KVR Audio

Ah, that "cut everything below -70dB". Hm. Shouldn't be an issue. The noise files are at -36dB, and in the "lowered faders" version, the last fader is at -15dB, which results in audio at -51dB, so it SHOULD be ok, even in the buggy Tracktion 1.6

Yeah, I am still working with 1.6 for almost 2years and I only noticed this (with my DT770's only) in just one song.

BTW yahoo keeps timing out

Stefan, I could do that with eXT, Project5v2, Storm 2, Samplitude (Magix AudioStudio), Logic 3x (Magix MidiStudio) and Sonar 4 .... (hm... - maybe I should also install my old version of Ntrack again... ) ... oh, and DeltaSP of course

And I could do it later today using Vegas. PM sent.

@ Stefan: e-mail with 2 mixdowns attached sent

Result from zeoy's test (this is what I wrote in my reply to him):

"Your renders are a bit off, they aren't exactly 0.5 seconds long (a few samples shorter). That's why you had problems with the cancellation.
I trimmed my renders to be starting and ending exactly like yours.
The 0dB version = difference at around -160dB after cancellation
The fading version = difference at around -160dB after cancellation
There are however a few spikes (2-3) in the cancelled audio, at around -110 to -130dB. It's quite obvious that these are due to some kind of a bug in one of the hosts. Which, I do not know. "

The resulting audio from the Tracktion mixdown was 22016 samples long, not 22050. One sample was missing in the start, and a bunch missing in the end of the render. Dunno why

I'll mail the files to you, jens and nuisance sonore.

Keep in mind that the host must support 32bit wav's and 32bit renderings (I've seen hosts that doesn't....).

Those spikes @ -110 to -130 dB are worrying me ... huge differences

Regarding my shorter renders, maybe the problem is that I checked the "only render marked region" setting and maybe the markers were a bit off.

Thanx for taking care of my lousy renders. I feel better now

Those spikes could be due to some fishy bug in the tracktion rendering. We already know that it is buggy, so I wouldn't fully rely on it doing this correctly either

We'll see how the other renders turn out.

When I said that these spikes are worrying me it was clearly sarcastic. I hope that was clear. Even if it is due to T1's buggy renedering don't think it's a major issue in real life situations (I felt like defending my beloved T here

)

Ah. Heh. Well, it's not like you can hear them

Such is the case with Vegas unfortunately, 16 and 24 bit only...

EnergyXT, faders at 0dB, difference from podium at ~ -160dB. No spikes.

I guess one would have to go with 24bit then
