Embodiment Construction
[0065] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0066] As mentioned in the background art, the currently commonly used method for enhancing the bass continuity is to greatly increase the gain of the bass equalizer (about 150 Hz to 400 Hz). figure 1 It shows an exemplary flow chart of enhancing bass continuity in the prior art, such as figure 1 As shown, the sound signal becomes a digital signal after passing through the analog-to-digital converter. After pre-attenuation, the overall amplitude of the signal is attenuated by a certain amount, and then processed by the low-frequency equalizer to set an appropriate frequency value (about 150Hz to 400Hz). , Q value and gain value, etc., to increase the gain of...

The invention relates to an audio processing method, an audio processing device and audio playing equipment, which can effectively improve the continuity of low-frequency signals in sound signals, ensure the bass sustain effect and ensure the overall auditory effect of the sound signals. The method comprises the following steps: acquiring an audio signal to be processed; frequency division processing is carried out on the audio signal to be processed, a first audio signal and a second audio signal are obtained, the frequency of the first audio signal is lower than a preset frequency, and the frequency of the second audio signal is higher than or equal to the preset frequency; performing compression reverberation processing on the first audio signal to obtain a low-frequency processing signal; and generating a target audio signal corresponding to the to-be-processed audio signal according to the first audio signal, the second audio signal and the low-frequency processing signal.
Description
technical field [0001] The present disclosure relates to the field of electronic technology, and in particular, to an audio processing method, device, and audio playback device. Background technique [0002] Bass effect and bass continuity have always been important pursuits in the design of audio playback devices (such as speakers), especially portable audio playback devices. Due to volume and size limitations, there have always been design difficulties in bass effect and bass continuity. Taking portable speakers as an example, because portable speakers have the characteristics of small speaker diameter, low power, small magnetic ring volume, short diaphragm stroke, and small cavity volume, the bass continuity is poor. In the related art, the bass continuity is generally enhanced by greatly increasing the gain of the bass equalizer (about 150 Hz to 400 Hz). However, this method will reduce the overall output range of the sound, and the overall sense of hearing is not good,...
