分贝仪 vs Live Spectrum Analyzer

— 主要功能 — 【实时分贝测量】 打开即测，实时显示当前分贝，并同步呈现最低、平均、最高值，直观掌握声音变化。 【多样仪表盘】 提供多款风格各异的分贝仪表盘，指针与刻度随声音灵动变化，左右滑动即可切换喜欢的样式。 【噪音等级提示】 根据当前分贝自动标注“极静 / 安静 / 一般 / 吵闹 / 很吵 / 极吵”等级，并以颜色区分，一眼看懂环境是否舒适。 【测量记录与图谱】 一键保存测量记录，自动生成整段测量的分贝变化曲线图谱，并记录时间、时长、位置、设备机型等信息，方便日后回看对比。 【录像叠加分贝】 录制视频时，画面上实时叠加当前、最大、最小、平均分贝与录制时长，视频保存到相册与 App 内，声音数据一目了然。 【拍照标注分贝】 拍照时自动标注当下的分贝与时间，照片同步保存到相册与 App 内，为每张照片留下声音印记。 【位置与设备信息】 在你授权定位后，可为记录附上位置名称与地址，并自动识别设备机型，让每条记录信息更完整。 【深色模式与自定义图标】 支持浅色 / 深色 / 跟随系统主题，界面清爽护眼，并可切换多款 App 图标。 — 适用场景 — • 居家生活：检测睡眠、休息环境是否安静 • 办公学习：了解办公室、图书馆、教室的噪音水平 • 户外出行：记录街道、地铁、商场、餐厅等场所的声音环境 • 装修施工：评估电器、机械设备运行时的噪声大小 • 亲子育儿：关注婴幼儿所处环境的音量，营造安静空间 — 适合人群 — • 关注居住与办公环境舒适度的用户 • 需要随手记录、对比声音环境的人群 • 对声音、噪音、音量感兴趣的爱好者 • 希望在照片、视频中记录现场分贝的创作者 说明：本 App 的分贝数值基于设备麦克风智能估算，受设备硬件差异影响，结果仅供参考，不作为专业计量或法律依据。 说明：部分高级功能（如查看全部测量记录、多种仪表盘样式、录制视频分贝检测、拍照分贝检测等）需通过一次性内购解锁，内购为永久买断制，无订阅费用。

Live Spectrum Analyzer is a real-time audio visualization tool for musicians, students, teachers, sound makers, and anyone who wants to see sound clearly. Use the microphone for live input, or import an audio file from Files to inspect how frequency, amplitude, pitch, and dynamics change over time. Switch between waveform, FFT, sonogram, spectrum bars, VU meter, pitch, octave bands, peak hold, envelope, waterfall, phase, Lissajous, and XY Scope views. Each mode is designed for quick visual reading while you listen, tune, practice, demonstrate acoustics, compare sounds, or check a recording. The app also provides practical analysis readouts, including RMS, peak level, decibels, detected pitch, strongest frequency peaks, spectral centroid, zero crossing rate, dynamic range, estimated BPM, beat strength, mel bands, chroma, noise floor, and clipping status. Results are intended as helpful visual references rather than certified measurement data. Key features: • Live microphone waveform and spectrum visualization • Import audio files for playback and local visual analysis • Waveform, FFT, sonogram, bars, VU, pitch, waterfall, phase, and scope modes • Adjustable gain, time window, FFT floor, sonogram brightness, contrast, and speed • Pitch reference, tolerance, microphone gain, and noise gate settings • Record audio locally, review saved recordings, and share or delete files • Capture visualization snapshots as PNG images • Local-first workflow with no account required Subscription and purchase information: The app offers a free experience and optional Pro access. Actual prices, trials, promotions, and availability are shown in the App Store. Privacy and data information: Your microphone input, imported audio, recordings, snapshots, and analysis results stay on your device by default. The app does not require an account and does not upload your media to a server operated by us.
