Difference between Spectrum and Frequency effects??

[crazyfiltertweaker]

If use a effect which is frequency selective I use it for a specific frequency range. But if I use a spectrum effect, it sounds completely different! Why? It has the same behaviour: as higher the spectrum, as higher the frequency, so why sound spectrum effects completly different?

there is no specific answer to this because 'a effect which is frequency selective' and 'a spectrum effect' are completely nonspecific terms. if you have specific effects in mind, it might be easier to answer, but at present it might just be the effects you've tried dont do what you think they do.

as example a spectral delay/frequency selective delay.>>>totally different sound!

or phase vocoder effects as example INA GRM Tools! You cant compare it with frequency selective effects.

which spectral delay, though? thats nearly as nonspecific as your original question.


Most of the spectral delays Im familiar delay multiple 'bands' separately (cf Spectral Delay, Spectron, etc) which is clearly going to sound different depending if the bands have indpendent delay times.

Im not even sure what you mean by 'frequency selective delay', btw. One with LPF/HPF filtering on the input?

what is a spectral delay?

[whyterabbyt]

BTW This isnt a Music Theory question in any way.

Maybe the difference is between ONE and several frequency bands?

So, for example, the MMultiBandDelay by Meldaproduction would be some kind of "Spectral Delay"?

what is a spectral delay?

Generally spectral effects have been 'split' (by FFTs) into separate bands (usually in the hundreds or thousands of bands), the bands processed individually or in groups, and then the signal recomposed (by inverse FFTs) into audio again.

no, it is a multi frequency band delay, not a spectral delay.

and that is the question, these two sound completelty different, but why?

which spectral delay, though?

as example grm tools delay or the native instruments spectral delay.

No, it wouldnt. Its still operating in the time domain. Mutiple bands arent what defines spectral processing, frequency domain processing is.

Well as I understand it from the NI website TrickyLoops is right. The NI spectral delay just has more bands. And it has modulation, don't know whether the Melda plug has that too.

So I think you are just talking about multiband effects with different technical specs, including number of bands, which make the differences in sound.

Well, the NI Spektral Delay has 1024 bands, the MMuliBandDelay only a few, so it's a big difference!

If we could split the signal into several hundred bands, maybe it could be called "Spectral Delay"...

So if the answer is so easy, why sounds a Equalizer completely different as example the Iris spectral synth?

[stringtapper]

It all depends of the implementation used in the software but EQs generally employ standard delay-based filter algorithms while most spectral effects use FFT-based processing, which offers more precision in the frequency domain.

Think what you like, it's still not the underlying difference. Your failure to understand the difference doesn't negate it.
