## AI Voice Services

[ChatGPT Voice Mode Mic Test](https://capytoolkit.com/tools/audio/mic-test/chatgpt-voice-mic-test/): Test your microphone before ChatGPT Advanced Voice Mode sessions. Noise floor above −45 dBFS degrades interrupt detection. Check all five tests before you start.
[Claude Voice Mode Mic Test](https://capytoolkit.com/tools/audio/mic-test/claude-voice-mic-test/): Test your microphone before Claude Voice Mode sessions. Clipping causes transcript errors. Check noise floor below −50 dBFS before any voice conversation.
[Gemini Live Mic Test](https://capytoolkit.com/tools/audio/mic-test/gemini-live-mic-test/): Test your microphone before Google Gemini Live sessions. AGC helps but extreme noise floors still cause dropout. Confirm noise floor and latency before starting.
[Microsoft Copilot Voice Mic Test](https://capytoolkit.com/tools/audio/mic-test/copilot-voice-mic-test/): Test your microphone for Microsoft Copilot Voice. Windows audio enhancements affect every test result. Calibrate your OS gain staging here first.
[OpenAI Whisper Mic Test](https://capytoolkit.com/tools/audio/mic-test/whisper-mic-test/): Test your microphone before recording for Whisper transcription. Noise floor is the #1 accuracy variable. Check before any recording session.
[Amazon Alexa Mic Test](https://capytoolkit.com/tools/audio/mic-test/alexa-mic-test/): Test your microphone before using Alexa in a browser or app. Single-mic use requires lower noise floor than Echo device arrays. Check before setup.
[Apple Siri Mic Test](https://capytoolkit.com/tools/audio/mic-test/siri-mic-test/): Test your microphone before using Siri or macOS Dictation. On-device model sensitive to clipping. OS compressor masks but does not fix gain issues.

## Troubleshooting & Guides

[How to Run a Loopback Microphone Test](https://capytoolkit.com/tools/audio/mic-test/loopback-mic-test/): Run a loopback microphone test in your browser without extra software. Record and play back 3 seconds instantly to diagnose echo, distortion, and noise.
[How to Use Mic Playback to Diagnose Audio Quality](https://capytoolkit.com/tools/audio/mic-test/microphone-playback-test/): Use mic playback to diagnose audio quality problems before calls or recordings. Hear exactly what others hear, instantly, in your browser.
[How to Measure Your Room's Noise Floor](https://capytoolkit.com/tools/audio/mic-test/noise-floor-measurement/): Measure your room's noise floor in dBFS without any software. The Noise Floor Grade test takes 3 seconds and quantifies exactly how quiet your recording space is.
[Bluetooth Microphone Latency: What It Means and How to Measure It](https://capytoolkit.com/tools/audio/mic-test/bluetooth-microphone-latency/): Measure your Bluetooth microphone's round-trip latency with the Clap Latency Test. SBC adds 100–150ms; LC3 approaches wired performance. Know your baseline.
[Online Microphone Check: What to Test Before a Call or Session](https://capytoolkit.com/tools/audio/mic-test/online-microphone-check/): Complete microphone check in under 90 seconds using five browser-based tests. Noise floor, clipping, frequency response, echo loopback, and latency, all before your call.
[Microphone Not Working on Microsoft Teams](https://capytoolkit.com/tools/audio/mic-test/mic-not-working-teams/): Browser-based test isolates hardware from Teams settings. If the Noise Floor Grade works here, your mic is fine. The problem is in Teams' device selection or permissions.
[Microphone Not Working on Google Meet](https://capytoolkit.com/tools/audio/mic-test/mic-not-working-google-meet/): Browser test isolates hardware from Meet permissions. Chrome grants microphone access per domain, and meet.google.com may be blocked while other sites work fine.

[Microphone Not Working on Discord](https://capytoolkit.com/tools/audio/mic-test/mic-not-working-discord/): Discord voice activity detection fights a noisy floor. Browser test confirms hardware works, then adjust VAD sensitivity in Discord settings.
[Microphone Not Working on Android](https://capytoolkit.com/tools/audio/mic-test/mic-not-working-android/): Android microphone access requires both OS-level and Chrome-level permission. Browser test in Chrome confirms whether your mic is accessible to web apps.
[Laptop Microphone Not Working](https://capytoolkit.com/tools/audio/mic-test/mic-not-working-laptop/): Browser test distinguishes hardware failures from software problems instantly. Any Noise Floor Grade result means the hardware is working. Start here before changing settings.
[Microphone Not Working on Windows 11](https://capytoolkit.com/tools/audio/mic-test/mic-not-working-windows/): Windows 11 has three layered microphone privacy toggles, and all three must be On. Browser test confirms hardware and driver work before you check application settings.

## Microphone Tester Reference

[What Is Noise Floor?](https://capytoolkit.com/tools/audio/mic-test/reference/#what-is-noise-floor): Noise floor is the aggregate level of all unwanted background signals when no intended signal is active. Measured in dBFS. The Noise Floor Grade test quantifies it in 3 seconds.
[What Is Microphone Clipping?](https://capytoolkit.com/tools/audio/mic-test/reference/#what-is-microphone-clipping): Microphone clipping is permanent waveform distortion when audio exceeds 0 dBFS. The Clipping Detector flags it in real time. Understand the cause before adjusting gain.
[What Is Audio Latency?](https://capytoolkit.com/tools/audio/mic-test/reference/#what-is-audio-latency): Audio latency is the total delay from sound entering the microphone to system output. The Clap Latency Test measures the full browser round-trip in milliseconds.
[What Is Frequency Response in a Microphone?](https://capytoolkit.com/tools/audio/mic-test/reference/#what-is-frequency-response-microphone): Frequency response describes how a microphone captures sound across the audible range. The live Frequency Response display shows this in real time rather than as a static data sheet.
