Qualcomm announced that it was planning a special event on March 19th. And although there is practically no information on the subject of the event, it is possible to make assumptions based on the published image.
Judging by the picture, the event will be related to the sound. Probably Qualcomm will be hosting a presentation of a new audio chipset or audio technology. About a year ago, the company announced the QCC3026 sound-to-chip system, focusing on using the initial and mid-range Bluetooth handsets.
It is possible that a new audio chipset will be released next Tuesday, improving the quality of wireless sound.
