After my guitar amp project had a poor showing in the KVRAudio DC2013, I started reading more material on guitar amps and cabinets. I realized real amps produce a significant amount of high frequency harmonics and by themselves are not very pleasant to listen too. A guitar cabinet has a reduced frequency range and thus helps cut out those high frequencies.
So I started trying to simulate a guitar cabinet in SynthMaker. My simple approach was to use a combination of filters that would mimic the frequency response curve of the cabinet/speaker combinations. After finding very good reference material, it appeared others were using simple combinations of low and high pass filters. On one blog a person was experimenting with using a combination of low/high self and a notch filter so I thought I would start with that.
This is the result of that work. I included a frequency readout so you could adjust the response to your own taste. I also added a section that acts like the microphone adjustment that other cabinet sims have. However, my version only pans and adjusts the volume level using the X-Y pad created by oddson, Angular Momentum, and infusion, and a simple mic graphic. I have attached a revised version of my guitar amp as well.
When I tried it out with my revised guitar amp, it made a significant difference, at least on my Win XP, Sony Music Studio 7 DAW. It softened the high frequencies, stopped some of the squeals from the guitar amp.
It still needs more work (need to scale the frequency display appropriately depending on the selected low and high frequency range and continue experimenting with filter combinations). Below are some screen captures and osm if you want to play around with it. I would appreciate any constructive comments.
