IT之家 4 月 17 日消息,Android蓝牙通话即将迎来质的飞跃,超宽带语音技术将让你的声音更清晰、更真实。


目前,即使你使用最好的无线耳机,你的声音在传输到对方耳朵时也只能达到一般水平,如果你在开车时打电话,效果就更差了。虽然蓝牙技术在听音乐方面已经有了很大进步,但在通话质量方面却一直没有突破。不过,Android 系统可能会为车载设备带来更好的通话体验。


Android 专家 Mishaal Rahman 发现,Android 开源项目仓库中最近添加了一个补丁,实现了与蓝牙免提配置文件 v1.9 相关的功能。据IT之家了解,这个配置文件还处于草案阶段,它将扩展通过免提设备传输的频率范围,从目前的宽带语音(50Hz-7kHz)升级到超宽带语音(50Hz-14kHz),并使用相对较新的 LC3 编解码器来实现。但还没达到全带宽再现(20Hz-20kHz),这是大多数消费级蓝牙音频设备所能达到的水平。

可以说,这是蓝牙通话质量的一个巨大飞跃。当然,还需要硬件制造商跟进,但至少已经迈出了第一步。
