Online Mic Test
Test your microphone quality and get a Podcast Readiness Score — all in your browser. Analyze volume, background noise, and room echo in seconds. No audio leaves your device.
The Opportunity
Whether you’re recording a podcast, joining a Zoom call, filming a video, or sitting down for an interview — your audio quality matters more than you think. Background hum, room echo, or a gain level that’s too low can undermine your message before anyone hears a word. And by the time you notice it in playback, it’s too late to fix.
You shouldn’t need expensive audio analysis software or a sound engineer to know if your mic sounds good. That’s what this tool does — instantly, for free, right in your browser.
How It Works
Three steps. Thirty seconds. Know your mic is ready.
Select Your Microphone
Choose your recording device from the dropdown. The tool detects all connected microphones — USB, built-in, or audio interface — so you can test the exact setup you’ll be recording with.
Record a Quick Sample
Speak naturally for a few seconds. The tool captures your audio entirely in-browser — nothing is uploaded or stored. Your recording stays on your device.
Get Your Readiness Score
Instantly see your Podcast Readiness Score with a breakdown across volume level, background noise, and room characteristics. Green means you’re good to go; yellow or red tells you exactly what to fix.
Review & Adjust
Play back your recording with a real-time waveform display. Adjust your setup based on the recommendations, then test again until you’re in the green.
Why It Works
Professional audio analysis that runs entirely in your browser — no installs, no uploads, no cost.
Podcast Readiness Score
A clear, overall score that tells you whether your mic setup is podcast-ready. No guessing, no ambiguity — green means go, red means fix something first.
Volume & Gain Analysis
Real-time VU meter and peak level detection. See if your gain is too low (sounds distant) or too hot (clips and distorts) before you start recording.
Background Noise Detection
Identifies ambient noise that could ruin your recording — fans, HVAC, street noise, or electrical hum. Know your noise floor before you hit record.
Room Echo Assessment
Detects reverb and room reflections that make audio sound unprofessional. Get recommendations for positioning and acoustic treatment.
100% Private & Free
No audio is uploaded. No account required. No data collected. The entire analysis runs locally in your browser using the Web Audio API.
Works on Any Device
Desktop, laptop, or tablet — if it has a browser and a microphone, you can test it. Chrome, Firefox, Safari, and Edge all supported.
What Gets Generated
A complete audio quality report — everything you need to know before recording.
Podcast Readiness Score
An overall pass/fail score combining volume, noise, and room quality into a single, easy-to-understand rating with color-coded status.
Volume Level Metrics
Peak and average volume readings with a real-time VU meter. See exactly where your gain level sits relative to the optimal recording range.
Noise Floor Analysis
Background noise level measured in decibels with a rating. Identifies whether your recording environment is quiet enough for professional-quality audio.
Room Quality Assessment
Echo and reverb detection that evaluates your recording space. Includes practical recommendations for improving room acoustics.
Waveform Playback
Visual waveform display with playback controls. Listen back to your test recording and see the audio characteristics visually.
