About

Chorus D

This audio unit effect emulates a classic chorus stomp-box with a unique, subtle sound. It offers a wider stereo image and thicker sound without the typical pitch-wavy artifacts. Its simplified interface provides a range of tasteful tones.

Highlights
  • Subtle stereo pitch-shifting
  • Constant pitch-shift amounts
  • Stereo image widening
  • Sound thickening
  • Six tasteful presets
  • Unique sound profile

Chorus D is an audio unit effect inspired by a well-loved classic chorus stomp-box. HOW IS IT DIFFERENT FROM OTHER CHORUS EFFECTS? It's more subtle. It has a stereo pair of pitch-shifters, one shifts up and the other down. Every few seconds, the two pitch shifters trade places: the high one goes low and the low one goes high. Unlike most other chorus effects, the pitch-shift amounts stay constant rather than oscillating up and down. For that reason, you don't hear the wavy pitch sound that other chorus effects make. At low settings, you can put it on a track to widen the stereo image or thicken up the sound and listeners may not be able to identify that they are hearing a chorus effect. WHY ONLY SIX BUTTONS? The original hardware that inspired this design had only four buttons and four presets, one for each button.* The simplicity of the controls is one of the reasons the effect was so well-liked: all four presets sounded great. With six buttons you get tones ranging from very subtle to clearly audible, and all of them are tasteful and useful. This effect makes only one type of sound but it's a unique sound that you don't get from other chorus effects. IS THIS AN EXACT CIRCUIT MODEL OF THE ORIGINAL HARDWARE EFFECT? No. We listened to the original and studied its design but then we built an effect to please our own ears. It sounds similar to the original but the design is unique. ************************************ Note: this is an audio unit plugin. It does not process audio as a standalone app. *Later on customers figured out that they could get some other settings by pressing two buttons simultaneously or forcing all the buttons off. We are using six buttons to get wider variety of sounds rather than expecting customers to discover those secret features of the original hardware.

About

SGA Eclipse

This app offers authentic analog amplifier sounds for digital audio workstations. It simulates six different analog circuits, including vacuum tubes and transistors, to provide a range of saturation and distortion effects. It can be used as a standalone effect or in conjunction with other plugins to create full amp simulations.

Highlights
  • Authentic analog sound simulation
  • Six distinct analog circuits
  • Vacuum tube and transistor emulation
  • Variable bias and feedback controls
  • Automatic 4x oversampling
  • AUv3 effect plugin

Eclipse brings the authentic sound of six analog push-pull circuits to your DAW. Each circuit derives its unique sonic character from a different active element: - 6L6 beam tetrode – Power tube commonly found in US audio power amplifiers in class AB push-pull configuration. - EL34 pentode – Power tube found, operating in class AB push-pull configuration, in audio power amplifiers and many European guitar amplifiers. - EL84 pentode – Power tube found in many European audio equipment, gainer than the usual pentode, operated in push-pull class AB configuration for maximum power output. - pair of complementary N- and P- MOS transistors found in CD4007 - 2N5457 and BF244B JFET transistors in mu-amplifier/SRPP/totem pole amplifier configuration found in some boutique guitar gear, including Shattered Glass Audio. To achieve the most authentic analog sound, each circuit is simulated in real time using Shattered Glass Audio’s state-of-the-art circuit simulator. Eclipse can be used to deliver anything from subtle saturation to ripping distortion, as well as in a tandem with a preamp simulation plug-in, such as our own Phoenix 2, and a speaker cabinet emulation plug-in to create a full amp. Key features: - Authentic analog sound through real-time high-performance circuit simulation. - Three vacuum tube push-pull configurations (fronted by a long-tailed phase splitter using 12AX7 triodes) featuring 6L6, EL34, and EL84 power tubes. - A complementary N- and P- MOS transistors in push-pull configuration. - Two mu-amplifiers featuring JFET transistors 2N5457 and BF244B. - Variable bias and feedback for each circuit for different saturation “flavors”. - AGC and parallel processing. - Automatic 4x oversampling. Eclipse is primarily an AUv3 effect. To use Eclipse as a plug-in, you will need an AUv3 compatible host such as Garageband, AUM, etc. Eclipse application is there to provide a user manual and a chance to use Eclipse with the microphone input. You can try Eclipse on a macOS or Windows based, machine by downloading the demo version of the plug-in (VST3, AUv2, AAX) from our website https://www.shatteredglassaudio.com and running it in a DAW of your choice. Sonically speaking there are no differences between the iOS and macOS/Windows versions of Eclipse.
