issue, but it can in some cases cause the transition to start a bit abruptly.

Could it be a solution to also fade in the subsequent track from 0% to 2-3% of the transition (position of slider that is, not time into the transition), and fade out the previous track from 97-98% to 100%?

Attached file is a transition from silence to a new track using the spectral crossfader and flat envelope where the slider is kept all the way to the left during the entire transition.
