Question

照常：

@IBAction func emailLoginButtonPressed(sender: UIButton) {

    UIView.animateWithDuration(1, animations: { () -> Void in
        self.facebookButton.center = CGPointMake(self.facebookButton.center.x - 500, self.facebookButton.center.y)
        self.twitterButton.center = CGPointMake(self.twitterButton.center.x - 500, self.twitterButton.center.y)
        self.emailButton.center = CGPointMake(self.emailButton.center.x - 500, self.emailButton.center.y)
        self.emailTextField.center = CGPointMake(self.emailTextField.center.x - 500, self.emailTextField.center.y)
        self.passwordTextField.center = CGPointMake(self.passwordTextField.center.x - 500, self.passwordTextField.center.y)
        self.loginButton.center = CGPointMake(self.loginButton.center.x - 500, self.loginButton.center.y)

    })

}

Answer 1

您可以使用play(playerObj,[start,stop])功能指定Spot model和start：

stop

或者，您可以计算总数据的子样本，并将其提供给audioplayer：

load handel;
playerObj = audioplayer(y,Fs);
start = 1;
stop = playerObj.SampleRate * 3;

play(playerObj,[start,stop]);

Answer 2

audioplayer的PLAY方法支持名为[startSample stopSample]的其他输入参数。因此，如果您想在5到7秒之间播放音频，则必须指定的范围为[player.SampleRate*5 player.SampleRate*7]。

如何使用Matlab以特定间隔播放音频文件？
