audio cd and source samplerate?

[smok3]

so i went ahead and did that cue file (wav sources), no problems, load in, burn!

 

after burninating i figured out that some files were 48kHz and they burned just 'fine'.

 

Well, not a bug, but one could describe that as 'dangerous behaviour'.

Your directshow filter has just converted it to 44100 (which is what CD-DA is), shouldn't be anything to worry about.

 

btw, 2.4.1.0 is a lot better for audio than 2.4.0.0 was - you should update.

I'am not saying that you should fix something, but obviously directshow did a bad work (i have just abxed this, comparing cd vs properly resampled version);

and it was really easy (maybe what i have here is borken dshow anyway...)

 

p.s. windows samplerate conversion quality is set to 'Best'

Sorry, I'm no audio guru and have no idea what this 'abx' stuff is / does.

 

Technically ImgBurn isn't doing anything wrong, so if there's something wrong with what's on the CD you'll be better off discussing the filters that perform the 48 -> 44khz conversion on a site that's appropriate for such talk (and I'm sure you already know about those!).

 

Maybe between you, you can find a better filter for such conversions. Of if in doubt, convert it yourself first in whatever program does it best and then burn the converted files.

[smok3]

sure , actually that is not a problem for me at all (but possible problem for ppl that are less audio savvy).

 

p.s. I can see that in latest version imgburn is doing scan pass to determine lengths, maybe add a samplerate detector and just warn a user before burning begins? (something like: not all of your files are the proper sample rate of 44.1, but dshow will do the conversion for you, the burning will continue in N seconds.. (or clicky abort))

I doubt less audio savvy people would be working with 48khz source flies

[smok3]

dunno, maybe they would, trying to convert DVD audio track to CD for example.

edit: anyway, lets see if someone can confirm bad samplerate conversion, maybe it is completely my specific-machine problem.
