Where do I start with ear training?如何开始听觉训练？
Open Train and start the next mission. Use Free Practice to pick a skill, sound and difficulty, or try the Daily Ear Workout.打开“训练”，开始下一个任务；也可在“自由练习”中选择技能、音色与难度，或进行每日听力训练。
How does simulated tuning work?模拟调音怎么练？
In Train → Free Practice, choose Unison by Ear or another live tuning exercise. Listen to the reference and your virtual string, turn the peg, then select Lock in. Review the error in cents and compare Your tuning with Perfect.进入“训练 → 自由练习”，选择“同度调音”等实操项目。聆听参考音和虚拟琴弦，转动弦轴后点击“确认音准”，查看音分偏差并对比“你的调音”和“准确”声音。
Do I need an instrument or microphone for training?训练需要乐器或麦克风吗？
Listening and simulated-tuning exercises use generated sounds. A real instrument and microphone access are needed only when using the live microphone tuner.听觉和模拟调音训练使用生成的声音。使用实时麦克风调音器为实物乐器调音时，才需要乐器与麦克风权限。
Why is the tuner not detecting sound?调音器为什么没有读数？
Allow microphone access in device Settings, select the correct instrument and tuning, and play one string in a quiet place. Adjust sensitivity in the app. The tuner intentionally ignores its own reference tone; use a real instrument or a tone from another device.在设备设置中允许麦克风权限，选择正确的乐器与调弦，在安静环境中演奏单根弦，可在 App 设置中调整灵敏度。调音器会忽略自身播放的参考音，请使用实物乐器或另一台设备发声。
