对照上代 AirPods Pro有个没有显著的革新是提早下降

The wireless earphone of malic company tastes AirPods Pro newly to already was rolled out far two months, civilian net still needs 2 months to just receive money now. The AirPods before be likened to, everybody can see " Pro " the remarkable innovation of edition is to fall automatically a confusion of voices, but honest, before its in advance also is compared little. Si Difen of employee of open up of musician battle hardware - division Yi I (Stephen Coyle) a only guest article discussed that one side. What demand pays attention to is, in advance is broadcasted to normal video will tell was not a title (probably user impressions is remarkable without that end) . Impressions is remarkable is an user the noise that call in, probably the acoustics in game. Consequently I use division Yi situation of two individual type goes textual research that, the clavier that at first is IOS clavier endures word noise, it can be everybody most in the center of often come up against in advance title. The second be division Yi my open up a game that the name is TAPT. The play that writes as a result of him has the demand of high frequency in advance. Of clavier of his game fight IOS

苹果公司的无线耳机新品AirPods Pro已经推出近两个月,目前官网仍需1个月才发货。相比之前的AirPods,人们能看到“Pro”版的明显改进是主动降噪,但其实,它的延迟也比之前少了。音乐家和软件开发人员斯蒂芬-科伊尔(Stephen Coyle)的一篇博客文章探讨了这一点。

需要注意的是,延迟对一般的视频播放来说不是问题(或者用户感受不那么明显)。感受明显的是用户发出的声音、或者游戏中的音效等。

因此科伊尔用两个方式来验证这点,首先是iOS键盘的键盘打字声音,它可能是人们最常遇到延迟问题的地方。第二是科伊尔开发的一个名为TAPT的游戏。因为他写的游戏有低音频延迟的需要。

他的游戏和iOS键盘的不同之处在于前者启动并持续保持“音频会话”,而后者则没有。通过TAPT和系统键盘,科伊尔发出一系列测试声音: 每次设备和他自己的App的连接,都会连续触发10个声音,使用设置为90 bpm的节拍器来保持一致。而对于键盘,他放弃了第一个节拍,对这19项测量值进行平均值,得到延迟的数字。

结果如何?第一代AirPods使用苹果的W1芯片,测量274毫秒的延迟。今年早些时候发布的第二代AirPods采用了苹果新的H1芯片,将延迟降低到178毫秒。

但使用同一款H1芯片的AirPods Pro的性能更好,达到了144毫秒。 科伊尔承认,从第一代AirPods到AirPods Pro,减少了130毫秒的改进在数据看起来并不是很多,但它会让AirPods Pro相当接近无缝连接。

另一个值得注意的是第二代AirPods和AirPods Pro之间的改进,尽管它们使用相同的H1芯片。但后者意味着苹果已经找到了用同样的芯片来减少延迟的方法。
