Audio signal processing system of reading kiosk

Abstract

The embodiment of the invention discloses an audio signal processing system of a reading kiosk. According to the technical scheme, the DSP processor is in butt joint with the microphone input circuitand the background sound input circuit and receives the reading sound signal and the background sound signal, echo cancellation processing is conducted on the reading sound signal through the echo processing circuit in advance, and therefore interference of echoes on reading recording is avoided. And the DSP processor performs sound mixing and digital audio processing on the reading sound signal and the background sound signal to obtain a corresponding sound mixing audio and outputs the sound mixing audio. When a user uses the reading kiosk to read, the user can hear the reading sound and playthe reading sound along with the background music, monotony of human voice record playing is avoided, the reading record is more beautiful, and therefore the reading experience of the user is optimized. Besides, digital audio processing is performed on the reading sound signal independently through the DSP processor so that the corresponding original sound audio can be obtained, and thus the useris enabled to acquire the clear and clean original sound reading record.

Description

technical field [0001] The embodiment of the present application relates to the technical field of audio processing, and in particular to an audio signal processing system of a reading booth. Background technique [0002] With the continuous development of society, people's spiritual needs are also increasing. In order to improve the quality of life of urban residents and enrich people's spiritual needs, reading booths will be set up in various areas of the city. Reading booths generally have the functions of reading aloud, practicing, and speech training, which can guide people to participate in reading, let people calm down, return to their hearts, and express their hearts freely. [0003] At present, most reading booths are set up as immersive soundproof spaces. The reading booths are equipped with recording and playback devices. During the process of users reading aloud, the recording equipment records the user's voice and plays it through the speaker. Users can read a...

Problems solved by technology

[0004] However, when the existing reading kiosks are in use, the reading recordings generated by them are susceptible to noise interference such as echoes, and the reading recordings are relatively monotonous, resulting in relatively poor reading experience for users.
