QMediaPlaylist播放每个项目间默认停顿时间比较长怎么解决

wsc

            利用QMediaPlayer播放本地录音文件，因为是片段的，利用QMediaPlaylist拼接音频，播放后QMediaPlaylist两个媒体文件间默认停顿时间比较慢，听上去比较别扭，setPlaybackRate只能控制播放速度，对两个录音文件间的间隔还是怎么优化或者控制两个媒体文件间这个停顿时间？

QMediaPlaylist *playList = new QMediaPlaylist;
if (payWay == QString("微信"))
{
playList->addMedia(QUrl::fromLocalFile(soundPath+"wx.wav"));
}
if (payWay == QString("支付宝"))
{
playList->addMedia(QUrl::fromLocalFile(soundPath+"zfb.wav"));
}
if (payWay == QString("银联"))
{
playList->addMedia(QUrl::fromLocalFile(soundPath+"yl.wav"));
}
// 根据金额拼接语音
QStringList listStr = money.split(".");
QString intStr = listStr.at(0);         // 整数部分
QString dotStr = listStr.at(1);         // 小数部分
qDebug()<<"intStr:"<<intStr<<"dotStr:"<<dotStr;
// 整数部分
if (intStr.length() == 1)
{
soundUnitTurn(intStr, playList);
}
if (intStr.length() == 2)
{
soundUnitTurn(intStr.left(1), playList);
playList->addMedia(QUrl::fromLocalFile(soundPath+"shi.wav"));
if ("0" != intStr.right(1))
{
soundUnitTurn(intStr.right(1), playList);
}
}
