The SPL Attacker micro-plugin employs the same processing technique as the original, and now legendary, SPL Transient Designer. Both rely on SPL’s Differential Envelope Technology that revolutionized dynamic processing with its level-independent methodology.

Working with the Attacker is disarmingly simple: All attack events can be amplified regardless of their signal level. However, don’t let this plugin’s simplicity fool you — the possibilities for studio and live applications are seemingly endless.

Traditionally, EQ has been used to separate instruments in a mix. By focusing on the initial transient instead of specific frequencies, the SPL Attacker amplifies just the attack curves of a sound event. This allows instruments to be mixed at lower levels, which opens up space in the mix while the relationship between tracks is preserved.

Emphasize the attack of a kick drum or a loop to increase the power and presence in the mix. Adjust the apparent “distance” of the microphone by simply varying the ATTACK values. Increase the attack of guitar sounds for that in-your-face tone.

The Analog Code
“You have cracked the analog code!” That was the response from a hardware developer during listening tests of SPL’s plugin technology. The phrase quickly became associated with SPL to such a degree that the company decided it was the perfect name for their digital product line. And thus, SPL’s Analog Code brand was born.

SPL hardware products can be found in the world’s most renowned facilities, and have become a staple for audio professionals ranging from home studio owners to top mastering engineers. With the growth of computer based audio systems, the need for the SPL sound in the form of a plugin has also grown. With Analog Code plugins, that coveted SPL sound can now be right inside your DAW.

    SPL delivers world class quality
    by UnbalancedBeats
    I find it perfect for adding punch to kicks, snares, hihats and other percussive elements in the mix. Funcionality is limited compared to its big brother but is free.
