Everything here runs in your browser using the Web Audio API — no plugins, no installs. The channel test is the quickest way to figure out if a speaker has died or if one side is quieter than the other. The bass test lets you pick specific frequencies so you can hear exactly where your speakers start struggling. The sweep covers the whole audible range at once, which makes it easy to spot roll-off or weird resonances. The 3D mode uses HRTF filters that are designed to mimic how your ears naturally pick up sound from different directions — headphones give you the full effect. The noise generator is handy for shaking loose rattles or buzzing from a speaker grille, and pink noise in particular is what audio engineers use when setting up a room.
Six tests, one tool
ทดสอบช่อง
Play a tone through just the left, just the right, or both at once. The fastest way to spot a dead or imbalanced speaker.
ทดสอบเบส
Pick from 20 Hz up to 120 Hz and hear whether your speakers can actually reproduce it. Most budget speakers start dropping off around 80 Hz.
Frequency Sweep
การสแกนช้าๆ จาก 20 Hz ถึง 20 kHz คุณจะได้ยินว่าลำโพงเงียบลง บางลง หรือดังขึ้นที่จุดใด
เสียง 3D
ใช้ HRTF panning เพื่อให้เสียงรู้สึกเหมือนวนรอบศีรษะ ทำงานได้ดีที่สุดกับหูฟัง
Sound Pan
A tone that moves back and forth between left and right. Quick check for whether both channels are balanced and working.
สัญญาณรบกวน
White, pink, and brown noise. Good for testing full-range response and finding rattles. Pink noise is the go-to for speaker calibration.
