Phase inverter

[tracert]

I have do a mono stream phase invereter but dont' work, Why ?
i have uploaded my schematic.

Firstly, here you should use Float (F) instead of Integers (I).
If this would not help, tell, please, "don't work" how?

SM isn't that strict. Using an integer here works also.

It´s quite easy to test simple schematics, e.g. like this

well no it's ok to use the integer -1 to revert the phase and it should work - anyway we usually call "stream" the grey stream carrying multiple voices information, this is better to be called an "audio mono signal" instead.

I need to rotate the phase of incoming signal , but the oscilloscope, show me the same phase of the input signal

rotate the phase

Sorry if this is a silly question, but do you really mean 'rotate the phase' or do you mean 'invert the signal' - it is only the same thing for certain symmetrical waveforms, yet many technical documents still mix them up.
Multiplying by -1 will invert a signal, but to phase shift (like the phase input to an oscillator) requires delaying the signal in time.

anyway we usually call "stream" the grey stream carrying multiple voices

I wouldn't agree with that - a stream is so called because it carries a continuous flow of information transported at a guaranteed rate, which could easily apply to any information e.g. also video. So mono, mono4 and poly are all types of stream, in contrast with green/yellow data which consists of discrete events.

ok, my d.a.w. dont have a button to rotate (180) the phase of incoming audio signal, i need a simple software to do this...
some help ?

[lesobrod]

It looks like intricate mystification )))
I agree about Integers (but sometimes it may be important), so your very first schematic must work.

Multiplying by -1 will invert a signal, but to phase shift (like the phase input to an oscillator) requires delaying the signal in time.

Cool, as always from Trog.
But we should start from symm waveform and just damn invert it!
It seems something wrong at the rest part of schematic, so OSM, please!

Ah yes, so it is really an inversion that you need - many makers of audio hardware/software call this '180 phase', but technically, that is not correct. Mostly people understand what is meant, but for making synths the difference is more important than for a mixer etc.
(Sorry for me being such a geek - I do not think you are stupid, you are not to blame if the 'teachers' told you wrong!)

Your *-1 idea should do what you need - so if you use a Saw wave you should see something like Theun's picture, with wave going 'up' instead of 'down'.

If this is not happening then you should post your design so that we can take a look, maybe there is a problem elsewhere that needs fixing, or a VST export is not working correctly.

something like

Code: Select all

streamin in;
steamout out;

out = in * -1;

or not?

[lesobrod]

or not?

Well I hope this code works as first picture ( only if SM was not designed by aliens)))

[CoreStyler]

What i dont understand is...
did the rigth example will require the same amount of CPU of the left (with asm).. Should be =, because when the compiler create the VST or EXE, should interpretate the primitive in the same code of ASM component or not?

as you can see, it does....

Well. So changing from code to asm will not make nothing better, true only if i can "fix" directly ASM.

But, you have tested your schematic on a d.a.w. ?
On my d.a.w. phase not changed...
