This equipment is a multi-channel 48K high-definition USB recording equipment, which can be used for 4G / 5G network optimization testing, sound and vibration voiceprint data collection, panoramic sound collection, conference system microphone recording and other applications. We can provide customized services for customers. Over the years, we have established cooperative relations with many customers in the field of network optimization and industrial automation                                                      

                                                                 Four way USB recording MOS box

         The 4-way USB recording box is a device that can simultaneously record eight microphones or mobile phones. Each channel can be arbitrarily set to 8K / 16K / 48K speech sampling frequency, and supports 16bit linear speech format. The sampling frequency of 16K or 48K can be well applied to voiceprint recognition and speech recognition. Windows and linux drivers are provided. Users can call a few simple functions to realize recording. It is specially designed for speech recognition and voiceprint recognition of conference systems.
