1
Your lowest comfortable note
Slide down on an "ah" until your voice starts to crackle, come back up one note, and hold it for a second.

2
Your highest comfortable note
Now go up. Stop where it still sounds like singing, not shouting or squeaking, and hold it.

Your range
Voice types overlap and teachers draw the lines differently. Where your voice feels easy matters as much as the extremes, so treat this as a starting point, not a label.
Note list
| Start | Note | Length | Off by |
|---|
Getting a reading you can trust
- Warm up first. Two minutes of humming and lip trills adds a note or two at both ends compared with singing cold.
- Comfortable, not extreme. The note you can only reach with a crack or a whisper is not part of the range you would sing a song in.
- Hold it for a second. A note only counts when it stays within ±60 cents for a full second, so a slide past a note is not recorded as your range.
- About an arm's length from the mic. Too close and loud notes clip; too far and the room echo blurs the pitch. Turn music and fans off.
Approximate voice type ranges
These are the ranges most choir directors use when they sort new singers. Trained singers often go several notes past them.
| Voice type | Typical range | Where it tends to sit |
|---|---|---|
| Bass | E2 – E4 | Low, dark; the bottom line of a choir |
| Baritone | G2 – G4 | The most common adult male voice |
| Tenor | C3 – C5 | Bright male voice; most pop lead lines |
| Alto | F3 – F5 | Lower female voice, warm middle |
| Mezzo-soprano | A3 – A5 | The most common adult female voice |
| Soprano | C4 – C6 | High female voice; carries the melody |
How the pitch model compares with YIN
Most free range testers use YIN or autocorrelation, fast formulas that look for repetition in the waveform. This page runs CREPE, a neural network trained on labelled pitch. We measured both on synthetic sung melodies where the true pitch is known:
| Recording | CREPE full | CREPE tiny | YIN | pYIN |
|---|---|---|---|---|
| Bass melody, clean | 8.1¢ · 0.3% | 8.3¢ · 1.4% | 13.3¢ · 4.2% | 13.1¢ · 4.4% |
| Bass melody, breathy (10 dB SNR) | 8.4¢ · 0.9% | 8.6¢ · 1.9% | 13.5¢ · 4.0% | 13.5¢ · 4.3% |
| Soprano melody, clean | 7.7¢ · 1.0% | 7.9¢ · 2.2% | 8.6¢ · 2.7% | 9.0¢ · 2.5% |
| Soprano melody, very breathy (3 dB SNR) | 9.4¢ · 33% | 8.6¢ · 7.2% | 40.9¢ · 44% | 15.6¢ · 70% |
| Soprano melody over piano chords | 8.3¢ · 25% | 11.0¢ · 28% | 13.9¢ · 16% | 13.0¢ · 14% |
Each cell: median error on the notes it did track · share of sung frames it got wrong by more than 50 cents or did not track at all.
What this means for you: on a clean or breathy solo voice, CREPE lands closer to the true note and avoids the octave jumps YIN makes on soft high notes. Over a piano it is not magic: it declines more frames instead of guessing, which is why the curve has gaps. For songs with a backing track, strip the accompaniment first.
Questions
会录下或上传我的声音吗？
不会。麦克风的声音从浏览器的音频引擎直接送进本标签页里运行的音高模型，每 100 毫秒一批 10 帧；内存里只留最近一秒的声音，之后只保留算出来的音高数字。不写硬盘、不发服务器——网络上只下载了页面和模型文件。拖进来的录音也是在内存里解码，同样不出这台设备。
准到什么程度？和别的音域测试有什么不同？
在我们 30 秒的 A2→A5 测试扫频上，tiny 模型的中位误差是 2.6 音分，full 模型 2.8 音分；平滑之后大约 2,800 帧里只有 1 帧落错八度。1 音分是半音的百分之一，一般人听不出 10 音分以内的差别。别的免费测试器大多用 YIN 或自相关，上面的对照表写清了神经网络在哪里更好（气声、高音），在哪里帮不上忙（有伴奏）。
放着伴奏或者合唱能测吗？
模型一次只跟一个音高。伴奏或别人的声音会拉低它的把握，这些片段在曲线下方显示为红条，而不是给出错音。要测一首带伴奏的歌，先用人声分离工具把伴奏去掉，再分析分离出来的人声。用麦克风测时请关掉音乐；想要参考音的话戴上耳机。
声部是怎么判断的？
用你唱稳的最低音和最高音去对照六个教科书区间（男低音 E2–E4、男中音 G2–G4、男高音 C3–C5、女低音 F3–F5、女中音 A3–A5、女高音 C4–C6）。每个声部按「覆盖了你多少音域」减去「你超出它多少」打分，低音那头权重更大，因为练声对低音的改变最小。它只是起点：声乐老师还会听你在哪一段最松弛、音色在哪里换声。
吉他、小提琴、笛子、口哨能测吗？
能，只要一次只响一个音：吉他单音、小提琴、长笛、小号、口哨、哼唱都能得到干净的曲线。模型覆盖约 32 Hz 到 1,975 Hz（C1 到 B6），很高的口哨和短笛可能超出上限。扫弦和弦、钢琴和弦不支持——模型会挑一个音或者给出低置信。
为什么第一次要下载 89 MB？没有 WebGPU 怎么办？
电脑上的新版 Chrome、Edge、Safari 有 WebGPU，录音会交给 89 MB 的 CREPE full 分析，每 30 秒音频约 3 秒；模型只下载一次，之后从浏览器缓存读取。实时麦克风表盘一直用 2 MB 的 CREPE tiny。没有 WebGPU 时全部走 CPU 和 tiny 模型，只用一条 WebAssembly 线程：每 30 秒音频约 18 秒，3 分钟的文件大约两分钟。
