OBS noise suppression filters garble music and must be removed when streaming DJ sets or live instruments

OBS ships with a noise suppression audio filter intended for voice (microphone) input. When this filter is applied to a music source — such as a DJ mixer or instrument routed through a soundboard — it treats musical content as noise and distorts or mutes it, producing garbled, altered audio. Users often troubleshoot hardware (mixer, cables, interface) for a long time without improvement because the problem is actually in OBS’s per-source audio filter chain, not the signal path. The fix is to open the audio source’s filter chain in OBS and delete the Noise Suppression filter; music then passes cleanly. Music sources need no noise suppression; EQ or a compressor are the appropriate filters if any processing is wanted.

Examples

Symptom: recording in a DAW from the same interface sounds perfect, but the OBS stream sounds garbled. Diagnosis: a Noise Suppression filter is active on the OBS audio source. Fix: Filters → select the audio source → delete Noise Suppression. Confirmed: ‘both the spoken voice and music … sound clear in our stream.‘
