常见问题
这些声音是真实录音还是合成的？Are these real recordings or synthesized?
209 个素材中，真实录音来自 Pixabay 与 Mixkit 两大免版权可商用音源（雨声、海浪、车流、鸟鸣、篝火等），经响度归一与无缝循环处理后由浏览器本地混音；双耳节拍、萨索尔吉频率、彩色噪音与宇宙氛围为本站原创合成，同样免费可商用。Field recordings come from Pixabay and Mixkit (royalty-free), loudness-matched and seamlessly looped, then mixed locally in your browser; the binaural beats, solfeggio frequencies, colored noise and space ambience are original CC0 syntheses by 365Lab.
收费吗？需要注册吗？Is it free? Do I need an account?
完全免费，无需注册。你的混音、组合和语言偏好只保存在本机 localStorage，不会上传到任何服务器；页面会展示 Google 广告，并用百度统计记录匿名访问量。Completely free, no account. Your mix, presets and language stay in your browser's localStorage — nothing is uploaded. The pages show Google ads and count anonymous visits with Baidu Analytics.
导出的音频可以商用吗？Can I use exported audio commercially?
录音素材基于 Pixabay Content License 或 Mixkit 免版税许可，均可免费商用；原创合成波形以 CC0 发布。逐条署名信息见「素材来源」。导出功能在浏览器本地渲染，不经过服务器。Recordings are under the Pixabay Content License or the Mixkit Free Sound License; original tones are CC0 — all free for commercial use. Full attribution is listed under “Credits”. Export renders locally in your browser.
手机上也能用吗？会费流量吗？Does it work on phones? Is it data-heavy?
支持。每段录音约 60 秒 / 1MB 左右，只有点开的音色才会下载，之后有 Service Worker 缓存，重复收听几乎不耗流量。移动端为竖屏单列混音台，可加入主屏幕当 App 使用。Yes. Each clip is about 60s / ~1MB and only downloads when you add it; the service worker caches it afterwards. Add it to your home screen as an app.
睡眠定时器到点后会怎样？What happens when the sleep timer ends?
最后 30 秒平滑淡出后自动停止，不会突然静音惊醒你；组合与音轨设置会保留，下次打开继续。到点后提示里还能一键「再睡 5 分钟」。The mix fades out smoothly over the last 30 seconds, so you won't be jolted awake. Your tracks are kept for the next visit — and the finish toast offers a one-tap “Snooze 5 min”.
