MP3的音量 [英] Volume level of an MP3

问题描述

我正在VB 6中工作.我正在播放mp3，并且如果当前歌曲的音量在歌曲末尾的MP3文件中降至某个水平以下，我希望下一首歌曲开始播放. .因此，我想从文件末尾开始向后扫描，并检查每帧的音量级别以获取正确的音量，以开始下一个mp3播放.它是一种交叉淡入淡出功能，基于音量级别而不是任意秒数.

我还需要在歌曲加载时(而不是在播放时)执行此操作.能做到吗任何帮助表示赞赏.

基本上，我只需要知道如何在任何给定的帧中读取mp3的音量即可.我知道如何做其他所有事情.

I''m working in VB 6. I have an mp3 playing, and I want the next song to begin playing if the volume level of the current song drops below a certain level in the MP3 file at the end of the song. So I want to scan backward from the end of the file and check the volume level of each frame for the correct volume to start the next mp3 playing. It''s sort of a cross fading function that''s based on volume level instead of an arbitrary number of seconds.

I also need to do this when the song loads, not as it''s playing. Can it be done? Any help is appreciated.

Basically, I just need to know how to read the volume level of an mp3 at any given frame. I know how to do everything else.
