SPL revolutionized the recording and live sound industries with their introduction of the Transient Designer. For the first time ever you could control dynamics, independent of the levels!

The analog Transient Designer and its plugin counterpart both use SPL's Differential Envelope Technology for just that.

Unlike compressors, the SPL Transient Designer can transparently shape the attack and sustain characteristics of any sound, no matter its level - super loud or whisper quiet, constant or fluctuating

No more fiddling with Threshold, Hold Times, etc.

In fact, Transient Designer uses only two primary controls - Attack and Sustain - to process dynamics.

Make trap drums slam harder. Tame a ringing snare drum. Reduce excessive cymbal bleed into tom mics. Increase sustain on soaring guitar solos. All with the twist of just two knobs.

More Powerful and Versatile - TD Plus!

In Transient Designer Plus, the Output Gain control is placed before a new soft-clip limiter in the audio path. Say goodbye to lowering the fader for your track every time you boost the Attack or Sustain knob - the built-in limiter prevents digital clipping. And it is latency-free! German engineering at its best.

Parallel processing has been integrated. And Transient Designer Plus also adds powerful side chains, internal and external!


VENUE AAX format is no longer available for this product. As of May 24th, 2018, the VENUE AAX format will not be part of the license. Current VENUE users don’t need to worry, everything that currently works will continue to do so. Only further development and support will end.

  • SPL Transient Design Plus Nominated for 2017 TEC Award

    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!
