About virtuAMP - NemPosted: Jul 4th, 2007 - 3:10:16 pm

virtuAMP is an open source real time virtual guitar amplifier for your home computer. virtuAMP provides an intuitive interface for customizing your sound through a virtual pedalboard, which behaves as your existing guitar rig does, allowing you to place effect pedals, connect them using cables and control their sound using their controls. Your guitar connects directly to virtuAMP through your sound card's line in, making virtuAMP a good substitute for a practice amplifier.



Audio Samples:

Each of these audio samples were captured by virtuAMP from my guitar (a Fender Stratocaster) connected directly to my sound card. No post processing was added, only Audacity was used to convert the .wav file to .mp3.

Great stuff man, pretty user-friendly too lazy

Being nit-picky I know, but according to the W3C validator, this page doesn't actually validate. Something to do with your nested list, I think. The nested list probably has to be wrapped in an <li> element.

Thanks, fixed. apple

We need some sort of conversion or special jack lead for this?
coz my standard guitar to amp lead wont go into my sound card (Durr :P)

I know my mate has this wierd thing you put on the end of your jack to turn it into a 2.5/3.5mm jack instead which would make it fit, but i've no idea where to buy one, how'd you plug your guitar in nem?

Loving all your tools btw, just registerd.theforce

I want to test that program with my guitar :D so nice :P

NICE!!! This is one of best RTAS i ever tryed!!! Bit problem is latency! Is there any way to fix that?headphones

7. NemPosted: Nov 18th, 2007 - 3:07:04 pm
The latency is ultimately determined by the speed of your computer and the quality of your audio card. In order to reduce the latency, you may try playing around with the settings in the Audio menu. Specifically, try increasing the Buffer Denominator, this is one over the target latency in seconds. You may also be able to achieve a higher denominator by changing your Driver.


8. LoCoSerRuPosted: Nov 19th, 2007 - 10:23:48 am
Tnx!!! Its better now! yeahbaby But did u considered WDM streaming? i had good experience with it i the past, no latency at all!
I have
AMD Athlon 64X2 dual core 4200+
2GB of Kingston RAM
Biostar GF 7900 GS theforce
Biostar TForce m570 motherboard( i use integrated soundcard)
Realtec Audio drivers(newest)
And Ibanez RG (Japaneese) with Rolland custom humbuckers and 0.10 strings.

Hi Nem,

love your virtuAMP. I am working on a program similar to yours. I am using ASIO audio drivers for even lower latency than in virtuAMP. So my question is what literature did you use to write a functions like reverb, distortion, flanger...? Is there some site with math formulas what to use?

Thx in advance

10. NemPosted: Apr 6th, 2008 - 12:06:46 pm
Harmony Central has some good articles explaining various common effects. Other than that, I just read up on how each effect is typically implemented (in hardware) and tried to replicate it.

The source code for virtuAMP is also available, you may want to look at it.

I'm pretty sure this isn't included, but maybe you could include a metronome or click track pedal in the next version. It'd be a nice addition for rythem and what-not.

12. NemPosted: May 23rd, 2008 - 4:33:14 pm
Will do. free

Added to version 1.2.1. apple

it would be great if this software was available as a VST plugin

15. CapnJackPosted: Jan 13th, 2009 - 12:07:03 pm
Have you ever considered adding ASIO driver support?
