Audio Artifacts #50

image https://github.com/stemrollerapp/stemroller/assets/34815371/691dfd10-acf4-4977-b27f-d7bcac7169ed Ive noticed this very minor issue on generated audio files where background noise or other effects will be brought up very rapidly. There are multiple little lines of audio (in the image) that make a sort of rattling sound in your headphones when you listen to the track. As you can see in the image they occur very frequently in this one audio track. This issue is almost never seen on the "vocal" separation but very prominent on the "other" separation with less prominence but very mildly noticeable on the drums and bass too. It makes a sort of tv static or clicking sound. Not sure if this is fixable or not but thought id make an issue for it to point it out. Ive loved using Stemroller after switching from iZotope RX because it has so much more cleaner cuts and handles the audio easier. This however is the only drawback Ive come across and would like to make note of it, not sure if others have had this issue too. It was very obvious on this one specific audio track that I got back. Ive attacked a very short .mp4 containing only an short clip from the audio track of the issue.

Hmm... that is a very strange artifact. StemRoller is simply a frontend wrapper which delegates all audio processing to Demucs (https://github.com/facebookresearch/demucs), so the issue is probably with that application. Would you be able to try the latest version of Demucs directly, without StemRoller? Just follow the directions on that page linked earlier, and let me know if the issue still persists. If it does, feel free to file an issue on the Demucs project, otherwise let me know if the issue only exists when using StemRoller.
