DRY principle on audio processing block

In my audio processing code (audio processor) I have something like below code. I am trying to avoid this below repetitive code. Wondering if there is any better way to write this code?

Code is just an illustration to understand the problem: I have several audio processing blocks where the audio of one block is passed as input to second block and so on until the final processed output. There are 4 major components of this 'blocks': Initialization, processing, reset, and de-initilzation.

    /* some code here to initialize audio processing blocks */
    //snip

    /*
     * order of audio processing is important here.
     * Is there any way to avoid writing below code
     * for every processing block that gets added in
     * future in c++11 perhaps??
     */
    if (t1) {
        t1->process(iFrame, oFrame);
        iFrame = oFrame;
    }
    if (t2) {
        t2->reset();
        t2->process(iFrame, oFrame);
        iFrame = oFrame;
    }
    if (t3) {
        t3->process(iFrame, oFrame);
        iFrame = oFrame;
    }
    /* 
     * if in future we want this way t1 - > t3 - > t2 then code change is required, 
     * is there any way to avoid this code change
     */

Please suggest right way of dealing with this.
