WM8861 and WM8862 are two HD music devices announced by Wolfson Micro electronics. These high definition devices are aimed at laptop and PC users and are claimed to provide up to 5 times greater audio quality than anything presently available thanks to 2Vrms cap less output and 105db DAC signal-to-nose ratio.
The WM8862 and WM8861 come with Wolfson’s Clarity Audio Studio software that helps the battery life of a laptop to be extended by up to half an hour with their innovative power management qualities.
These Wolfson devices bring about a 45% reduction in the space requirements of the PCB board, while there is a 56% reduction in the audio PCB BOM in a laptop. There are not many external devices needed to increase audio quality with the WM8862 and WM8861. There is also 100% seamless support offered for a headphone.
There are many high-tech features employed in these Wolfson devices that bring about such sound quality. One of these is the Wolfson SilentSwitch feature that ensures the audio performs to its maximum even while powering through unused paths. There are no clicks or pops heard.
The hardware features Dynamic Range Controllers and there is also a massive improvement in the speaker frequency. This results in a great sound from those relatively tiny speakers without causing any audio signal processing burden to the host processor.
The result is a HiFi audio from your humble laptop. The sound is something DJs, musicians, producers and even casual music lovers will absolutely enjoy.
Consumers are offered a choice of various kinds of headsets to be used with these Wolfson HD music devices. There is an advanced and efficient headset detection feature in both the Wolfson HD devices that actively checks when the user connects the headset.
The detection feature immediately finds out the connection used by the headset and changes the devices’ input connection in order to match the headset for effective performance. This is quite a useful feature especially since there are so many headphone connectors and headsets available today, and users don’t always pay attention to the type of connection of the headset when they buy it.
Wolfson WM8861 has and additional Master I2S audio as well as I2C/SPI control interface for effectively controlling downstream audio devices such as the Wolfson WM0010 DSP, other audio DSPs and digital input amplifiers and DACs. This offloads the audio signal processing resulting in longer battery life and lower consumption of power.
Wolfson WM8861 as well as WM8862 will only be offered for sampling in December and the prices haven’t yet been released. But these HD music devices are expected to become popular.
