Low-End Phase Problems: Diagnose Before Processing
Illustration: WBBT Records.
Phase relationships vary over time and frequency; a polarity switch is only one diagnostic tool. Layered kicks and bass can cancel or build up differently across a track.
Put it into practice
Listen in mono, isolate the sources and compare their envelopes. Try timing and arrangement changes, then verify the result across the full section rather than one waveform view.
Check the finished deliverable
Keep the original session and compare the final export with your approved reference. Listen from start to finish, including transitions and the tail. Check that the file you upload is the intended version, not an earlier bounce with a similar name. If the release needs a specialist format, get the delivery specification before the final export.
Your next step
Listen in mono, isolate the sources and compare their envelopes. Keep a short record of the decision and revisit it after your next completed project.
Prepare an audio release for the relevant WBBT Records workflow.
