Garage band audio recording for ringers

iOS and iPadOS

Hello everyone. I got my new Iphone yesterday. I was wondering, is there a possibility that you can cut out the silence at the end of an audio recording you make in garage band? I have been making recordings using youtube on my IPad and garage band on my phone. I intend to use these recordings as ringtones. But, if I stop recording before the 32nd limit, there is a really long bit of silence.
