Converting large files to mp2 bwf crashes

[razorhack]

When I try to convert a large a wave file (48000 hz) dmc throws up an error message when the conversion is finished refering to 'instruction 0x7c910f29 referring to adress 0x00000000 could not be read' The file in itself is not complete and is corrupt after a few minutes.

How big is big? And what are the specs. for your wav file (bits, frequency, channels)?
Try enabling Professional Frequency Conversion (from dMC Configuration; Start>All Programs>dBpowerAMP Music Converter>Configuration>dMC Configuration).
Also try reducing the priority level for your conversion (if you have Power Pack) to Below Normal (set from the window that displays the progrwess for your conversion).

Good luck and let us know how you make out. If the above ideas don't work, do send the specifics on your wav file.

Thanks for the quick reply. The wave files in question is +500mb in size 16 bit 48000. I have professional frequency conversion enabled and have no problem with smaller files. I have tried to use lower priorty but it don't seem to work. I have download the latest beta version of dmc without much success. Any help is much appreciated!

Re: Converting large files to mp2 bwf crashes

Are you sure your wav file is not corrupted (for example, can you play it all the way through)? What are your bwf settings (bitrate, channels)?
If the wav file is ok, my only guess right now would be to try to increase system resources while converting this file by turning off what background programs you can and seeing if you can increase your system's ram cache.
I did manage to rip a whole album ripped as one track mp3 to bwf 192 kbs. without problem. Of course the source file was much smaller than your wav file is.

Re: Converting large files to mp2 bwf crashes

It has dawned on me that the quicker test of the original wav for corruption is to do a test conversion (right click, convert to, choose "Test Conversion (No Write)").

I was able to convert my mp3 whole album to an 882785 kb 48 khz. wav and convert that to 48 khz bwf (I used the max. bitrate of 384 kbs, just to push the conversion to its maximum limits). Conversion seemed to go ok (although see below). I could test convert the bwf file without trouble.

Also, I found that dAP (r3 beta5) won't play bwf files with bitrates of 256 or 384 (at least not at 44.1 or 48 khz). It will play bwf files at either frequency if they are at 192 kbs bitrate.

In addition, I did try converting a 48 khz bwf file with bitrate of 384 kbs and then convert the resulting file to FAACmp4 (at 100 setting). In 2 out of 2 trials I ran into problems. Although in each case the conversion seemed to go well, but it generated an error message at the end of the conversion and the program closed. However, I could play the resulting file in dAP. In the second case there was no crash but the resulting mp4 file could not be played. In a third trial, converting from 48 khz, 384 kbs bwf to mp3 (Lame, alt-preset-standard) everything when fine.

I don't know if this casts any light on your predicament or not, perhaps this will be clear to me sometime.
