Description

Hi! I have a weird issue where I always get some cracking sound every few seconds after separating vocals and instrumental + vocals. Cracking is present on both files. For the track in the attachment, you can start hearing it after 00:16. To me it sounds like bass is making a problem but I am not certain.

Research direction
Investigate the cracking sound by analyzing the provided audio file (Lav.flac). The issue mentions the sound starts around 00:16 and suggests bass may be involved. Examine the source separation module in the codebase for any bugs related to low frequency handling. Check for clipping in the output or phase cancellation issues. Consider testing with other audio samples to rule out sample specific problems.
