Built-In Noise Suppression vs Dedicated Software: The Honest Comparison
The short answer: built-in suppression — free in Zoom, Teams, Meet and Webex — handles steady, mechanical noise well and is genuinely enough for most rooms. Dedicated software (Krisp, or NVIDIA Broadcast free on RTX hardware) wins in three specific situations: persistently loud environments, background voices, and cleaning what you hear, not just what you send. If none of those three describes your week, keep your money.

The comparison in one table
| Capability | Zoom | Teams | Meet | Webex | Dedicated (Krisp) |
|---|---|---|---|---|---|
| Steady noise (fans, hum, traffic) | Yes — 4 levels | Yes | Yes | Yes | Yes |
| Transients (typing, doors) | High level | Yes | Yes | Yes | Yes |
| Background voices | Voice isolation mode | Voice isolation (org-dependent) | No — voices kept | "All voices" mode is the opposite | Voice isolation |
| Cleans incoming audio | No | No | No | Phone calls only | Yes |
| Works across all apps | Zoom only | Teams only | Meet only | Webex only | Any app |
| Availability caveats | All accounts | Desktop app; policy-gated | Workspace-tier gated | Broad | Win/Mac; subscription |
| Cost | Free | Free | Free* | Free | $8–16/mo after trial |

What each app's built-in filter honestly does
Zoom — the most tunable
Four suppression levels under Microphone modes, from fidelity-preserving Low to strip-everything High, plus a voiceprint-based isolation mode for crowded rooms. Its weakness is its own musician mode silently disabling processing when enabled. For a solo worker willing to pick the right level, Zoom's built-in is the strongest of the four. Tuning guide.
Teams — solid but org-shaped
Real suppression, on by default, with a simplified toggle in the new client — but availability is mediated by your organisation: admin policies can pin it, the web client lacks it, and the aggressive level has hardware requirements. When it's on and supported, quality is genuinely good. Both clients' paths.
Google Meet — good, when you have it
Effective cancellation of non-speech noise with a visible indicator of what it's removing — but tier-gated, so many free personal accounts simply don't have the toggle, and Google is explicit that voices (including TV) pass through by design. Availability details.
Webex — capable, mode-dependent
Deep-learning noise removal as the default Smart Audio mode, an "all voices" conference-room mode, and uniquely, optional cleanup of incoming phone-call audio. The pitfall is mode confusion — music mode left on is the classic "Webex stopped filtering" report. Mode guide.
When built-in is enough — most of the time
This is the section a page with affiliate links is supposed to mumble, so here it is loudly. Built-in suppression at the right setting is the complete answer when:
- Your noise is steady and mechanical — fans, aircon, computer hum, distant traffic.
- Your noise is occasional — the odd door, a delivery, sporadic typing.
- You live in one meeting app, so per-app settings aren't a burden.
- You've already fixed placement — headset on, gain sane — per our fix hierarchy.
That describes the majority of home offices. Tune the free filter first; spend money only on what it demonstrably fails to catch.
When dedicated software earns its subscription
- Persistently loud environments — street-facing windows, construction seasons, kids at home: noise that's unpredictable, frequent and loud is where separate models with more compute visibly outperform.
- Background voices — the built-in filters' structural blind spot (they protect speech). Voice-isolation modes exist in Zoom and Teams, but they're account- and device-dependent; a system-level tool brings it everywhere, including Meet.
- Incoming noise — when the problem is what you hear from noisy callers all day (support roles, recruiting, sales), only the system-level layer addresses it across apps.
- Many apps, one setting — consultants living in four different clients get one filter that travels, instead of four settings screens with different names.
- RTX owners: try free first — NVIDIA Broadcast occupies the same architectural spot at no cost; if it clears your noise, done.
Test the paid layer against your tuned settings
The decision is empirical, and the experiment is free: tune your app's built-in filter with our guides, then run Krisp's 7-day trial (no card) on the same calls and let colleagues judge the difference. Keep whichever wins.

Is built-in suppression good enough for most people?
Yes — for typical home offices with steady or occasional noise, the free filters at the right setting are the whole answer. The paid layer is for persistently loud environments, background voices, and incoming-audio cleanup.
Can I run built-in suppression and Krisp together?
Pick one. Two filters processing the same stream double the artifacts, not the cleaning. If you adopt a system-level tool, drop the in-app setting to low/off and let one layer work.
What about NVIDIA Broadcast?
Free system-level noise removal for RTX GPU owners — the same architectural position as Krisp for the core use case, minus the meeting-AI extras. If you have the hardware, it's the obvious first experiment.
