Stream Audio Setup: How to Make Your Mic Sound Good in Meld and OBS

Real talk: viewers forgive a soft picture. They do NOT forgive bad audio. A buzzing, echoing, whisper-quiet mic ends streams faster than any other problem. The good news — the fixes are simple, and both Meld and OBS have the tools built in.

The four jobs of stream audio

1. Pick the right mic (the app must listen to the device you think it is)
2. Set your level (loud enough, never distorting)
3. Clean the room up (fans, keyboards, echo)
4. Hear yourself safely (headphones, not speakers — speakers feed the mic and your viewers hear everything twice)

Whichever app you run: normal speaking voice should bounce the meter in the green into yellow. Living in the red means clipping — that crunchy distortion nobody can un-hear.

In Meld Studio ⭐

Add and level your mic

1. In the Audio Mixer, click + to add a track and choose your microphone.
2. Talk at stream volume; set the track fader so peaks touch yellow, not red.
3. Tracks are per-scene aware: a classic setup mutes the mic on "Starting Soon" and "BRB" scenes while it stays live on your main scene. Your voice, your rules.

Kill the fan and the keyboard: Voice Clarity

1. On your mic track, click the + in the filters rack.
2. Add Voice Clarity. (Older Meld versions: Magic Mic — same job.)
3. Pick a strength — start at Moderate. Too high can nibble the ends of your words; too low leaves the fan. Moderate is the honest middle.
4. Voice Clarity also has automatic gain: it rides your volume for you, so quiet talk stays hearable and a laugh doesn't blow the doors off.

Music ducking: Compression

Want game or music to dip under your voice automatically?

1. Add the Compression filter to the GAME or MUSIC track (not the mic).
2. Set your microphone as the sidechain.
3. Now when you talk, that track dips; when you stop, it fades back. Adjust how fast it fades back until it feels natural.

Hear yourself: CUE

Turn on CUE on a track to monitor it in your headphones. CUE is your ears only — it doesn't change what viewers hear. Keep monitoring in headphones, always.

In OBS Studio

Set the mic

1. Settings → Audio → Mic/Auxiliary Audio = your microphone.
2. Sample Rate: 48 kHz. Then open your system sound settings and set the mic's format to 48 kHz there too ("2 channel, 24 bit, 48000 Hz" on Windows). Mismatched rates = slow drift out of sync.

Clean it up with filters

On the mic source in the Audio Mixer (gear icon → Filters):

• Noise Suppression — pick RNNoise; it eats fan hum and room tone better than the basic option.
• Noise Gate — cuts the mic entirely when you're not talking. A close threshold around −30 to −25 dB is a sane start.
• Compressor — evens out quiet talk vs loud reactions.

Monitoring without the echo

In Advanced Audio Properties (mixer gear), monitoring for most sources should be Monitor Off. "Monitor and Output" plays your voice back at you — through speakers, that's an instant echo loop. If you monitor, headphones only, and never monitor a source into the same device you're also capturing as desktop audio.

The two audio gremlins (quick versions)

Echo / your voice twice: something is playing your mic back into itself — speakers on, monitoring set to Monitor-and-Output, the mic added twice (once global, once as a scene source), or your own stream open unmuted in a browser tab. Full hunt in the troubleshooting guide.

Voice drifting out of sync over a long stream: sample-rate mismatch, almost every time. Match everything to 48 kHz. Still off by a fixed amount? In OBS, Advanced Audio Properties → Sync Offset on the mic, adjusted in small steps (50–200 ms is typical), tested with a hand-clap on camera.

One honest gap: as of late 2026, Meld's public docs don't describe a per-track sync-offset dial like OBS has. If your voice drifts in Meld, match your mic to 48 kHz in system settings and re-add the track — and if it still drifts, that's a tell-us case, not a you-problem.

Why does my stream audio echo? Something is playing your mic back into itself: speakers instead of headphones, monitoring set to Monitor and Output, the mic added twice, or your own stream open unmuted in a browser tab. The full hunt is in the troubleshooting guide.

Why does my voice drift out of sync on a long stream? Sample-rate mismatch, almost every time. Set your mic and the app to 48 kHz — in system settings too — and the drift goes away.

How do I stop my mic picking up my fan and keyboard? In Meld, add the Voice Clarity filter to your mic track (start at Moderate). In OBS, use Noise Suppression (RNNoise) plus a Noise Gate on the mic source.

Should I monitor my own voice? Headphones only, and in OBS leave most sources on Monitor Off — "Monitor and Output" through speakers is an instant echo loop.
