Hi Tamara323
I am new to this forum and would have helped you if my trial had not unexpectedly expired, I was experimenting mostly with Audio Director, which oddly enough has not expired, so from memory, you simply import your sound file / recording into power director, and drag it to an audio track, if your audio tracks are used up you can add another audio track, and drag your file onto the track, you can also record directly into PowerDirector using a microphone plugged in to your computer, if your sound card is not good, then use a usb microphone.
As I said I can not access PowerDirector so I am unable to provide click by click instructions, am also amazed no one answered your simple question.
