B
Bypass
B takes the plug-in out of the signal - smoothly, without clicks.
Engineer Factory · The DAW
Record, edit, mix, export
A complete DAW for Windows: a stable audio engine, VST3 support, 17 built-in plug-ins and the AI Engineer for mixing and mastering. Using it requires a valid licence.
Version 2.1.0 · 83 MB · Windows 10 & 11, 64-bit
Downloading and using it requires an account with a valid licence.
Audio engine
Stable, even when a plug-in is not
The audio engine runs separately from the interface. If a plug-in crashes, the window and your unsaved project stay open - the engine restarts and tells you which plug-in caused it.
- Windows Audio (WASAPI) including a low-latency mode, plus DirectSound
- Choose the device, sample rate, buffer size and inputs
- Latency display and test tone
- Keeps running when you switch audio devices
Plug-in chain
Every plug-in in the order it processes
Each track shows its plug-ins as a chain, in processing order. The 17 built-in EF plug-ins share one clear, consistent design.
- Reorder plug-ins by drag & drop
- Insert a plug-in anywhere in the chain
- Find plug-ins by search, category, vendor, favourites or recently used
- Copy, paste, duplicate or reset a plug-in from its slot menu
Four controls on every slot
Alt + B
Switch off
Alt+click on B switches the plug-in off completely: it uses no CPU, and its settings are kept.
N
Normalize
N matches the loudness before and after the plug-in, so you hear what it really does - not just that it is louder.
0–100 %
Signal fader
Blend dry and wet from 0 to 100 % - in time even with plug-ins that add latency, and automatable.
Side-chain
Side-chain between tracks
Let one track control a plug-in on another - the kick drives the compressor on the bass, for example. The source only controls the plug-in; you do not hear it through the key.
- Side-chain input on the EF Compressor, EF Gate and EF De-Esser
- Works with the side-chain inputs of VST3 plug-ins
- Taken pre or post fader
- Protection against feedback loops
- An overview of all side-chain routings, and a label such as “SC: Kick” in the chain and the mixer
Everything stays in time
Latency compensation works automatically on every signal path - inserts, sends, buses and side-chains. For recording there is a low-latency monitoring mode.
A missing plug-in never blocks your project
Missing, unlicensed or faulty plug-ins are skipped - no pop-ups, no crash - and your project still opens. A small status shows which plug-ins are unavailable, with “Try again”.
