Mic Room Diagnostics — 3-Step Recording Quality Check

Mic & Practice Recording Check is a browser-based vocal practice setup checker built for home singers and podcasters. It runs four quick steps — background noise, space ring, and a voice setup check covering input level, plosive pop noise, and clipping — then gives you a readiness score and a prioritised list of improvements. All analysis runs locally in your browser; no audio is sent to any server.

Why your recordings sound bad even with a decent mic

Most practice recording problems — muddy tone, distant vocals, breath pops, or ugly distortion — come from setup and room behavior more than the mic itself. Bare walls create ring, HVAC adds hiss, and poor gain staging makes your voice either weak or clipped. This tool helps you catch those problems quickly so you can move the mic, change gain, or soften the room before you start singing.

What the four diagnostic steps measure

Step 1 captures a 5-second averaged noise floor and looks for likely low-frequency hum or broadband room noise. Step 2 listens to a single handclap and gives a quick estimate of how ringy the space feels for practice vocals. Step 3 checks whether your voice is coming in too quietly, whether consonants create strong low-end bursts, and whether loud lines clip. Step 4 combines everything into a practical readiness score and a short fix list.

How to use the results to improve your vocal recordings

A poor noise result points to a quieter room, less fan noise, or better cable routing. A ringy space check means you should add blankets, curtains, or move farther from bare walls. A low input result means you should move closer or raise gain slightly. Plosive warnings tell you to add a pop filter or angle the mic slightly off-axis. Clipping means your preamp gain is too high — pull it back and try again.

What this page is good at — and what it is not

This page is strong when you want a fast practical answer using the gear you already have: phone, laptop, USB mic, or interface mic. Its advantage is convenience and speed. Its limitation is that browser audio is not a calibrated measurement environment, so results should be treated as guidance for your current setup, not as lab-grade room acoustics data.

Tracking your recording environment over time

Every completed run is saved to the browser's local storage and shown in the history table on the start screen and in the report. Use it to compare scores before and after you move the mic, change rooms, add soft materials, or switch devices.

Mic & Practice Recording Check

A quick browser-based self-check for vocal practice recording. It helps you spot noise, space ring, gain issues, plosives, and clipping in under a minute.

All analysis runs locally in your browser. No audio is sent to any server.

Fast and convenient, but not a calibrated acoustic measurement. Use the results as practical guidance for your current device and room.

How to run the diagnostics

Allow microphone access when the browser asks, then follow the four steps in sequence. The page is designed to give a quick practical answer using your current device, not a professional acoustic report.

Step 1 — Background noise (5 seconds)

  • Stay completely silent. Don't speak, move, or touch the desk.
  • The tool averages RMS energy and looks for likely hum or broadband room noise patterns.
  • Pass threshold is −45 dBFS. Quieter is better for vocal recording.
  • If you fail, try turning off AC units, moving away from the PC, or tidying up your cable/power routing.

Step 2 — Space ring check

  • Press Start, then clap once loudly near the microphone.
  • The result is a quick browser estimate of how ringy the room feels for practice vocals.
  • Use it as a practical guide to compare rooms or mic positions, not as a calibrated acoustic reading.
  • If the space feels too live, try blankets, curtains, carpets, or a smaller softer area.

Step 3 — Voice setup check

  • Say "Pa Pi Pu Pe Po" loudly into the mic during the 5-second window.
  • The tool checks whether your voice is too quiet, whether low-frequency bursts suggest plosives, and whether loud syllables clip.
  • Clipping is flagged when any sample exceeds 0.98 full scale (−0.2 dBFS).
  • Fix low input by moving closer or raising gain slightly. Fix plosives with a pop filter. Fix clipping by reducing gain.

Reading the report

  • The overall score (0–100) estimates how ready your current setup is for practice recording.
  • The report highlights the next things to fix instead of pretending to be a lab-grade acoustic analysis.
  • Use-case bars show how usable the setup is for different recording goals.
  • The frequency snapshot is relative only and is not a calibrated frequency response graph.
  • Export the radar as PNG or the full report as a text file if you want to compare before and after changes.

Input device selection

  • Use the device picker in the Pitch Controls strip (mixer icon) to select a specific input device before starting the diagnostic.
  • The chosen device is stored in browser local storage and automatically used when you press Start.
  • If you have multiple interfaces connected, always confirm the correct one is selected to avoid measuring the wrong signal chain.

History and repeated measurements

  • Up to 10 previous runs are saved automatically and shown on the start screen and in the report.
  • Delete individual entries with the × button or clear everything with Clear All.
  • History is stored in browser local storage and is not shared across devices or browsers.
