Lario AI in one sentence
Lario AI is a real-time virtual microphone for macOS. It installs as a system audio device named "Lario Mic". You pick it as your input in any meeting app, and a native low-latency engine processes your voice on your Mac. Under 20 ms. Before it leaves for the call.
There is no plugin, no browser extension, and no cloud audio relay. The engine is written in Swift on top of Core Audio. Every dial. Adaptive gain, de-esser, envelope smoother. Is exposed, not hidden behind one magic slider.
How the real-time engine works
When you speak, audio enters the Lario AI engine in small chunks. The engine runs a chain of DSP stages. Voice activity detection, adaptive gain that holds your voiced loudness near a steady target, a de-esser that tames sibilance above 5.5 kHz, and an envelope smoother that lifts mid-sentence volume drops by up to 5 dB. The processed signal exits via Lario Mic, and the meeting app on the other side never knows the difference.
Live mode adds under 20 ms of latency. Studio mode runs a longer chain. Including stutter smoothing. And lands around 85 ms, better suited to prepared speaking than live banter. You pick the trade-off.
Who Lario AI is for
Lario AI was built for anyone whose live voice doesn't always match the idea behind it. Founders pitching investors, candidates in interviews, freelancers running client calls, podcasters who can't redo a take, and people who stutter or hesitate under pressure all use Lario AI for the same reason. The voice that reaches the other side is clearer, steadier, and easier to listen to.
It is not a deepfake. It does not change your voice into someone else's. It removes the rough edges from the voice you already have.
Lario AI vs noise filters and plugins
Most AI voice tools are either noise filters (Krisp, native Zoom AI) or post-call transcribers (Otter, Fireflies). Noise filters remove background noise. Transcribers run after the call ends. Lario AI is neither: it is a real-time stabilizer that shapes the voice itself, in the moment.
Because Lario AI runs on-device, your audio never leaves your Mac during live processing. Cloud-based competitors require streaming raw audio to a server, which adds latency and privacy concerns. Lario AI's native engine sidesteps both.
Pricing
Lario AI is free for three full sessions so you can evaluate the engine, the virtual mic, and the post-session AI insights in real meetings before paying. Pro is $6/month billed annually ($72/year), or $12/month billed monthly. Pro unlocks unlimited sessions, every preset, the full DSP chain, post-session AI insights, and priority access to new models.
Frequently asked
Is Lario AI the same as larioai or lario ai?
Yes. Lario AI is the brand. "larioai" is the domain (larioai.com) and "lario ai" is the spaced spelling. All three refer to the same product. A real-time virtual microphone for Mac.
Which platforms does Lario AI support?
Lario AI is a native macOS app for Apple Silicon and Intel Macs on macOS 13 or newer. A Windows build is on the roadmap.
Does Lario AI run on-device?
Yes. The real-time engine is fully native and runs on your Mac. Audio is never streamed to Lario AI servers for live processing. Optional post-session insights use the AI provider you pick (OpenAI, Anthropic, Google, OpenRouter) with your own API key. The app talks to the provider directly.
Is Lario AI free to try?
Yes. The free plan includes three full sessions with the real-time engine, the Lario Mic virtual device, and bring-your-own-key AI insights. No credit card required.
