Pocket Music Room
随身琴房

A piano, a mechanical-style metronome, and a live pitch chart. Open it and play.

打开就能弹。把钢琴、机械风格节拍器和实时音高走纸，放进随身的小琴房。

Getting started

Piano: play the keys at the bottom. Slide the brass range handle to explore C3–C6; double-tap it to return to middle C. The Sustain lever holds notes.
Metronome: drag the pendulum weight vertically to change speed, or use +/−. Tap Start to run, TAP to set a tempo, and the time signature to choose a meter. The metronome can continue while the phone is locked.
Pitch: swipe the wooden panel sideways or tap its navigation arrow. Tap the round listening light and allow microphone access. Sing or play one note at a time. The six-second chart follows pitch; the green indication means you have stayed within ±5 cents for one second. Tap the reference pitch to change A4.

Troubleshooting

No sound? Raise the media volume and check whether audio is routed to Bluetooth headphones. Microphone unavailable? Enable microphone permission in Settings → Apps → Pocket Music Room → Microphone. A quiet room and a single voice or instrument give the clearest pitch readings; polyphonic chords are not supported by the pitch detector.

使用帮助

钢琴：直接弹底部琴键。拖动黄铜音区滑钮浏览 C3–C6，双击滑钮回中央 C；打开延音拨杆可以保留松手后的声音。
节拍器：上下拖动摆锤或点 +/− 调速，点开始运行，TAP 跟着你的拍击设定速度；点拍号更换节拍。锁屏后节拍器可以继续运行。
音高识别：左右滑动木面板或点底部箭头翻面。点圆形聆听灯并允许麦克风访问，唱或演奏单音。纸带显示最近六秒的音高轨迹；偏差在 ±5 音分内保持一秒，读数牌会变绿。点参考音高可以修改 A4。

常见问题

没有声音时，请提高媒体音量并检查蓝牙输出设备。麦克风无法使用时，请在“设置 → App → 随身琴房 → 麦克风”允许访问。音高识别适合较安静环境中的单个人声或单音乐器，不适合同时识别多个和弦音。
