XVision vs Decibels Sound Level Meter

可编程的三维视觉艺术； 多组空间模型的串联和演绎，空间模型参数的配置，组合； 视角，镜头，平移，旋转，律动，自旋，元素色彩，无限种变换； 以上全部可编程。 在“幻视”中，我们可以添加一系列镜头，空间坐标。摄像机会自动依据设定的速度，平滑移动，或快速跳变到对应位置。于是，我们可以从任何角度观察三维模型。 而“幻视”不止这些，它把转子的旋转，排列，空间模型的形态，动作，全部交由用户自行编程。于是，你可以通过它创造自己专属的“宇宙”，你甚至可以手动绘制每一颗星星。 当所有镜头，平移，旋转，运动矩阵被组合起来，它们可以完成任意动作。而当空间模型被一幕一幕串联起来，它们就真正实现了一个流动的三维视觉宇宙。随着色彩的千变万化，转子的形态，律动，每一步细微的调节，都能产生令人惊叹的效果。

Sound Level Meter is an iOS tool for everyday environmental noise measurement—see levels in the field, keep a log, and share a polished Pro report when you need one. Features • Live A-weighted sound level with Fast / Slow time weighting • Session stats: energy-style average (LAeq) and peak (LAmax-style) • Acoustic calibration offset to align with a reference source • History with custom titles and optional location notes • Export CSV / JSON and Pro PDF measurement reports • Education: hearing & decibels, typical noise level ranges Good for Home and office background noise, street/neighbor logging, DIY checks around renovations or equipment, quick reference notes and sharing. Disclaimer Readings are estimated from the phone microphone and software. Results vary with device, mic sensitivity, handling, wind, reflections, and calibration. Outputs are for personal reference, logging, and sharing only—not legal metrology, certified lab reports, or compliance determinations. Use a calibrated standard sound level meter and qualified professionals when precision matters.
