Titanium For Mac - Distortion/crackling

[dubbo 0]

Hi - I just bought titanium 11 to make some audio only DVDs with PCM audio - the process is very simple and easy . However the final encoded audio is faulty. Compared with the original tracks (PCM 16-bit and 24-bit / 44.1 and 88.2 ) the encoded audio is distorted and static crackly.

 

Also I have found that if I even preview the assets in Toast before burning the same problems are apparent. I can confirm this happens even with an aiff cdda track.

 

Could this be an issue with core audio - I noticed recently that some other players on mac struggle with some files - eg. VLC has distortion problems playing 44.1/24 tracks (from HDTracks) whereas Play and iTunes do not . Is titanium using core audio?

 

At the moment at I am at a standstill - the sound quality is simply unacceptable. I am about to try discwelder to see if the same problems occur.

 

Just out of interest - I know the VOB container is mpeg like - can someone confirm that PCM files are NOT mpeg compressed.

 

thanks

well sonic heaven has been resumed ..

 

The solution - I used Audiofile Engineering's Wave Editor to resample the 44.1 files to 48kHz (trial available) - apparently it uses something called "Izotope SRC". And now Achtung Baby / U2 from HDTracks sounds incredible through my DVD player / system at 24-bit.

 

Just for comparison I left some of the original FLAC 24/44.1 tracks on the DVD and let Toast change 44.1 - 48 , result: same as before distorted / lack of soundstage.

 

I intend to also try SOX for the resampling - it is free.

 

Apart from the sample rate issues the whole process with Toast was flawless to make an Audio DVD complete with menus - up to 24/96 resolution of course.

 

Hope this helps others.
