I have used Sound Forge 4.5 and CD Architect for years to author CD that have a continuous, unbroken audio track. It allows me to insert track numbers for navigation. (For example live recordings) I am migrating to Windows 7, and I cannot install Sound Forge any more. (More specifically, I can install Sound Forge 4.5 off the original CD, but I cannot install the 4.5g update required to use ATAPI CD burners. It says Sound Forge is not installed). SF4.5 is getting pretty old, so maybe it's time to move on. What other software has the ability to preview an 80 minute audio WAV file and insert track markers?
