Junlin self-developed firmware algorithm is capable to complete the overall design from the front-end acoustic and electrical energy-exchanging components to the corresponding matching circuit, to solve the acoustic problems could be encountered from the most fundamental front-end.
The adaptive noise reduction algorithm can effectively suppress the noise without depending on the using environment.
The adaptive echo reduction algorithm can effectively cancel the echo noise coursed by the acoustic coupling of loudspeaker and microphone.
The reverberation cancellation algorithms were developed under different principles for various situations, and able to improve the voice intelligibility and the accuracy of voice recognition.
The microphone array design based on the beam forming can localize the voice source automatically.
Effectively suppress the interference source from non-target direction, and enhance the sound from target direction.
