Audio & Mikrofon — Tes & Alat

Uji mikrofon Anda langsung di browser — bicaralah dan lihat gelombang suara serta meter level dB bergerak secara langsung, periksa level puncak dan noise floor, lalu rekam klip singkat untuk mendengar persis apa yang ditangkap mikrofon Anda. Tidak ada yang diunggah.

Record your voice online — an in-browser dictaphone with pause and resume, a live waveform, and a player and download for every take. Everything stays on your device; nothing is uploaded.

Uji speaker, headphone, atau earbud Anda langsung di browser. Mainkan nada melalui saluran kiri, kanan, atau keduanya, sapukan lintas bidang stereo, dan ketahui dalam hitungan detik apakah salah satu saluran senyap.

Uji headphone atau speaker Anda di seluruh spektrum audio. Mainkan nada sinus murni dari 20 Hz hingga 20 kHz dengan slider, preset, dan sapuan penuh — dengar persis di mana perangkat Anda menurun, terdistorsi, atau menghilang.

Hasilkan nada stabil dari 20 Hz hingga 20 kHz. Pilih sinus, kotak, gergaji, atau segitiga, atur Hz tepat atau not musik, dan pan kiri atau kanan.

Free online metronome from 20 to 260 BPM. Set the tempo with a slider or tap it in, accent the first beat of the bar, and practice to a sample-accurate click with a beat indicator and measure counter.

Test your room acoustics with MATT-style gated tone bursts. Sweep a crisp Ta-Ta-Ta pattern through your speakers and mark the frequencies where the room blurs the bursts into a smear — the classic articulation test, right in the browser.

Play calibrated test tones in the browser. Step a 1 kHz sine through exact THD levels from 0.001% to 5% and find the distortion you can actually hear, or run a perceptual 20 Hz–20 kHz sweep that should sound evenly loud from end to end.

Uji seberapa dalam subwoofer, speaker, atau headphone Anda benar-benar mampu bermain. Mainkan nada sinus murni dari 20 hingga 200 Hz — ketuk preset, sesuaikan dengan slider, atau sapu seluruh rentang bass dan catat persis di mana nada rendah Anda berhenti.

Hear quantization, dithering, and noise shaping for yourself. A pulsing tone steps from 0 down to −90 dBFS, requantized live to 4–16 bits — plain, dithered, or noise-shaped — so you can find exactly where each version disappears.

Test your subwoofer with six synthesized kick drums stepping down from 70 to 20 Hz — each should get deeper, never louder — then sweep one channel from 200 to 40 Hz to find the frequency where bass stops being localizable and set your crossover below it.

Uji setiap speaker dalam setup stereo, 5.1, atau 7.1. Klik speaker pada peta ruangan untuk memutar nada hanya pada channel tersebut, jalankan sapuan otomatis ke semua channel, dan periksa subwoofer dengan sapuan bass 30–120 Hz.

Ukur level suara dengan mikrofon Anda, langsung di browser. Bacaan desibel langsung berupa perkiraan dB SPL atau dBFS yang akurat, statistik puncak, rata-rata, dan minimum, serta bagan referensi suara sehari-hari — tidak ada yang direkam atau diunggah.

Test your hearing range in the browser. A pure tone sweeps down from 22 kHz — tap the moment you hear it to find your upper limit, then a second sweep rises from 10 Hz for your low end, with an age-typical comparison for your result.

Uji headphone atau headset Anda di browser — mainkan nada melalui kanal kiri, kanan, atau keduanya, sapukan bidang stereo, periksa keseimbangan dan polaritas pengkabelan, dan uji diri Anda menebak telinga mana yang mendengar.

Test your stereo setup in the browser. Check the left and right channels and the phantom center, hear the level, timing, and head-shadow cues your brain uses to place a sound, and take a 10-round quiz on where a knock comes from.

Blind test your hearing with real statistics. Guess whether a mystery music clip is 16-bit or crushed to 8-bit, and whether a hi-hat lands in sync with the kick or milliseconds late — vote round by round and see if your score beats pure guessing.
