Is anyone other than me having this problem in MSpectralDynamics?

[Jedinhopy]

Has anyone noticed that the frequency response that it has captured from the audio signal does not sound exactly the same when loaded as a preset after having saved it as a preset?

When i create my MSpectralDynamics preset.
It does not matter if i save that preset inside the MSpectralDynamics vst plugin or as a .fst preset in FL STUDIO.


And then when i load the saved preset.
I hear that it does not sound exactly the same as before.

I think MSpectralDynamics can't save presets without making them sound different when they are loaded.




Am i alone with this problem?

What sort of difference?

I tried this here:
-- same audio clip on two tracks,
-- MSpectralDynamics on both tracks,
-- Captured the analysis on one track
-- saved it as a preset
-- loaded that preset into MSD on the second track,
-- inverted the phase of the second track

On playback the two tracks almost nulled out - peak level less than -51 dB. MMultianalyser did show a small difference (but could that be due to timing?):



Edit: On closing the project and re-opening it, the two tracks null out perfectly. So it seems to be all OK here.

Not for me:

Which tool is that?

I've reloaded my project today: the "capture" track and the "preset" track now null out completely here.

I rendered each track and disabled MSD. On playback, using MAnalyser on each track the spectral content was the same here. Here are a few comparative screenshots (the upper one is the "capturee" track, the lower one is the "preset" tracK):

To help with the investigation is there any chance of uploading a small problem audio clip and the preset?

iZotope RX 2.

Here is the audio file in question:
http://www.speedyshare.com/vu5Du/The-song-100bpm.wav

I created the preset by first setting:

SMOOTHNESS to:
0.00%.

SLOPE to:
0.00 dB

OUTPUT GAIN to:
0.00 dB

Then pressing the CAPTURE button and then release that button in the most intense loudest part of the song.
And then set the THRESHOLD back to:
-80.0 dB

And then use these settings:

SMOOTHNESS to:
0.84%.

SLOPE to:
+1.56 dB

OUTPUT GAIN to:
+24.00 dB

And then save the preset.
And finally load that preset.



You hear the difference?

'Fraid not (even after I had turned down the tracks to avoid a level of +14.8 dB )

The "capture" and "preset" tracks nulled out at less than -92 dB here.

Have you tried feeding MSpectralDynamics with audio signals louder than (normalized) volume?

[MeldaProduction]

Well I tried with some audio I have here, I didn't do anything special, just captured something, increased temp gain to make it more pronounced, listened, save it as preset and loaded it back. Heard no difference really...

Why do i hear a difference?

[MeldaProduction]

No idea. How about sending me a FL project (or what host you are using) with instructions how to do that?

[Jedinhopy]

So now i will only use MSpectralDynamics for working on a single audio clip.
And then when i am done with the processing.
I render out a new audio file.

I will not save the preset.
I will not save to a .flp file.

Because it would not sound exactly the same when the preset file or the project file is recalled.

[MeldaProduction]

Sure you can do that or you can send me something I can actually try to simulate it on... or not...
