No, of course not. Is this on the Mac or on Windows please (and which version of Windows)? And what type of sound card do you have (or are you recording through USB)? It might be an issue with your sound card drivers, and it is always worth checking the manufacturer's website to see if there is a later version available.
Perhaps you would like to send me a sound sample. PLease make this about 1 minute long and record to MP3 format to keep the filesize down. You can email it to:
