推荐答案
好像我找到了解决方案.根据文档，AVAudioPlayer的音量可以在0.0到1.0之间.显然可以将其设置为大于1.0的值.通过增加音量，我可以达到相同的期望结果.如果未将其标准化，则增益会增加.
Looks like I found a solution. According to the documentation the AVAudioPlayer volume can be between 0.0 and 1.0. Apparently it can be set to a value greater than 1.0. By increasing the volume I was able to achieve the same desired result. While it's not normalized, the gain is increased.
