Pickup Apparatus and Pickup Method

摘要

A pickup apparatus includes a digital signal processor, at least one microphone, multiple amplifiers, and multiple analog-to-digital converters (ADCs), where each microphone is configured to receive an audio signal, and send the audio signal to an amplifier corresponding to the microphone, each amplifier is configured to amplify the received audio signal, and send the amplified audio signal to an analog-to-digital converter corresponding to the amplifier, each analog-to-digital converter is configured to convert the received audio signal into a digital signal, and send the digital signal to the digital signal processor, and the digital signal processor is configured to receive multiple digital signals sent by the multiple analog-to-digital converters, determine an unclipped digital signal from the multiple received digital signals, and determine an output signal according to a gain value corresponding to the unclipped digital signal. The pickup apparatus disclosed in the present disclosure may have excellent pickup performance in various pickup scenarios.

1. A pickup apparatus, comprising:
a digital signal processor; at least one microphone; multiple amplifiers; and multiple analog-to-digital converters, wherein the multiple amplifiers are in a one-to-one correspondence with the multiple analog-to-digital converters, wherein each amplifier in the multiple amplifiers corresponds to one microphone in the at least one microphone, wherein at least two amplifiers of the multiple amplifiers that have different gain values from each other correspond to a same microphone in the at least one microphone, wherein the microphone is configured to:
receive an audio signal; andsend the audio signal to an amplifier of the multiple amplifiers corresponding to each microphone, wherein each of the multiple amplifiers is configured to:
amplify the received audio signal to obtain the amplified audio signal; andsend the amplified audio signal to an analog-to-digital converter of the multiple analog to digital converters corresponding to each amplifier, wherein each of the multiple analog-to-digital converters is configured to:
convert the received audio signal into a digital signal; andsend the digital signal to the digital signal processor, and wherein the digital signal processor is configured to: receive multiple digital signals sent by the multiple analog-to-digital converters, determine an unclipped digital signal from the multiple received digital signals; and determine an output signal according to a gain value corresponding to the unclipped digital signal.
