Signal is filtered, the processing such as gain adjustment, audio data is finally transmitted to the end PC or microprocessor makees echo cancellor, language
The operation such as sound identification, auditory localization.It is greater than four microphone arrays for number of microphone, generally requires CODEC grades multiple
Connection, audio stream generated in this way, is difficult to accomplish to meet the communication protocol of standard, so needing in microprocessor and audio
Increase a FPGA between CODEC to handle voice data stream, so that its agreement for meeting certain class standard.
Another kind of is to be selected the microprocessor with multiple digital audio input interfaces using digital microphone, directly will
The digital signal of microphone is transmitted to microprocessor.
Two kinds of common at present microphone array audio acquisition schemes all respectively have its disadvantage.Simulation wheat is used for the first kind
The scheme of gram wind, have to increase between microprocessor and audio CODEC in multi-microphone a FPGA be just able to achieve and
The communication of the two, and at present FPGA price it is generally relatively high, and the development difficulty of FPGA compare it is larger, need to pay compared with
High time, human cost.
Second class is the scheme using digital microphone, and digital microphone price first is more much higher than simulation microphone；
Secondly the sensitivity of digital microphone is not accomplished to simulate microphone so high, therefore unsuitable does far field microphone array；Most
Afterwards, few microprocessors more than four digital audio input interfaces currently on the market, even if having, price is also inevitable very high.
