Description

目前市面上最为出色的唱盘RPM转速和精度测试移动应用。
通过您之前从未体验过的实时图像的形式来查看您的唱盘的RPM速度的变化,以及抖晃动率。
测试您的唱盘的平均转速的方法有很多,部分唱盘甚至将此内置于其中,但是除了RPM之外,没有其他实用的方法可以准确显示抖晃动率随着时间的变化。平均转速可能看起来还不错,但是大幅抖晃将严重损害声音的表现,RPM将帮助您找到问题的所在并以可视化的形式为您显示其改善情况。
测试您的唱盘的转速和抖晃动率的精度,无论是16, 33 1/3, 45, 还是78。
如今有了世界级的RPM唱盘精度数据库,您可以研究其他RPM用户对他们自己的唱盘精度的发现和想法,还有最知名的IT专家所做的统计数据和模型
● RPM得到了世界最著名的唱盘制造商Rega Research Ltd的推荐。
● Youtube顶级科技视频博主Techmoan对RPM赞誉有加 ● 用于Stereophile杂志的高端TT评论
将您的全部rpm测试保存在“我的历史”中以备之后的查看和分享。
RPM使用您的iPhone的陀螺仪传感器来确定您的唱盘的转速,自动判定您所处的速度设置,并报告其精准度。
只需将您的iPhone放在您的唱盘上,靠近中心位置即可,无需放在中心轴上。在iPhone的旋转过程中,应用读盘将始终面向您的方位,数据的读取变得分外轻松。
RPM独一无二的功能在于它能够显示有关rpm精度变化情况的滚动图表,这会显示抖晃动效果,尤其是唱盘不平,发生磨损等情况。您甚至还可以检测由唱机唱针引起的小幅拖拽的情形。
您甚至可以在乙烯基唱片中心的周围实际绘制抖晃动率的变化情况,以此构建准确反映唱盘转速发生误差位置的热图。
对于升级程序,历史图形参数可自定义为: - 设置移动平均示例尺寸。 - rpm精度读盘设为绿色。 - 设置显示更新冻结之前的持续时间,以便在转动停止后可继续读取数据,这同时也需要将测试条目保存至“历史”并上传至世界TT数据库
- 检测并绘制16, 45, 和78记录。
校准模式在这里!(仅限升级程序) RPM的实时显示功能依赖于iPhone陀螺仪传感器的精确程度,当然,传感器通常都是非常准确的,如果您怀疑自己的传感器可能有问题,那么您现在可以使用校准模式来自动测试,然后在必要的时候实时应用校准。此自动校准使用指南针来计算唱盘的转数,如果您的iPhone是老款(iPhone 6S之前的版本)的话,那么结果可能不可靠,这时候如果您已经完成了独立的校准,那么仍然可以添加您自己的倍增器。广泛的测试意味着我们现在对于RPM的使用非常自信,它可以帮助您将唱盘的目标RPM设定在0.1%之内,前提是您的唱盘可以调整并且本身在该公差范围内稳定。
使用33 1/3 rpm进行自动校准,因为指南针在45和78 rpm档无法与相应转速匹配。请注意,通常是不需要校准的,而且只有未校准的测试项可上传至世界TT数据库,以确保所有的数据均具有可比性。
现在有了世界级RPM唱盘表现数据库,接受来自于世界范围的RPM用户的数据提交以最终构建可用于搜索精确度最高的唱盘的资源库。升级加入并上传您自己的TT数据,进入设置并确保您已经设置好了冻结时间,然后正常开始RPM测试即可。测试时间结束后,您可以给相关测试项命名,而后即可选择上传至世界数据库。当然,您也可以选择之后从“历史”中上传。

Very accurate.

Wasted Money

Douglas1001 on

United States

I liked the free version so much that I paid $14.99 for the upgrade. Big mistake. None of the pay to play functions actually work: freeze display, history, etc. What a waste of money.

Not accurate. At least on my iPhone 13 Pro

This app had me very confused. Had all of my tables running fast with extremely high wow and flutter. Now I know my quartz lock Technics SP-25 and my Pioneer PL-550 Run dead perfect. Used my prior app and it noted a perfect 33.33 for both of them. Tested my direct drive Luxman PD-277 and again, very close at 33.30. This would be my expected results. I’ll be deleting this app.

This is only a TRIAL VERSION!

After 10 tries you have to BUY IT. They don’t tell you that in the description. Had I known this I would never have downloaded it!

Utterly useless

History doesn’t record without paying $15, don’t waste your time.

10 failed tests and then they ask for money

Spoooon! on

United States

Every test failed with in a few seconds and then the app is locked until you pay. Plenty of other free apps to choose from.

Love the app but it won’t let me save any more

Wembely on

United States

Got a new turntable, and wanted to save it to my history and share it to the database. But for some reason, my app no longer allows me to save new turntable data. I deleted a bunch of the duplicates I had submitted thinking I might’ve reached my limit, but that’s not the case, because even with just a few measurements in my history, it no longer allows me to save new measurements. I’m sure it’s just a short term bug.

Obnoxious Paywall

United States

The app doesn’t for long enough to be useful before it interrupts and tries to get you to buy the app, over and over and over again. So obnoxious. Deleted.

Don’t

You’ve got only 10 “tests” then 15$ to upgrade.
