为演奏响应而设计的 原生音频核心A native audio core designed for responsive play
pad 在落指时触发，Dart 通过 FFI 调用 C 音频核心，再由 miniaudio 输出。App 会向系统请求低延迟配置，但实际端到端延迟取决于设备、系统、音频路由与当前负载，因此不宣传固定毫秒数。Pads trigger on finger-down; Dart calls a C audio core over FFI, then miniaudio outputs the sound. The App requests a low-latency configuration, but end-to-end latency depends on device, OS, audio route, and current load, so we do not claim a fixed millisecond figure.

FAQ
常见问题Common questions
不会。当前提供 8 条一小节节奏、左右手/手指提示、播放高亮和可调 BPM，没有击打准确度、评分、课程进度或连续打卡。No. The current feature has eight one-bar rhythms, left/right-hand and finger cues, playback highlighting, and adjustable BPM. It does not measure hit accuracy, score playing, track course progress, or maintain streaks.
麦克风采样不会触发 FingerDrum 的 AI 后端上传；但在 iOS 上，自定义采样可写入你的 iCloud Documents 并由 Apple 同步。详见隐私协议。Microphone sampling does not trigger an upload to FingerDrum's AI backend. On iOS, however, custom samples may be written to your iCloud Documents and synced by Apple. See the Privacy Policy.
可以。歌曲导入支持 MP3、M4A、AAC、WAV、AIFF、CAF 与 FLAC；pad 音色可导入 WAV、MP3 或 FLAC。普通导入不会自动启动 AI 上传。Yes. Song import supports MP3, M4A, AAC, WAV, AIFF, CAF, and FLAC; pad sounds accept WAV, MP3, or FLAC. Ordinary import does not automatically start AI upload.
FingerDrum 面向 iOS 与 Android 手机及平板实现，界面锁定横屏并针对平板演奏优化。公开商店可用性以正式商店页面为准。FingerDrum is implemented for iOS and Android phones and tablets, with a landscape-only interface tuned for tablet playing. Public availability is shown only on official store listings.
pad 在落指时触发，音频走 Dart → FFI → C 核心 → miniaudio。App 请求低延迟配置，但实际延迟随设备和音频路由变化，因此不承诺固定毫秒数。Pads trigger on finger-down and audio flows through Dart → FFI → a C core → miniaudio. The App requests low-latency settings, but actual latency varies by device and audio route, so no fixed millisecond figure is promised.
