I do not know the USB audio device class before developing the driver for the USB audio device. I thought it was a hid driver and it should be easy to develop, later, I found myself in an unknown field. Thanks to the previous development of the mass storage firmware program and the knowledge of the ov511 USB camera driver, the development was completed even though it took more time and twists and turns in t

Introduction and comparison of common audio protocols for conference TV white PaperFirst, the digital audio principle: The sound is actually a kind of energy wave, therefore also has the frequency and the amplitude characteristic, the frequency corresponds to the time axis, the amplitude corresponds to the level axis. Usually the ear can be heard in the frequency of 20Hz to 20KHz of sound waves known as aud

SummaryThis article introduces the principle and basic implementation process of VoIP, and analyzes the composition of audio latency in the Ethernet environment. The experimental results show that the audio latency in the Ethernet environment is mainly composed of the buffer latency and API call latency, and the most important part is the API call latency. This paper proposes a method to reduce API call lat
