To find out who wrote this riddle, we can analyze the words and try to interpret their meanings.

In this riddle, the key phrase is "you've heard me before, yet you hear me again." This suggests that the answer is something that we have heard previously and will hear again in the future.

The next part of the riddle says, "Then I die, Til' you call me again." Here, the word "die" indicates that the answer is something that ceases to exist until it is called upon or summoned again.

Putting these clues together, we can deduce that the answer to this riddle is our own voice or sound. We hear our own voice all the time, but it "dies" or ceases to exist when we stop speaking. It only comes alive again when we call upon it by speaking once more.

As for who wrote this riddle, unfortunately, without any additional context, it is difficult to determine the exact origin or author of the riddle. Riddles like these are often shared and modified over time, making it challenging to attribute them to a specific creator.
