OBS microphone still distorts after lowering the fader

Make the comparison off-air

Do these comparisons off-air. Disabling a gate or suppression can expose room conversations. Write down the device gain, fader level, and filter settings; disable filters temporarily rather than deleting them. Keep any existing recording unchanged.

Separate loud playback from damaged voice

Record a normal sentence followed by the loudest voice you realistically use. Listen to the saved file at a comfortable volume. Play a known-clean recording through the same headphones as well.

If both files distort only when playback is loud, investigate the headphones, speakers, or playback level. If just the new voice recording sounds rough even at modest playback volume, follow its input path. If the problem is two overlapping copies of your voice, use the separate OBS echo checks.

Compare input and output, with filters bypassed

Identify the microphone's mixer row by speaking while other sources are quiet. Open its Filters from the Audio Mixer settings control and use each filter's eye icon to disable it temporarily. OBS's overview guide documents that control.

Watch the small input indicator at the far left of the microphone meter, as well as the moving output bar. OBS's meter reference places that input indicator before the fader but after source filters. Leaving a limiter or gain filter enabled can therefore obscure the unprocessed comparison.

Repeat the normal and louder sentence. An input indicator reaching white is close to full scale; red alone does not establish that audio has clipped. A quieter output bar after you move the fader does not show that the incoming signal became cleaner.

The table directs the next comparison; it does not diagnose a damaged cable or microphone from a meter alone.

Reduce the gain where the microphone enters the system

For an audio interface or microphone with a physical Gain control, reduce that input gain and repeat the louder sentence at the same distance. Use the device's meter or overload indicator if it has one. Do not compensate by moving much closer during the comparison.

For a Windows input controlled through the system, OBS's Audio Mixer Guide documents Control Panel > Hardware and Sound > Sound > Recording > your device > Properties > Levels. Note the existing level before reducing it. Device controls vary; on macOS, Linux, or an interface with its own control application, follow that device's input-level instructions rather than applying the Windows path.

The useful result is cleaner loud speech in a new recording, not simply a lower meter. If it remains distorted at a lower input level with processing bypassed, investigate the microphone or interface with its manufacturer before adding more OBS filters. New settings cannot repair clipped samples in an old file.

Add processing back without rebuilding the problem

Restore one filter at a time and record the same two sentences. A Gain filter adds level; a compressor's Output Gain can raise its processed result too. Compare those boosts before stacking another gain stage.

If distortion returns with Speex Noise Suppression, reduce its suppression or leave it bypassed for a comparison. The Noise Suppression reference warns that stronger Speex settings can distort voice. Missing quiet words need the more specific microphone-filter checks.

Once the input is clean, an OBS Limiter can contain later output peaks; OBS recommends placing it last in the filter chain. It cannot reconstruct a signal already damaged before that filter. Choose its threshold for your mix instead of treating its default as a calibrated microphone preset.

Restore the intended sources and listen to a short full recording before going live. For distortion that remains, use the OBS Help Portal with the device, OBS version, and whether bypassing filters or lowering device gain changed the saved voice. Keep private room audio out of any support sample.
