如何创建声音淡入效果

Question

using this code

for (int k = 0; k < 16; k++) {
    Track track = musicS.createTrack();
    track.add(new MidiEvent(new ShortMessage(ShortMessage.CONTROL_CHANGE, k, 7, 20), track.ticks() -3));
}

How can I make the volume fade out right before the song ends

Answer 1

从这里看 ，您可能想要将MidiEvent的滴答声设​​置为（track.getTicks（）-someNumberOfTicks）之类的值，以更改歌曲结尾的音量。

Answer 2

How many ticks are there in your Track?

You need to add a lot of MidiEvents to the end of you track, starting with where you want the fade to begin, gradually lowering the volume for each event.

Your code snippet is setting the volume at tick 0. Do you know if you are setting 7 to 'volume' or 'volume' to 7?

You need a new loop to add your MidiEvents to the end of your track.
