Rendering in T is not as perfect as I thought

[headquest]

I wonder how long this has been a known issue.

About 24 hours..

Wow

Are you seriously suggesting that even though rendering issues have been reported by other users on this forum before (including the thread with the link on page 2), and even though the issues have been there *all along*, nobody "officially" took notice until now

Why are you asking me? I'm not official, I'm a user like you..

I would guess that previous reports may have got lost in the general noise of 'my host sounds better than yours' wars.. bug reports get taken much more seriously when they come with hard evidence, or reliable instructions to reproduce them..

...looks like a well-considered, gracious and comprehensive report to me

Perhaps Jules' genius is in software design (interface / workflow / data flow) and audiophile issues haven't been at the top of his agenda. My hope is that Mackie can contribute technology to help with the outstanding audio quality issues: dither, noiseshaping, pitch shifting, and time stretching - all matters they must have experience with.

Ok, I got the same result (Ithink) as gavriloP, meaning on all the files that I checked, the sound seems to cut abruptly when it gets to -75dB and below as can be seen here.



But isn't that a different issue than AndrewSimon samples, which had a very apparent -60dB noise in the file? That I can't replicate and I don't see that on my files (to my complete relief).

I'm very surprised that issue like this come out only now; I mean Tracktion is what, 2 or 3 years old now? Does this means that no audio engineer has put Tracktion rendering to the test until now? Surprising in the audio world, a world where specialist are usually the most nitpicker I've ever seen in any specialty (and I don't mean this in a bad way).

looks like some high frequency energy in the bottom sample that is not in the top one...

Looks like Audition.

headquest, your quote from the Mackie site doesn't say anything about them claiming that their dither is perfect.

This is pretty big, I gotta say. As everyone knows, I'm a staunch supporter of all things Tracktion-related, but I'm not going to say that this is 'nothing'.

On the other hand, consider the OTHER evidence: It hasn't come to light in a comprehensive and documented way until just now (despite headquest's thread-hunting expedition) and therefore that means that it hasn't been noticed by anyone's ears until now.

Should it be fixed? Of course! It's serious! But does this suddenly mean that all the music I've made and rendered in Tracktion sounds bad? No... history and common sense dictate that if nobody's noticed, then it doesn't 'sound bad'.

In the recent discussions regarding Digital Performer and Tracktion, it was universally agreed upon that Tracktion 2 'sounded better' than DP, due (apparently) to the 64-bit summing engine. Again, those are simply a bunch of ears, not a bunch of scientific tests.

What am I getting at?

The scientific tests prove that something needs to be fixed. For sure. It's gotta be one of the top priorities right now. But our ears should tell us to put things in perspective.

Staggering... An otherwise useful thread suddenly begins to veer dangerouslsy towards a bitch fest the moment headquest appears on the scene.

Give it a rest mate! Some of us are more interested in finding out the nature of any rendering problems that there may be than reading through your carefully crafted trolling.

[braj]

Wow, I agree with Lunch Money, that's pretty staggering as well

OK, I've reproduced this and am looking into it with Jules. Obviously this is a very high priority bug and we will do our best to get it sorted quickly.

Thanks Beno.

phew.
