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.

Nulltrack! It's null when you start and a track when you finish! Nulltrack is a tracker and digital audio workstation app for your phone. A different way to make music inspired by LSDJ and the Dirtywave M8. Features: AUv3 plugin support - bring your external synths and effects into your track! Two built-in synthesizers -- A versatile two-oscillator Basic Synth and a feature-rich Bass Synth. A built-in sampler -- record your own samples with your phone's microphone, load your own, or use the built-in samples, set loop points, slice, reverse, etc. Modulation -- Modulate nearly anything with LFOs, AHD / ADSR / drum envelopes, velocity, randomness, and key tracking, filter, panning, and more. Mixing Features -- track faders with solo and mute, 13 built-in effects, sidechain compression Sends -- share effects between tracks Customize your swing/playback with groove tables! Lock your patterns to a built-in scale! ...and much more! New to trackers? They're a fast, grid-based way to write music. Try it out! No ads, no subscription, no in-app-purchases, and no account needed.

Verdict

The call

The clearest difference is price: Nulltrack at $7.99 against SGA Eclipse's $24.99. Nulltrack also leads on update cadence (every 9 days vs every 6 months). SGA Eclipse's advantage is device support (3 vs 1) and iOS requirement (15.8 vs 17.0). On ads, in-app purchases and monetization model there is nothing between them.
