低延迟手指鼓Low-latency finger drum

指尖落下，声音即刻响起 Tap down, sound right back

八个鼓垫、实时循环录制、麦克风采样与可导入音色——一台装进口袋的鼓机。为快速连击与即兴演奏而生。 Eight pads, live loop recording, microphone sampling and importable tones — a drum machine in your pocket, built for fast hits and improvisation.

核心功能Core features

为演奏而设计的每一处细节Every detail tuned for play

从落指出声到循环叠层,手指鼓把鼓机的核心动作做到顺手、即时、可玩。From the first tap to layered loops, Finger Drum makes the core moves of a drum machine instant and playable.

落指即响Tap to sound

手指一落就出声,不等抬起。32 voice 复音池让多指同时按下、快速连击也不丢音。Sound fires the moment your finger lands — not on release. A 32-voice pool means rapid rolls and multi-finger hits never drop a note.

循环录制 · 叠层Loop & overdub

一键开始循环,每次开启录音就叠一层。播放头实时走动,任意一层都能单独撤销或一键清空。Start a loop, then stack a layer each time you record. A live playhead runs the loop, and any layer can be undone or cleared on its own.

麦克风采样Sample anything

对着麦克风录一段(最多 5 秒),立刻变成某个鼓垫的音色。人声、桌面敲击、任何声音都能成鼓。Record up to 5 seconds through the mic and it instantly becomes a pad. Your voice, a tap on the desk — anything can be a drum.

音色与导入Tones & import

内置 Tones Low / High 两套不同音高的音色包;长按鼓垫即可导入自己的 WAV / MP3 / FLAC 装载到任意垫。Built-in Tones Low / High packs at different pitches, plus long-press any pad to load your own WAV / MP3 / FLAC.

为延迟而生的
音频引擎An audio engine
built around latency

从落指到出声只走一条最短路径:Dart 调用 FFI 进入 C 核心,由 miniaudio 在 256 帧、约 5 毫秒的缓冲下输出。界面层不会在触发路径里加入任何额外的异步阻塞。From finger to sound there's one shortest path: Dart calls into a C core over FFI, and miniaudio outputs at a 256-frame, ~5ms buffer. The UI never adds async blocking to the trigger path.

创作者怎么说What creators say

手感是第一位的Feel comes first

"延迟低到几乎感觉不到。在地铁上随手就能搭一段 beat,叠层撤销特别顺。""Latency you basically can't feel. I build beats on the train and the layer-undo flow is so smooth."

L林 · 独立音乐人Lin · Indie musician用了 6 个月6 months in

"麦克风采样太好玩了。把儿子的笑声做成鼓垫,一首歌就这么起来了。""Mic sampling is a blast. I turned my kid's laugh into a pad and a whole track grew out of it."

陈陈 · 编曲师Chen · ProducerApp Store 评价App Store review

"界面克制、没有花哨动画,但每一下反馈都很扎实。当成随身鼓机非常合格。""The UI is restrained, no flashy animation, but every hit feels solid. A proper pocket drum machine."

FAQ

常见问题Common questions

App 免费下载,核心打鼓、循环录制与内置音色包均可使用。部分进阶内容通过应用内购买解锁。The app is free to download — core drumming, loop recording and the built-in tone packs are all included. Some advanced content unlocks via in-app purchases.

不会。麦克风采样完全在设备本地处理,音频不会上传到任何服务器。详见隐私协议。No. Microphone sampling is processed entirely on your device; audio is never uploaded to any server. See the Privacy Policy for details.

可以。长按任意鼓垫,选择 WAV / MP3 / FLAC 文件即可装载到该垫。Yes. Long-press any pad and pick a WAV / MP3 / FLAC file to load it onto that pad.

手指鼓支持 iOS 与 Android 手机及平板,横屏体验为平板优化。Finger Drum runs on iOS and Android phones and tablets, with a landscape layout tuned for tablets.

音频走 Dart → FFI → C 核心 → miniaudio 的最短路径,256 帧约 5ms 缓冲,实际延迟受设备影响。Audio takes the shortest path — Dart → FFI → C core → miniaudio — at a 256-frame, ~5ms buffer. Real-world latency depends on your device.
