Aliasing is not really depending on Hardware structure or software algorithms or programming skills.
It is only a matter of the simple speed of the distortion algorithms and the calculation power consumed by that.
Therefore I found it a bit distracting that a competitor makes comparison tests about aliasing - as if less aliasing was a technical innovation.
Probably the comparison was done to justify the use of a loud fan and the high price
If I felt face to face with them - I mean mentally - I would rather start a revealing comparison about innovations and sound dynamics and so on.
But I think that is not a mature way to deal with competitors.
So, back to the topic.
Aliasing cannot be avoided in digital guitar amps, there is no amp simulation without aliasing. It is just a matter how loud it is.
The Profiler produces a bit of noticable aliasing on the highest notes of the guitar, or by harmonics.
Those are not noticed by a majority of users, that is why we have our algorithms set as they are.
You need to use artificial test tones to make the aliasing more obvious.
This aliasing virtually non existent on deeper notes or chords, or in a band or recording mix.
That is why we think we have found the right balance.
Half of the comments in this thread are obviously not about aliasing.
Aliasing is created by very high notes through heavy distortion only!
Aliasing does not occur on clean or crunch sounds, and not with deeper notes or chords.
If your problem does not fall into this category, you should post an audio clip.
We have a large headroom of calculation power left, that I was planning to keep for future features and improvements for upcoming firmwares.
However, it takes only three seconds for me to speed up our algorithms for the next firmware.
But this would eat up some of the headroom for the future.
Still we don't know how much headroom we will use in the future.
What do you think?
