Aliasing test on real music, can you spot it?

[Ploki]

Aliasing reflect back distortion adding harmonics. In the zip file you find also the dry signal, if you want you can download FrontDAW demo, and try it yourself.

i tried FrontDAW way back and it's whatever - i'm just saying that either FrontDAW is broken or there's something you didn't account for, because i've tried a lot of things with OS and AA, different filters, different factors, different plugins, and never ever has it happened that OS would behave like a -5dB low-shelf, that simply makes no sense.

It would need to mirror at exactly the bass frequency with phase inverted and almost as loud as the original for that to happen, and that's extremely unlikely considering the modest amount of distortion you applied.

It appear the version i've used had a bug as El°HYM wrote, if you account that FD is used on every track and every bus, things stack up pretty easilly and so this could be the reason

Anyway apart from that here we talk about aliasing, and that's what people should try to spot, or at least understand what's the best sounding between A and B, so if you think a boost on low freq can help you to match the 2 versions to have a better comparison, feel free to do it, i've included the WAV instead just to do a video for that reason, so people can play with the audio file in the way they prefer to have what they think is the best comparison method.

I'm interested to do a test to see what people perceive to sound better between some aliasing or a steep LP filter at nyquist for different plugins and different kind of processing

When doing tests like this: I'd suggest at least using Reaper. It's efficient, has excellent oversampling, and wouldn't have bugs like this. What the heck is a FrontDAW anyway?*

*I'm not really asking but seriously never even heard of it.

I'm using Reaper, FrontDAW is not a daw, is a preamp/soft saturation plugin that comes with his OS as almost every saturator out there

Gotcha. Thanks for clarifying.

Why not just take a standard Reaper project with a mixed song using various plugins, turn off Oversampling in all plugins. Then run a bounce out using Reaper's oversampling options or not?

EDIT: and the reason I suggest that is because some plugins have great oversampling implementations, while others leave a lot to be desired even with oversampling. Letting Reaper do it effectively runs the audio at a higher rate and using R8Brain for the resampling. As long as you stick to reasonable OS settings (4x), most plugins will play nice with it.

The idea to turn on/off OS on various plugins on a project it's interesting, may have been a 5th test. If in the future i will do another test like this one, this is certainly something i will.

About Reaper OS i think it's an incredible feature to OS plugins without oversampling, or as you wrote to use this one instead the native isn't good.
Although there are different approach to OS, and if the plugin developer is a good one, he should try and chose the right one accordingly with the plugin he is developing.

This is something i usually try to listen while testing and reviewing plugins, cause my ears are kinda sensitive to certain OS, and so the plugins i chose to use take this factor in consideration.

I also appreciate when devs give different OS options, cause accordingly to the sounds and settings you may want to use something different.

Gotcha. Thanks for clarifying.

So whats the Result? Let the people know... now.

Still waiting more entries, the more data the more interesting the result will be.
As i told in the video i didn't placed any deadlines because of that.

With the Analog Vs Digital Eq emulations blind test, i'd loved to have more data at the end of the process and so now i don't wanna rush it.

But no worries i will get with the results... soon or later...

Reveal will be done in few days.

Just a question, for the people who comes later and wanna have fun with this test too.

Any way to hide the results as spoiler? Cause i don't find any related option

My guess: No, you cannot hear the aliasing in a mix. Results will be mixed.

You can't go based on the fact results with be mixed. What needs to be compared are people who get it right, and consistently get it right.

[El°HYM]

Let us hear the Delta - signal too & then we can talk about who cannot hear Aliasing.

[Frankie.T]

Time for the test reaveal.

Here's the video, even if it turned out into something different due to the results

If you just wanna go straight to the result, and so which was the OS between A and B on each test, in the following link you find it the OS response

It's just a webpage, i don't write them here, cause i don't wanna spoiler the results to people who wanna try it, and i don't see any spoiler feature in the forum
