A gift from The Lake.
Altar is a FREE, open-source guitar amplifier with a feature-set you would only expect to find in a $200 product.
Latest version: 0.3b (Beta)

-- v0.3b --
Core DSP Rewrite:
- Added DC Blocking Filters
- Replaced Tone Stack module with multiple higher quality modules.
- Added alternative waveshaping model for Drive mode.
The DSP should now respond more like a real amp, with less "flubby" distortion and a fuller, rounder overall frequency response. The DC Blocking Filter will also significantly reduce the low-end "gurgling" that was present in earlier versions, especially on palm-mutes.
- Swapped Pre & Post Process Compressors with HISE Defaults.
- Swapped Pre & Post Graphic EQ's with HISE Parametric EQs.
- Added Gain Reduction VU for Compressors.
- Adjusted CPU Usage Meter to more accurate reflect global bottlenecking.
- Added DC Block to Output Limiter.
- Added Inter-Sample Peak Fix (Simple Gain).
- Fixed some NAM-related UI issues.
