oeksound spiff
8.5Great
An adaptive transient processor that detects transients via spectral analysis and cuts or boosts them with time- and frequency-specific controls.
Editorial analysis
The key difference
Both come from oeksound and share the same adaptive, crossover-free DNA, which is exactly why producers line them up against each other. But they hunt different prey: soothe2 chases resonances and harshness across the frequency spectrum, while spiff targets transients in time. They are siblings, not rivals.
Decisive signal
The decisive split is what each tool listens for. soothe2 is a dynamic resonance suppressor: it watches for frequencies that spike and ring, then ducks them so a source loses harshness without losing tone. spiff is an adaptive transient processor: it watches for the attack itself, the click of a consonant or the stab of a pick, and cuts or boosts that moment with frequency-aware precision. One works on sustained tonal problems, the other on the leading edge of a hit. That axis, resonance versus transient, is the whole decision.
Choose soothe2 if
Choose soothe2 if harshness and ringing resonances are your recurring problem and you want a transparent, near-invisible fix you will reach for on almost every source.
Open plugin file →Choose oeksound spiff if
Choose spiff if you regularly fight clicky consonants, pick attack, or brittle cymbal transients and need surgical, crossover-free control over the attack itself.

Which should you buy?
soothe2 is the broader, more essential tool and earns its slightly higher 8.8 score by solving a problem nearly every mix has, harsh resonances on vocals, guitars, cymbals and full masters. spiff scores 8.5 and is a sharper specialist: outstanding at clicky consonants and brittle attacks, but a session-by-session reach rather than a staple, which makes its premium price harder to justify. Buy soothe2 (or its successor soothe3) as a mainstay; add spiff only when transients are a recurring headache.

Quick reference
soothe2 vs oeksound spiff: FAQ
What is the difference between soothe2 and spiff?
soothe2 suppresses resonances and harshness, sustained tonal frequencies that spike and ring, while spiff shapes transients, the short attack moments like clicks and pick stabs. Both are adaptive and crossover-free, but they target opposite problems, so many engineers own and use both.
Do I need both soothe2 and spiff, or just one?
For most mixes, soothe2 is the higher priority because harsh resonances are almost universal. Add spiff only if you routinely deal with unruly transients like clicky vocals or stabbing acoustic guitars, since it is a specialist you will reach for a handful of times per project rather than on every channel.
Which is better value, soothe2 or spiff?
soothe2 tends to be the safer buy because its versatility spreads the cost across nearly every session, whereas spiff carries a premium price for a narrow, one-job scope. Note that soothe2 has been superseded by soothe3, so check current pricing there, and take advantage of spiff's 20-day trial to confirm it solves a real problem before committing.
