take control of your transients

Spiff is an adaptive transient processor that lets you cut or boost transients with great detail. Spiff analyzes the incoming signal and recognizes when and where transients appear adaptively. Its time- and frequency-specific controls let you take charge of your transients, no matter how big or small. Spiff’s unique approach to transients opens up possibilities not usually associated with transient control.

Spiff is really one of a kind. It takes a completely new approach to transient design and I immediately found great uses. I’m actually going to remix a percussion project I’m doing so I can add Spiff. It’s that good.

hear spit? use spiff

Originally Spiff was designed to remove mouth clicks in vocal recordings. Mouth clicks occur when a vocal is recorded close to the microphone and often become an issue when high frequencies are boosted, and compression is added. Use Spiff to save time when editing vocals, voiceovers, and podcasts.

...an intriguing and very modern plug‑in that allows unprecedented levels of manipulation over the transient information in your audio. read review

The best thing about digital recording can sometimes also be the worst. The accurate capturing of transient information can be fatiguing and indeed painful to listen to. Analogue tape used to round the edginess of transients off and make them creamy and lovely to listen to, now Spiff does a similar job (and so much more!), oeksound have another winner on their hands, it's all over my new mixes.

spiff it up

Engaging the boost mode transforms Spiff into a powerful transient enhancer – adding attack to drums and other rhythm material. However, Spiff’s adaptive approach gives you additional control over which transients to boost and in which frequency area. Boost fundamentals on drums without additional boominess or bring any sound to the front of a mix without increasing their RMS level.

It’s another winner from oeksound. A versatile, effective transient processor that you won’t know you need until you try it, and then you won’t be able to go back! read review

cut it out

In addition to mouth clicks, Spiff’s detailed transient recognition offers a number of other mixing solutions: Soften the pick attack of a guitar recording while retaining the top-end shimmer or soften transients over a whole mix, similar to tape saturation. For more extreme applications: make an electric bass sound fretless, or create room mics out of overheads.

During the production and mixing stages of “Gooodbye"(Jason Derulo, David Guetta, Nicki Minaj, Willy William), Spiff allowed me to interact with transient information both creatively and technically, in a totally different way - It’s almost like having a transient "cheat-code”

no bands means no artifacts

Where traditional transient shapers work as compressors and envelope shapers over one or more bands, Spiff approaches transients differently. It analyzes the incoming signal using spectral analysis and applies cuts or boosts using dynamic filters. Spiff does not use any crossovers in the process, which eliminates any possibility of crossover artifacts that can occur in multiband transient processors.
