Sound-effect processing equipment and method

Abstract

The invention discloses a sound processing device, comprising an audio signal receiving unit used to receive audio signals exported from a portable audio device, an audio processing unit used to process the received audio signals, a volume adjusting unit used to regulate the volume of the processed audio signals according to the changes of the volume of the environmental sounds, an audio signal output unit used to export the audio-frequency signals after volume regulation to the speaker. The invention also discloses an audio processing method.

Description

technical field [0001] The present invention relates to a sound effect processing device and method, in particular to a sound effect processing device and method of a portable audio device. Background technique [0002] With the development of audio-visual technology and the continuous improvement of the integration of audio-video processing modules, more and more portable audio-video electronic products continue to appear, such as MP3 players, MP4 players, mobile phones, portable DVDs, etc., making audio-video field Electronic products are no longer just appliances displayed at home or in fixed places. Due to the small size and light weight of portable audio and video electronic products, various portable audio and video electronic products are widely used in daily life. [0003] Various portable audio and video electronic products usually have their own memory (such as MP3 player, MP4 player, etc.) or can read audio and video data stored in a certain storage medium (such ...

Problems solved by technology

[0004] However, when audio data is compressed, it will inevitably cause loss of audio data and distortion during subsequent reproduction. Based on the consideration of the cost of portable audio and video electronic products and user needs, current portable audio such as MP3 players and MP4 players Video electronic products only have ordinary music restoration and balance adjustment functions, and the sound quality played by them cannot be compared with the sound quality of the original CD

Therefore, if users use current portable audio and video electronic products such as MP3 players and MP4 players as sound sources, sometimes they only need to hear ordinary sound quality, and sometimes they want to hear music with high sound quality or special effects (such as BBE effect, 3D surround effect, etc.) the demand cannot be met

However, household audio power amplifiers do not have interfaces matching MP3 players and MP4 players, and power amplifiers cannot be carried as easily as MP3 players and MP4 players.
