Dear User,
Please try to use the latest version of AVS Audio Converter to create ringtones for your iPhone - please see the file 'create iPhone ringtone.bmp' attached to find the way to select the necessary profile.
If I understood you right you need to insert pause between tracks while merging them, if so please follow this link to find the detailed instructions on how to do it. If you mean something else please specify.
When the ringtone is created, the program will offer you to upload the file to device and AVS Mobile Uploader will start, it will detect the device connected to your PC - please see the second attachment.
Please let me know if I can be of further assistance to you.
Kind regards
