Abstract

The invention belongs to the field of sleep aids, and provides a sleep-assisted multi-source audio processing device, wherein the sleep-assisted multi-source audio processing device circulates and plays continuously and can meet the requirements of users for diversification and specialization of sleep aids music. The audio processor reads the compressed audio data of a single audio source in the decoding memory and outputs the compressed audio data in the ADPCM format, thereby effectively eliminating the interval between the circularly played single audio signals and realizing uninterrupted playback. In addition, the audio processor reads the compressed audio data of a plurality of sound sources in the decoding memory, performs data accumulation processing, and outputs and plays the compressed audio data in the ADPCM format, so as to meet the requirements of users for diversification and specialization of sleep-assisted music.

Description

technical field [0001] The invention belongs to the field of sleep aids, in particular to a multi-source audio processing device capable of aiding sleep. Background technique [0002] A good sleep and rest is an important guarantee for good health, sleep aids can help users sleep and rest. [0003] At present, existing music sleep aid devices help users sleep and rest by combining music players such as MP3. However, when this type of combined music sleep aid device is played in a loop, there is an interval between the music so that the connection cannot be smooth, resulting in poor user experience. , The quality of sleep and rest is not good. In addition, the existing combined music sleep aid intelligently plays the pre-stored single audio signal of a single sound source, and cannot arbitrarily accumulate and mix the pre-stored audio signals of multiple single sound sources to form a complex audio signal, which satisfies the user's need for music during sleep and rest. spe...
