Yes, I realise that playing an audio file and converting it to CDA are independent issues. I mentioned playing out of completeness - the main point was that Nero could make a successful audio CD from the above files but ImgBurn couldn't -- a small point. Anyway, as you requested I emailed a screenshot of the audio Codecs from installedCodec. In case, they are of general interest, I present it here: It seems that the above problem is mine alone, so, if you are too busy to help any more, I understand. Indeed, I would prefer you to move on to issues of concern to others. Thanks very much for your help so far. Robin

That means the so called "on the fly copy" will be implied? Glad to hear this I would have thought a one-click copy via an image (2-stage) would be better than an on-the-fly? The latter could have problems due to differences in read/write speeds, buffers, etc.

A further comment on the file 'Seeyablues 22sec.wav': it not only plays correctly on my PC (every App that plays audio), but, when burnt to an Audio CD using Nero 7 Essentials it played correctly in WMPlayer! Yet, as mentioned above, it will not play from a CD made by ImgBurn!! Robin

Yes, I confirm that this file burns to an Audio CD but plays garbled (hard to recognise) in Window Media Player. In GraphEdit I get the same as you did and when the track is ripped to WAV from the CD it is 44.1 kHz as it should be (like your RAW) but also garbled. In SoundForge their envelopes looks much the same, but, do they sound the same?? Are you saying all is well - that the RAW is 'identical' and therefore the CD track will sound the same - that you cannot reproduce the problem? Or are you just asking for me to confirm (as in the quote)?? Thanks Robin

But still useful! It helped to finalize the understanding for this 48 kHz file that didn't fit the pattern. Thanks

Yes, it makes sense that it is 8-bit! In Gspot and Explorer it appears as 48 kHz and 768 kbps. Its size is half what it should be: only 93.4 kB/sec and appears in Adobe Premiere as 'compressed stereo' rather than '16-bit stereo'! So DirectShow can handle 48 kHz 8-bit correctly but not 16-bit! In any case, this file is an oddity for me -- I am still concerned about the feeding of 16-bit 48 kHz WAV files to an Audio CD! Robin

Thanks LUK. I have just sent a 22 sec sample.

Thanks. I fully understand and am pleased that ImgBurn goes to the trouble.

I have checked them all in XnView and in Premiere: they are all 16 bit! The properties for the 'Default DirectSound Device' filter are the same for all the 48 kHz files, viz: 1 format tag, 2 channels, 48000 samples /s, 192000 Avg B/s, 4 Block Align and 0.00 rate! This is no help. The only difference I could find between the single 48 kHz file that played and the others that did not was as follows: (1) Gspot gave its Codec as 0x0007 (MULAW) rather than PCM audio (2) when opened in Premiere, it was indicated as 'compressed stereo' rather than just '16-bit stereo' and (3) its file size was relatively low, only 93 kB/sec, which is half that for the files that would not play: at 186.8 kB/sec (normal, being 10.9% more than that for the 'good' 44.1 kHz files) . I could send you a short file that doesn't work, maybe 22 sec (4 MB). But how would I send it? To this forum or directly to you? Thanks Robin

This comment by Blutach reminded me of the reason for this thread. It was initially requested that a one-step disc copy mode be added. I suggest that because we have brains, we would want the operation of ImgBurn to continue to grow in a logical fashion and to improve efficiency where possible. To this end, it would be rational to think of a natural extension to a one-click disc copy mode (not one-step). This would then combine the Read (to ISO or BIN) and the Write modes into one seamless process. Being via an image file it would be safe - just as good as the separate operations of Read and Write. It would also add efficiency. Rather than coming back to the PC twice to copy, once would be enough! Anyway, this is my twopence worth. And I think the logical structure and thoroughness of ImgBurn is crying out for this addition (if not ImgBurn, then many of us)! I am not trying to be cheeky, just hopeful. Regards Robin

As mentioned above the extension for the PCM/WAV files from Premiere is '.wav' as supplied by Adobe Premiere. All 44.1 kHz WAV files play from the Audio CD made by ImgBurn (in WMPlayer). ' In Gspot their Codec is seen as 'PCM audio' & 'No Codec required'; and in GraphEdit they link through 'Wave Parser' to 'Default DirectSound Device'. 1 WAV file, at 48 kHz (unknown source) also plays correctly from this CD. In Gspot its Codec is seen as '0x0007 (MULAW)' and 'Codec not installed'!!. In GraphEdit, it linked to 'Wave Parser', then 'ACM Wrapper' and to 'Default DirectSound Device'. However, 3 WAV files I tried were exported from Adobe Premiere at 48 kHz (always at 48 kHz). When ImgBurn's audio CD plays in WMPlayer the audio is as loud as the original but so garbled it cannot be recognised! In Gspot their Codec is seen as 'PCM audio' & 'No Codec required'; and in GraphEdit they link through 'Wave Parser' to 'Default DirectSound Device'. So all looks OK in GraphEdit -- there being no errors issued! Can you make sense of this?? Regards Robin

I guess this is a happy ending to this little thread! Thanks, LUK and Blutach Regards Robin

Thanks LUK. It was 'Access is denied' because my browser (XnView) or WMPlayer had been pointing to the drive. So, no problem and all's well!

I just did 2 things: I checked the dates of my ISO & BIN files made by ImgBurn (late March) and when version 2.4.1.0 had been installed (12 April 08). The result: all my tests that encountered Read errors were NOT with the latest version. So, I reset to 20 Read error retries, unchecked 'Ignore read errors' and re-saved in Read mode the 1-session data disc and the 17-session data disc to ISO and BIN, respectively. There were no read errors!!!! So, no problem. Just the Question: why is v. 2.4.1.0 free of the read-error problem that affected 2.4.0.0? Thanks for your suggestion to look at the version I was using.

I have had a look at GraphEdit. I could not find its EXE on my PC (searched), so, I downloaded it (not installed) and checked out the Windows site for DirectShow and GraphEdit. It is not clear to me how best to use these facilities -- there is danger of upsetting the Codecs already onboard! So, I guess I will live with the fact that I cannot add PCM/WAV files to an Audio CD and if I need audio stuff from Premiere I will export as MPA instead. However, the bottom line for me is that other Apps (mentioned above) on my PC will play the PCM/WAV files !!????? So my PC must have the necessary tools. Thanks again.
