Note: this question has connection to my prev question : are the step 2 and i manage to get through it and step 3 too. But step 4 i don't understand how to read the formula

Step 3. Apply a two-level DWT to the left-channel of the stereo audio signal. The DWT operation produces the one-dimensional sub-bands shown below in Figure 1, where A2 is the approximation sub-band, and D1 and D2 are the first-level and second-level details sub-bands, respectively. Its important to note here that the decision was made to adopt the two-level DWT since it gave better results than higher DWT levels.

so here is step 4 and it's formula :

any advise how i supposed to read it?
