Earphone/Recording Test: LR
全新  This app is a comprehensive audio testing tool designed to help you easily and accurately evaluate the condition of any audio equipment, including earphones, headphones, speakers, and microphones. It’s intuitive enough for everyday users yet powerful enough for audio professionals. From LR channel checks and stereo imaging tests to frequency response, noise-based evaluation, and tone generation, all essential tools are provided in one place.

It is especially useful for users who want to quickly check for defects when purchasing new earphones, verify equipment before recording, or confirm speaker balance. It’s also highly recommended for podcasters, video creators, and music producers who rely on precise audio quality.

■ 1. LR Test (Left / Right Channel Test)

Checks whether the left and right audio channels are functioning correctly.

Clear voice prompts: “Left”, “Right”

Click tone / sweep tone modes

Detects cable faults, reversed wiring, or channel errors

Compatible with TWS earbuds, gaming headsets, and wired earphones

If you’re unsure whether your channels are swapped, this test gives an instant answer.

■ 2. Stereo Test (Stereo Image & Panning)

Evaluates the stereo field using sound that moves from left → center → right.

Fixed-speed and variable-speed panning

Smooth/step movement options

Tests space, separation, and panning accuracy

Very useful for home recording, movie audio tuning, or gaming setups.

■ 3. Frequency Test (Single-Frequency Tone Test)

Lets you listen to frequency responses directly.

20Hz to 20kHz tone playback

Low-frequency test (30Hz, 60Hz): diaphragm/woofer integrity

Midrange test (250Hz–1kHz): vocal clarity/distortion

High-frequency test (8kHz–10kHz+): tweeter performance, high-end distortion

Check for changes in volume, resonance, or rattling to diagnose issues.

■ 4. Balance Test (Balance Calibration)

Controls left/right volume balance with precision.

0% to 100% L/R adjustment

Live output changes

Useful for compensating personal hearing differences

If one side sounds louder, this tool helps you fix it.

■ 5. Channel Swap Test

Identifies and corrects reversed left/right output.

One-tap Left ↔ Right switching

Works with panning and tone tests

Detects device/app/cable-related inversion issues

Use when audio feels reversed during playback.

■ 6. Tone Generator & Sweep Test

Professional tool for generating custom tones.

Sine, Square, Saw options

Manual input: 20Hz–20kHz

Slow/Normal/Fast sweep modes

Amplitude control to detect distortion points

Useful for studio monitor checking and room tuning.

■ 7. Noise Tests (White, Pink, Brown, Fan, Rain)

Noise is an essential reference for analyzing audio characteristics.

White Noise: even energy → checks uniform output, hiss detection

Pink Noise: natural perception curve → best for tuning & balance

Brown Noise: low-frequency heavy → detects subwoofer rumble/boom

Fan / Rain Noise: real-world ambience → great for mic tests, ASMR, masking tests

White = “shhhh”, Pink = “ss-”, Brown = “buuu—” in character.

■ 8. Recording Test (Recording & Monitoring)

Evaluates microphone performance.

Play test tones → record immediately

Frequency spectrum analysis

Noise ratio and distortion detection

Supports external microphones

Highly useful for YouTubers, singers, and recording users.

■ 9. Live Analyzer

Professional visual tools for real-time monitoring.

Peak / RMS level meters

FFT spectrum analyzer

Separate L/R output graphs

Detects abnormal peaks or dips

Perfect for users who want measurable data.

■ 10. User Presets

Save frequently used combinations.

“Basic Check”

“Fast Earphone Test”

“Pre-Recording Check”

“Speaker Setup Test”

Create your own preset workflow.

■ 11. Test Log & Export

Store and export your test results.

Date, device name, test type

Save recordings

Export spectrum images

Generate CSV reports

Great for comparison or repair documentation.
