after @Mulvya comment I changed my for loop to
var volStr = '';
for (var i = 0; i < arrPairs.length; i++) {
volStr += "volume=enable='between(t," + arrPairs[i].start + "," + arrPairs[i].end + ")':volume=0";
if (i !== arrPairs.length - 1) {
volStr += ",";
}
}getting rid of the space between each grouping and it worked beautifully.
