#1 Burning Software

When burning an Audio CD, after calling either
StarBurn_CdvdBurnerGrabber_DiscAtOnceRawPWFromFile
or
StarBurn_CdvdBurnerGrabber_DiscAtOncePQFromFile,
there will be a long delay. I guess it is processing the audio file(MP3), but I can't find a way to mesure the progress.

The delay is a little too long if there is no way to show a progressbar. Please advise.

After recording user data StarBurn SDK in DAO modes record manually lead-out. It's 16 megabytes in size (and do not forget about drive internal cache - it's 2-8 megabytes also and during "sync cache" operation it's also recorded to the CD media). So quite noticable delay (slower drive burns - more itme it takes to burn 18-24+ megabytes) at the end of the story is possibly. However you can easily calculate it using ( 16 MB constant + buffer size ) / burning speed. We can also add a callback indicating lead-out is now recording (with passing it's size as we do for general data track).

Let me know is it OK for you and what do you think.

Looks like I hadn't made myself clear.

I meant when burning Audio CD, immediately after calling those DAO functions but before actual data burning is started(even before CN_WAIT_CACHE_FULL_BEGIN is reached), there is a long delay of over 30 seconds, during the delay period, the harddrive LED blinks like crazy.

How to measure this time period?

Got it now! See, to burn disc in DAO mode you should always be clear upon exect track sizes in logical blocks (sectors). B/s you're writing lead-in with TOC information (and track lenghts) before writing actual data. With MP3 (and some other compressed formats) that's a problem. B/s you never know EXACT size of the uncompressed file payload. That's why before burning you need to play MP3 file very fast (as fast as machine can decompress MP3 stream) to get EXACT size of the file (uncompressed). That's what your machine is busy with Unfortunately this process is undeterministic from the time frame point of view. All we can do - report idividual file time get processing via callback. Would it be enough for you?

How can I do this? I can't find a callback number for this in the document.

They are not implemented yet. I've asked - would it be enough for you? If yes - I'll add this stuff ASAP.

It would be nice if you can implement this feature.30 seconds of darkness is a little too long for the end user.

Agree. Deal, so when I'll be done I'll notify you about preview version so you'd be able to check it out.
