It depends on other factors even, like sampling frequency. <br><br>To confirm your data you can run <br><br>audiotestsrc num-buffers=150 ! fakesink -v<br><br>and observe the last timestamp. by seeing this timestamp you can calculate the num-buffers to adjust to 15 seconds.<br>

Hi all,<br>
I want to create a sine wave audio signal of a defined length, e.g. 15s.<br>
The element audiotestsrc has the property num-buffers. If I set the<br>
property to a defined value the signal gets an EOS. Set the property to<br>
num-buffers=150 the signal has length of about 9s. Is this the right way<br>
to calculate the length of the signal by number of num-buffers or is<br>
there another possibility?<br>
<br>
