Version: UltraISO 7.5.1.956
System: Windows XP Pro SP1 (unpatched)

The beginning of this year I extracted Roxio Easy CD Creator Basic 6.1.1.48 Audio Disc Image CIF to WAV files.  I confirmed the readability of these files.

This past week, I opted to burn discs of the material I extracted.  Upon playing I noticed a "click" at the start of each track.  Using Sound Forge I discovered a "click" precisely at 0.002 seconds of each track.  I attempted to burn other ways.  The same problem occurred.  I compared to the extracted WAV files and failed to find a "click".  I then uninstalled and flushed the registry of Easy CD Creator and reinstalled.  The same issue occurred.

I transferred the extracted WAV files to another computer with Easy CD Creator, and the same problem occurred, a "click" at precisely 0.002 seconds of each track.

I then used Exact Audio Copy 0.95 Prebeta 5 and Nero 6.6, oddly the same problem.  The extracted WAV files showed no "click" while the burned discs from all the disc creation programs did.

I then tested some recently downloaded WAV files, to my surprise there was no "click".  I then ripped WAV files from one of the original source discs and compared to the extracted WAV files, neither showed a "click".  I then burned a disc with the ripped WAV files, upon examination there was no "click".

I repeated this process using newly downloaded WAV files, ripping WAV files from source discs, then burning, and comparing to new burns of the extracted WAV files.  I repeated this process with Easy CD Creator, Exact Audio Copy, and Nero to eliminate any of those programs as a possibility.

I've concluded that UltraISO inaccurately extracts WAV from CIF, despite the extracted WAV, for whatever reason, failing to show a "click".

thanks,

tom
