Problems solved by technology
[0004] First, because the parameters of the ADC (Analog to Digital Converter, analog-to-digital converter) chip register in the Bluetooth terminal have been pre-set when the Bluetooth terminal is collecting sound signals, the audio output terminal in the Bluetooth terminal cannot adjust the volume, and then Can not meet the client's personalized needs for audio volume
[0005] Second, when using traditional proportional audio gain to adjust the volume, the problem of sound distortion after gain is caused by the inconsistency of the loudness gain at different frequencies within the human hearing threshold

The embodiment of the invention discloses an equal-loudness volume adjustment method and device applied to a Bluetooth terminal and electronic equipment. One specific embodiment of the method comprises the following steps: acquiring an audio data set; based on the audio data set, determining a frequency of the audio data set and an average amplitude of the audio data set; based on the frequency of the audio data set and the average amplitude of the audio data set, performing gain processing on the audio data set to obtain gained audio data. According to the embodiment of the invention, an equal-loudness volume adjusting method is realized, so that the personalized requirement of a user on the audio volume is met under the condition that the minimum distortion degree is ensured.
Description
technical field [0001] The embodiments of the present disclosure relate to the field of computer technology, and in particular to a method, device and electronic device for adjusting equal-loudness volume applied to a Bluetooth terminal. Background technique [0002] With the development of the times, various voice smart devices have emerged in recent years, and the volume adjustment technology based on Bluetooth terminals has become the key technology of Bluetooth voice. At present, the commonly used volume adjustment technology often adopts the traditional proportional audio gain to adjust the volume. [0003] However, when using the above method to adjust the volume of the Bluetooth terminal device, the following technical problems often exist: [0004] First, because the parameters of the ADC (Analog to Digital Converter, analog-to-digital converter) chip register in the Bluetooth terminal have been pre-set when the Bluetooth terminal is collecting sound signals, the au...
