Embodiment Construction

[0014] In order to make the above-mentioned features and advantages of the present invention more obvious and easy to understand, the following embodiments are given and described in detail with the accompanying drawings as follows.

[0015] When the Android system mobile electronic device using the MTK platform executes each software module related to audio signal processing, it can be found that the signal processing cycle between the hardware layer module and the interrupt layer module affects the load of the processor. In this way, the present invention sets the most appropriate signal processing cycle according to the acceptable load of the processor, and then limits the size of the buffer area of ​​each software module to shorten the processing time, so that the user can use the audio auxiliary function You can't feel the delay in audio signal processing, which increases the convenience of use.

Abstract

The invention discloses an audio signal processing method and device. The method comprises following steps of receiving a sound signal; processing the signal through executing functions of a hardware layer module, an interrupt layer module and multiple processing modules, thus playing the sound signal; according to the load capacity of the processing unit in an electronic device during the signal is processed, setting a signal processing period between the hardware layer module and the interrupt layer module; according to the signal processing period, setting the buffer size of the hardware layer module as the minimum reference size; and setting the buffer sizes of the interrupt layer module and the processing module to be less than or equal to the reference size.

Description

technical field [0001] The present invention relates to a data processing technology, and in particular, to an audio signal processing method and device. Background technique [0002] With the development of technology, almost all processors configured in today's consumer electronic devices have the function of processing sound effects for sound signals. In this regard, it is currently known that, for example, an application of integrating a sound assist function into a mobile electronic device (such as a smart phone) for the hearing impairment of the hearing-impaired person is available. This sound assist function can process the surrounding sound source received by the microphone built in the mobile electronic device or the headset, and synchronously play the processed sound through the output device such as the headset, earpiece or speaker. In this way, the user (the hearing impaired) can clearly hear the surrounding sounds, thereby improving the convenience of life. ...
