EFU-1 Echo Freeze Unit is a free delay and echo VST plugin developed by WOK. Compatible OS(s): Windows.
EFU-1 is more than another delay plug-in. Besides all the basic functions (host sync or milliseconds, digital/tape/analog sound, modulation) it features a distinctive freeze function – like some famous hardware delay units, the delay buffer can act like a sampler. Up to 4/1 bars of input signal can be recorded (or “frozen”) and continuously played back at a selectable speed – even reverse.
But EFU-1 is more flexible than hardware devices: while a frozen audio segment is played back, the delay unit remains useable – even at a different delay time / sync divider. Also to hold and freeze a signal it is possible to first choose “record” and then send audio to the plug-in, or you continuously play thru the delay and if the “last loop” was interesting, you hit “Record” to freeze it.
And while the recorded phrase is played back – even reverse, you may continue to play along with it thru the delay at a different time setting. Feedback can be cranked up until nearly endless, and in millisecond mode, the delay time can be changed smoothly from many seconds to very short – producing these famous dub sounds.
The ease of use, low CPU usage and musical functionality make EFU-1 the perfect tool for live mangling your audio.
