zplane built the algorithm that quietly underpins pitch correction and time-stretching in half the DAWs on the market. Ableton, Cubase, Pro Tools, Reaper, FL Studio, Studio One—ÉLASTIQUE is everywhere, just never with zplane’s name on the label. TIMBRE changes that. Launching today, it’s the Berlin company’s first direct-to-user formant manipulation plugin, and whether it earns its place on your insert chain depends entirely on one question: what are you actually trying to do that your current tools can’t?
The concept is straightforward. Formants are the resonant frequencies that give a sound its identity—why a tenor sounds like a tenor regardless of what note he sings, why a violin and a cello playing the same pitch still sound completely different. EQs shape frequency content. Pitch shifters move notes. Neither touches the formant structure in isolation. zplane TIMBRE does exactly that: it shifts the spectral envelope of any source independently of pitch, with a ±36 semitone range across two independently adjustable frequency bands separated by an adjustable crossover.
What TIMBRE Actually Does (And What It Doesn’t)
Dual-band formant shifting is the core of the plugin. Each band can be set independently—push the lows down to fatten a vocal chest register while leaving the upper harmonics alone, or dial in a crossover that targets only the body of a snare. A linked mode collapses both bands to a single knob for producers who want the effect without the architecture. Per-band On and Solo switches let you audition each band’s contribution in isolation, which matters when you’re dealing with signals where the crossover point is doing a lot of heavy lifting.
The more unusual element is the Carrier section. This lets you strip out the original signal’s waveform—the carrier—while retaining its modulation envelope, then replace it with either a built-in white-noise source or an external sidechain. Feed in white noise and vocals turn into whispered textures or breathy air. Route a sidechain signal in and you’ve built a formant vocoder without routing three separate plugins. That’s genuinely new territory for a plugin this focused, and it’s where zplane TIMBRE separates itself from the pitch-with-formant-lock tools already sitting in most producers’ chains.
The Resolution control adjusts processing granularity—essentially the level of spectral detail the algorithm works with. Push it high and you get more precise, artefact-resistant results; pull it back and the processing becomes heavier and more characterful. A Dry/Wet knob handles parallel blending without needing to set up a separate return channel.
The Elephant in the Room: 23ms Latency
Real-time formant processing at this level of quality doesn’t come free. zplane TIMBRE runs at 23ms of latency at 44.1kHz—roughly half the typical real-time buffer of a lot of live performance setups. For mixing, that’s a non-issue. For tracking a vocalist who’s singing against a headphone mix with the plugin on the bus? That’s going to be audible delay, and there’s no low-latency mode to fall back on. If you’re using TIMBRE as a live performance tool or a tracking effect, factor that in. It’s not a dealbreaker, but it’s the kind of friction zplane’s own ÉLASTIQUE Pitch 2 review here on ANR touched on years ago—real-time audio quality and minimal latency pull against each other, and something has to give.
For context, we covered zplane’s PEEL STEMS 2 in July, where 245ms of stem-separation latency was the headline limitation even after a 49% improvement. TIMBRE’s 23ms is a completely different class of problem, but the pattern holds: zplane’s algorithms prioritise quality over raw speed, and that’s a conscious design choice worth knowing going in.
Pricing and Availability
zplane TIMBRE is available now. The standard price is €79, with a 33% introductory discount running through the end of September, bringing it to €53. Plugin format support covers VST3, AU, and AAX—the full DAW compatibility spread.
