Vos Lite 是一款专业的移动声学测量工具，Vos 系列的轻量版，集声级测量、实时频谱分析与混响时间测量于一体。 【核心功能】 • 实时声级 SPL：大数字读数、Max 峰值统计、多种测量模式 • RTA 实时频谱：实时观察频率成分分布 • 声谱图：时间-频率-强度可视化，信号变化一目了然 • RT60 混响时间：脉冲法测量房间混响，专业评估声学特性 • Mag 频响测量：幅频/相位曲线，1/N 倍频程平滑 • 信号发生器：多波形输出，方便本机扫频测试 【特色】 • 横屏专业测量界面，为手机场景优化 • 支持导出测量报告 • 音频仅在设备本地处理，不录制、不上传 【适用场景】 室内声学检查、音响系统调试、噪音评估、声学教学与学习。 注：手机麦克风硬件因机型而异，测量结果供参考，可配合校准功能使用。

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.
