Fortemedia’s Advanced Microphone Array Processing AMAP is a hybrid voice processing system that combines spatial filtering, source separation and adaptive statistical signal foretmedia to deliver advanced voice and audio capabilities to consumer electronic devices.
The second acoustic tube communicates with the second acoustic port and the fourth acoustic port.
ForteMedia — Listen and Sound Better. Anywhere!
Charge pump with a rapid-discharge path. The output capacitor is coupled between the output node and a ground. Company Company Always a voice processing technology innovator, Fortemedia provides leading edge solutions and technologies to enhance user experiences and promote speech communication efficiencies in challenging acoustic environments.
The first and second acoustic sensors are arranged in the first chamber and the second chamber, respectively. The first analog-to-digital converter converts the first analog audio signal to a first digital audio signal. The sound transmission device coupled to the first and second chambers includes third and fourth acoustic ports, a first acoustic tube, and a second acoustic tube.
The first acoustic tube communicates with the first acoustic port and the third acoustic port.
The method includes an acoustic conversion circuit converting an acoustic wave into an analog audio signal; an analog-to-digital converter ADC converting the analog audio signal into digital audio data; a first-level voice detection circuit detecting fortemediw activity in the analog audio signal; a second-level voice detection circuit detecting a beginning syllable of a key phrase in the digital audio data when the voice activity is detected in the digital audio data; and a third-level voice detection circuit detecting the key phrase from the digital audio data only when the beginning syllable of the key phrase is detected in the digital audio data.
In one embodiment, the sound processing device comprises a first microphone, a first analog-to-digital converter, a second microphone, and a second analog-to-digital converter.

AMAP can be easily deployed across a wide range of products with different microphone configurations. The delay buffer stores the processed data.
The two-piece computer has a first piece with a keyboard disposed thereon and a second piece with a display screen disposed thereon. The second analog-to-digital converter converts the second analog audio signal to a second digital audio signal, encodes a third digital audio signal according to the second digital audio signal, receives the first digital audio signal and a clock signal, outputs data bits of the third digital audio signal when the clock signal oscillates to a logic low level, and outputs data bits of the first digital audio signal when the clock signal oscillates to a logic high level.
The spatial filter generates processed data by using an internal adaptive control according to a control signal. The first acoustic extending structure is connected to the first acoustic opening. Each microphone receives an acoustic signal caused by a gesture performed on a surface of the microphone module and converts the received acoustic signal to a digital acoustic signal. Fortemesia processing element receives the trigger signal to execute a control process.
The invention provides a sound processing device.
