hi,is there an available emulations/algorithms for tube emulation, vinyl emulation, audio output transformers i.e. magnaquest, sowther etc for sigma studio? thank you.
No, I have not seen anyone do this.
I suppose you could purposely connect the serial input with poor signal integrity to generate some random clicks like a record, then use the pitch change cell to simulate wow and flutter. I am joking...
But seriously, we do have some soft clip cells that may be able to be manipulated to sound like a transformer, or tube, being overdriven. But a more true approach using a model has not been done.
It is an interesting question and perhaps someone else might chime in with some suggestions.
There are a handful of customers using SigmaDSP processors in stomp boxes and other effects boxes. That code is, obviously, proprietary. However, people have build some amazing sounding things. We also have available SigmaStudio for SHARC, and that family is very popular for audio effects.
hello Dave, hello Ken
yeah i had seen these on some "FX" processors and VST plugins on some DAWs, What i really had in mind was to replicate the transfer function of a tube or a class A power amplifier into an algorithm, Bob Carver during the "Stereophile Challenge" was able to build an amplifier, modded the transfer function to make it sound like a very expensive amp. During the ABX testing the golden ear audiophiles wasn't able to tell the difference between the amps, one expensive and the one that was moded. thank you for your reply
This has been a very active area of research for many years (e.g. Line 6). As the number of companies manufacturing tube shrinks, amplifier manufacturers want a way to sell entry level solid state amplifiers that sound vintage. Also, a lot of DSP grad students play guitar ;-) There are a lot of papers out there. Search the web, and especially look at the Audio Engineering Society Journal and conference papers.
yes after some research I think I had an idea what would be the algorithm block would look like =) an array of two control knob each for the 2nd, 3rd, 4th, 5th, 6th, 7th, 8th thd generator algorithm that will be added to the original signal one knob will control the % thd added and the other is for phase control. it would be nice if you can have a McIntosh sounding amp then switch to an Accuphase with a touch of a button=) it would be a good joke for those audiophile critics ha ha ha
Coincidentally, there are some excellent papers on tube emulation in the AES journal this month. Take a look if you can.
