Obviously the forum has no effect on the sound as you are simply linking to SC and that is where the listener gets their stream independent of any forum influence. FWIW, I and likely you also submit only wav files to SC. They will crush an mp3 sometimes. Also if after uploading I hear artifacts I replace the file with another copy of the same and it sometimes sounds better. BTW, SC is one of the very few major streaming platforms that doesn't raise or reduce the gain of your song. With my marginal hearing I have to be very careful when listening to SC as some users upload extremely loud tunes. Yours always sound quite comfortable and at the streaming volume of Spotify, Apple, etc. Not to get off base any further smile but one can drop a song onto loundnesspenalty's web page and without signing up or uploading the song it will instantly be analyzed and give you info on to what degree, if any, the major platforms will modify it.
