随着科学技术的高速发展和人们生活水平的不断提高，近年来，音频播放设备例如随身音乐播放器、智能手机、智能音箱等逐渐在人们的生活中普及。随着网络技术的发展，音频播放器例如智能音箱或智能手机可以接入网络，并通过网络获取海量的可用于播放的音频文件。其中，音频播放器所获取的音频文件可能是由多家提供方所提供的，同时音频播放器所获取的音频文件还可能包括多种内容类型。例如，音频播放器所获取的音频文件可能是某网页播放器里“我喜欢的音乐”歌单中内容为古典音乐音乐会现场录音的音频文件，也可能是音频播放器上储存的内容为相声的音频文件，甚至可能是音频播放器的提示语音或提示音等。响度是电信号转换为声波振动时度量声音能量的一个指标，是人耳听觉对声音强弱的主观感受，当用户为音频播放设备设定的音量一定时，可能使音频播放设备播放一个提供方所提供的内容类型为相声的音频文件时输出的响度刚好适合用户听取，而该音频播放设备播放另一个提供方所提供的内容类型为古典音乐的音频文件时输出的响度较大或较小不适合用户听取，因此在音频播放设备播放音频文件时，需要用户针对不同类型的音频文件调整响度增益值或音量值，使音频播放器输出的响度适合自身听取，从而损害了用户体验。With the rapid development of science and technology and the continuous improvement of people's living standards, in recent years, audio playback devices such as portable music players, smart phones, and smart speakers have gradually become popular in people's lives. With the development of network technology, audio players such as smart speakers or smart phones can access the network and obtain a large number of audio files available for playback through the network. The audio files acquired by the audio player may be provided by multiple providers, and the audio files acquired by the audio player may also include multiple content types. For example, the audio file obtained by the audio player may be the audio file of the live recording of a classical music concert in the "My Favorite Music" playlist in a web player, or the content stored on the audio player may be cross talk audio files, and may even be the prompt voice or prompt tone of the audio player. Loudness is an indicator that measures the energy of sound when an electrical signal is converted into sound wave vibration. It is the subjective perception of human hearing on the strength of sound. When the volume set by the user for the audio playback device is constant, it may cause the audio playback device to play a provider. When the provided audio file whose content type is crosstalk, the output loudness is just suitable for the user to listen to, but when the audio playback device plays the audio file whose content type is classical music provided by another provider, the output loudness is larger or smaller. It is suitable for users to listen to. Therefore, when an audio playback device plays an audio file, the user needs to adjust the loudness gain value or volume value for different types of audio files, so that the loudness output by the audio player is suitable for their own listening, which damages the user experience.
为了解决上述问题，本公开的实施例提供的技术方案中，通过获取音频文件以及用于播放音频文件的音量值，其中音量值能够反映用户希望音频播放设备输出响度的大小，通过确定音频文件的音频类型，获取与音量值以及音频类型对应的目标响度增益值，并根据目标响度增益值对音频文件进行响度增益调整，其中目标响度增益值为适合在该音量值下播放该音频类型的音频文件时对音频文件进行响度增益调整所使用的增益值。因此当音频播放设备播放经过上述响度增益调整后的音频文件时，在无需用户整响度增益值或音量值的前提下，使音频播放设备所输出的响度为适于用户听取该音频类型的音频文件的响度，从而改善了用户体验。In order to solve the above problem, in the technical solution provided by the embodiments of the present disclosure, by acquiring the audio file and the volume value used for playing the audio file, the volume value can reflect the output loudness of the audio playback device desired by the user, and by determining the volume of the audio file Audio type, obtain the target loudness gain value corresponding to the volume value and audio type, and adjust the audio file according to the target loudness gain value, where the target loudness gain value is suitable for playing the audio file of this audio type at this volume value The gain value used to make loudness gain adjustments to the audio file. Therefore, when the audio playback device plays the audio file after the above-mentioned loudness gain adjustment, without the need for the user to adjust the loudness gain value or the volume value, the loudness output by the audio playback device is suitable for the user to listen to the audio file of the audio type. loudness, thereby improving the user experience.
