Overview

Threshold-Independent Dynamics Processing
A compressor is a threshold-dependent device, meaning it only reduces the level of a signal when it breaches the compressor's threshold level. Unfortunately, if you wanted to take the edge off all the peaks of a jazz drummer's dynamic snare recording, a compressor would apply more gain reduction to loud transients than quiet transients. However, thanks to SPL's Differential Envelope Technology, you can consistently sculpt the volume envelope of transients, regardless of their peak level.

Extensive Control With Just Two Knobs
Instead of attempting to dial in a compressor's threshold, hold time, and various other settings, all you need to focus on is the SPL Transient Designer Plus's Attack and Sustain knobs. The Attack knob amplifies or attenuates the initial part of transients, while the Sustain knob amplifies or attenuates the tail-end of transients. There's also a Sidechain Filter that rejects parts of a signal to prevent them from being processed, allowing you to target specific components of a drum bus—like the kick drum.

Mixing Drums Has Never Been Easier
Make trap drums slam harder, tame ringing snare drums, reduce excessive cymbal bleed into tom mics, and increase sustain on soaring guitar solos. Apply processing in parallel using the Parallel Mix knob to emphasize transients and then blend in the original signal. SPL Transient Designer Plus is also latency-free and includes a built-in soft clip limiter that reduces digital clipping. Regardless of the genre of music you produce, this plugin will help you streamline your mixing workflow.

Features

  • SPL's Differential Envelope Technology.
  • Separate controls for Attack and Sustain.
  • Process stereo track channels independently.
  • A soft clip limiter that helps prevent digital clipping.
  • Parallel processing functionality.
  • Internal and external sidechain.

    SPL Transient Design Plus Nominated for 2017 TEC Award

    Champagne corks were popping at SPL headquarters in Niederkruechten, Germany, as well as here at Plugin Alliance, when we recently learned that the SPL Transient Designer Plus plugin was nominated for the 2017 TEC Award in the category of Sound Processing Software (DYNAMICS/EQ/UTILITIES).

    The original Transient Designer was one of the most popular plugins in the Plugin Alliance, and the Plus version, released early this year, is not only a major advance in realism, but provides an array of new features like a wet/dry mix control and side chain.

    Congratulations to Alliance member SPL for this great and well deserved honor. If you haven't checked out the new Transient Designer Plus, find out for yourself why the TEC committee was so impressed by downloading a free, full function 14-day demo today, and stay tuned for more info on how you can cast your vote for the TD Plus!
