    <p>I'm unsure what the problem is here, but here is my code</p> <pre><code>var btotal = []; var songarray = []; function whileplaying() { var playingSound = soundManager.getSoundById('aSound'); for (var i=0;i&lt;8;i++) { var ttotal = 0; for (var n=0;n&lt;32;n++) { var eblock = (i*32)+n; ttotal = ttotal+(playingSound.eqData.left[eblock]*100); } ttotal = ttotal/32; btotal[i] = ttotal; } console.log(btotal); songarray.push(btotal); } </code></pre> <p>To explain, while the sound is playing I get an array with a length of 8, summing up the EQ values of that frequency block. At the end I append this array to songarray, so the theory is that songarray is an array containing the sound's EQ data in arrays.</p> <p>The problem is that when I then get the value of songarray, it has however many arrays in it that I expected, but they are all identical, and are all what the last data point was, the latest value of btotal.</p> <p>So this code would run, and console would display (for example):</p> <pre><code>[42.743750000000006, 2.98125, 0.10625000000000001, 0, 0, 0, 0, 0] [38.859374999999986, 2.8, 0.09375, 0, 0, 0, 0, 0] [56.26874999999998, 21.831250000000004, 3.853125, 0.340625, 0, 0, 0, 0] [46.459374999999994, 19.584374999999998, 1.4, 0, 0, 0, 0, 0] [38.08125, 11.8, 1.0750000000000002, 0, 0, 0, 0, 0] </code></pre> <p>However the contents of song array goes like:</p> <pre><code>0: Array[8] 0: 38.08125 1: 11.8 2: 1.0750000000000002 3: 0 4: 0 5: 0 6: 0 7: 0 length: 8 __proto__: Array[0] 1: Array[8] 0: 38.08125 1: 11.8 2: 1.0750000000000002 3: 0 4: 0 5: 0 6: 0 7: 0 length: 8 __proto__: Array[0] </code></pre> <p>Which are all the contents of the latest btotal array. This leads me to believe that each entry in songarray merely points to btotal. So how do I make it so that each array in songarray is the value of btotal at the time I append it, and not merely a pointer?</p>

    1. COYour `playingSound` variable is the exact same in every iteration as you set it outside the loop, and never change it. Did you expect it to magically change?

    2. COSorry, I didn't explain that. What it returns is a sound instance in SoundManager, which data can be retrieved from. whileplaying() is called every 50ms

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
