关于AKM
音频模数转换器
音频芯片
AKM的音频模数转换器(ADC)采用自研的模拟与数字混合技术，不仅具备高集成度和设计自由度，而且有助于实现高清音频系统。
适用于各种音频系统，包括便携设备、高端音频设备和车载娱乐设备等。
除了旭化成微电子(AKM)的产品之外，世界上还存在有许多其他音频芯片。那么选择哪种芯片比较好呢？
我们认为，选择芯片不仅要参考产品手册上的规格指标，用起来放心也是一个重要考量因素。
在这里，我们就来介绍一下选择AKM音频芯片的理由。
舒适的在线会议
作为新的工作方式，在家办公和远程工作正在扩展。在家中参加在线会议的场景增多，与面对面的对话相比，系统能否保证清晰顺畅是许多人关注的重点，电话会议通讯质量不佳似乎使许多人感受到压力。
AKM的语音技术解决了电话会议中常见的语音问题，保证了沟通的顺畅。
真无线立体声耳机 (TWS)
近年来，真无线立体声耳机 (TWS: True Wireless Stereo) 的需求呈增长趋势。
要提高人们在聆听音乐、观看视频时的体验舒适度，以及在可穿戴设备中增加医疗辅助、互联网等多种功能，需要加强TWS机体的小型化设计、延长续航时间。
AKM为TWS应用提供合适的解决方案。
