    Annoying bug in CD writer

    I don't know how to explain this as it is very strange. I added some files to the CD writer to burn, then decided I didn't want them, so I cleared the list. A few seconds later, one of the files I had cleared popped back into the list out of nowhere.

    A few more seconds later, another one showed up, and this process continued on and on. I even closed the program, and it re-opened itself and added another file

    Once it had finished doing all the files I had originally selected and then removed (which it did out of their original order), it kept on going, adding multiple copies of files it already added. Eventually, it stopped, after it added a ton of files. It didn't add second copies of all the tracks, just some.

    And it keeps on doing this when I try and clear the list. This is extremely annoying.

    Also, why does it have to convert the files to Audio CD format? It even does this for WAV files, which other software seems just fine with burning natively. It is kind of annoying, because it takes a while, and the process is not multithreaded as other encoding/decoding tasks are.

    Perhaps you had a conversion to CD Writer running in the background? If you restart Windows then clear the list, are any new files added?

    You know what, I think that is it. I had it minimized and didn't realize.

    But I still have an important suggestion. For whatever reason, the operation of converting the files to Audio CD format is not multi threaded, and I have 13.1 reference. And when I add FLAC files, it takes forever to convert to audio CD.

    But, if I first convert the FLAC files to WAV (which is extremely fast, but still not multithreaded), and then convert the WAV files to Audio CD (again not multithreaded), the process is very quick. So the efficiency of conversion to Audio CD could definitely be stepped up.

    Also some other stuff posted here would be great:

    I know some of it is R14 material, but still great to keep in mind. Very forward looking features.

    The slowest part is the HDD, decoding FLAC to WAV takes almost no CPU.

    Yes, but FLAC to WAV is very fast and WAV to Audio CD is also very fast.

    It's FLAC to Audio CD that is very slow, significantly slower than both of the above processes combined.

    And none of these operations run on multiple threads, which would also speed things up.

    I think Spoon is saying multi-CPU would have no speed advantage, as your HDD would be bottlenecked trying to move that much data.

    I see. Well that may be true, with traditional hard drives. But SSDs are gaining popularity, getting bigger and cheaper, and they could certaintly take it.

    But, this still dosen't explain why FLAC --> Audio CD is much slower than both FLAC --> WAV, WAV --> Audio CD combined.

    Yes, I've noticed this bug? in CD Writer.

    Converting FLAC tracks to WAVE in CD Writer takes 4 minutes and 50 seconds.

    Converting FLAC tracks to Wavpak in Music Converter takes 22 seconds.

    Why the big differance? It's obviously not down to CPU processing or
    Hard Disk reading/writing.

    Another CD writing program I use takes 30 seconds to to add the FLAC files
    to the CD writing list and then start writing the CD. In fact I continue to use
    this program to write CDs because of this bug?

    One other thing. It would be useful to have a 'quick erase' of re-writeable media as well as the full erase.
