Bass frequency power shifts...

Side wall makes a kind of comb filter but this is present all of the time and does not change with frequency.

Anyway... I'm not selling anything so any further convincing is out of the question.

@ illusions: it's possible but you can do it your self. Take any VST synth patch that you allready have used, program the cut off filter to make a full sweep with a bit of resonance, export a loop on 24 bit 44,1 kHz and than switch samplerate to 24 bit 48 kHz and export that same loop again. You don't even have to retune synth tuning...
samplerate alone makes quite a difference. Make A-B comparison and hear for your self. This takes about 5 minutes... so i really see no point in doing it for you.

ps: try not to use any VST that has internal oversampling (like Blue) or simply turn oversampling off.

Otherwise VST synth will process sound in higher samplerate and downsample it back to 44,1. When I think of it... the very fact that some synths have oversampling function also leads to some conclusion unless you believe that such function has no use at all.

From the scientific point of view such problems with bass sounds (and others) are caused by the "rounding" errors during the sampling process in the soundcard. If you have a bass line playing in the key of C (let's say a 130,81 Hz) your soundcard is processing this frequency trough 44100 samples (fixed mathematical points) per second. So since we have a bass line with 130,81 cycles per second and 44100 points per second we get that each bass cycle has to be calculated within 337,13018882348444308539102515098 fixed frames. Obviously soundcard will process this as a 338 samples and next bass line cycle will start in 338th sample and that is like 0,8698111765155569146089748491 samples later. Since Soundcard can't really delay the cycle it will simply ignore this difference and new cycle will not start from zero crossing but will have a missing part or a kind of phase delay if you like.

If you retune the C note to 128 Hz and calculate it within 48000 fixed points you get a clean 375 samples for each cycle. Further on... if you use Phytagorian (or similar non equal) temperament all other notes will be coherent with the note C and you'll have far less rounding errors, phase distortion and most certainly less problems with altering power when altering pitch.

Keep in mind that everything in nature is coherent with whole numbers. All life starts as a single cell and than divides in 2, 4, 8, 16, 32, 64, 128 cells etc. In nature there is no such thing as 337,13018882348444308539102515098. It's 337 or it is 338. Speakers also can not play 337,13 sound frames... they play 337 or 338 cycles. Everything in between is lost, damaged and makes various strange anomalies. Those anomalies when run trough effects, EQ's and other plugs get miscalculated for many times before you finish the track. Less errors in the start - better sound in the end.

@ undertow:
1 - why do you think that your opinion about my music would have any relevance at all?

In fact if one remembers your God given right to judge about nearly all non-western cultures and call them PRIMITIVE

than it is obvious that your judgment is clouded with your ego, ignorance and false self esteem. Since I'm a member of what you call primitive culture it's reasonable to assume that you'll find it primitive and that I don't make music for hi-tech ignorant people in the first place.

Some things can't be bought and some things are impossible to reach even when you use weapons with uranium ammo. However, I don't mind you believing that you are qualified for such judgment so any further discussion is futile until you incarnate at least for few more times in some primitive culture.

2 - In my primitive culture we have a strong belief about Newtonian physic and "modern" science. We believe that it is wrong most of the time.

So everything that I've said here is based primarily on my experience and my current understanding of the subject.

I assume that I don't know everything and I know that I'll never know everything. So for me the only relevance is experience and only knowledge from personal experience is what counts. You are free to believe what ever you want and that's the only thing that you can do because you have no experience about the subject.

Testing of the room resonance takes a microphone and about half an hour but you've never bothered to make one. Obviously in your case it's easier to be ignorant for the entire life and blame the others for it.

That way you can be the smartest kid in town without ever really know something from experience.

Of course... you can always prove me wrong with recording from the room test with any kind of measurable room resonance above 100 Hz. I assume that I don't know everything so who knows... maybe you'll prove me wrong.

3 - since this is a second time that you act in this advanced - God like manner I really hope that you'll get the picture this time. Since you're so smart it shouldn't be so hard for you.

In few words... I hope that you find your posts interesting and have fun while you write them because I certainly don't give a shit about your point of view from which you promote nazy-like ideology and in the same time pretend to be smart and advanced human being.

We all have a right to live but there's no law or weapon in the world that could make me consider you any way near human. Just keep that in mind for future conversation and I'll always be glad to remind you of that fact.
