Make a recording: Click "Record" to capture a sample, then play it back to check quality
Download if needed: Save your test recording for later reference or sharing

Understanding Your Microphone Properties

Channels: Shows if your mic is mono (1) or stereo (2). Most mics are mono, which is perfectly fine for voice
Sample Rate: Higher rates (like 48000 Hz) mean better quality. Standard is 44100 Hz or 48000 Hz
Sample Size: Bit depth of audio samples. 16-bit is standard, 24-bit is professional quality
Latency: Delay between speaking and processing. Lower is better - under 0.02s is great
Auto Gain: Automatically adjusts mic sensitivity. Useful but can sometimes cause issues
Echo Cancel: Reduces feedback and echo. Essential for video calls and streaming

What the Visual Indicators Mean

Volume Meter: Shows your current audio level. Green means good levels, yellow is getting loud, red means you're clipping (too loud).

Waveform Display: Shows the shape of your audio signal over time. Bigger waves mean louder sound. Look for clean, consistent patterns.

Frequency Spectrum: Displays which frequencies are present in your audio. Voice typically ranges from 80 Hz to 255 Hz for men, 165 Hz to 255 Hz for women.

Common Microphone Issues & Quick Fixes

Mic not detected? Check if it's properly plugged in. USB mics may need a moment to initialize
No sound at all? Make sure you've allowed browser access and the mic isn't muted in your system settings
Too quiet? Increase mic gain in system settings or move closer to the microphone
Too loud/distorted? Lower the gain or back away from the mic. Check if "boost" is enabled and turn it off
Echo or feedback? Use headphones, reduce speaker volume, or enable echo cancellation
Background noise? Enable noise suppression in your system settings or use a quieter environment

Tips for Better Audio Quality

Positioning matters: Keep your mic 6-12 inches from your mouth for best results
Avoid plosives: Speak slightly off-axis to prevent "popping" P and B sounds
Room acoustics: Soft furnishings reduce echo. Avoid empty rooms with hard surfaces
Use a pop filter: Even a simple foam cover can dramatically improve quality
Check your cables: Loose or damaged cables cause crackling and dropouts
Update drivers: Keep your audio drivers current for best performance

Different Microphone Types

Built-in laptop mics: Convenient but basic quality. Fine for casual calls
Headset mics: Good for gaming and calls. Consistent positioning helps quality
USB microphones: Great for podcasting and streaming. Plug-and-play convenience
XLR microphones: Professional quality but need an audio interface
Lavalier mics: Clip-on style, perfect for presentations and video
