Contour 1 a Slew Limiter & Function Generator
Joranalogue Audio Design launched Contour 1. Contour 1 brings a fresh approach to this classic circuit. It delivers much-improved performance and control by incorporating modern design techniques. At its most basic, a slew limiter slows down the rate of voltage change in a signal. On Contour 1, the rising and falling rates can be individually set using sliders and CV modulation.
Contour 1 Features
- Analog voltage controlled bidirectional slew limiter.
- Precision circuitry to slew any signal, including pitch CV, accurately.
- Separate rise/fall slope bending with voltage control and compensation for minimal effect on slew time.
- Real-time visual feedback through LEDs on slew time sliders.
- Dedicated gate input in addition to the analog slew input: easily create +10 V attack-release (AR) envelopes, regardless of the gate amplitude.
- Trigger input and push-button: reset the slew core and trigger a one-shot attack-decay (AD) envelope through a single trigger signal.
- Voltage hold gate input ‘freezes’ the slew core. Pause envelopes and LFO modulations, or create pulse-width-sensitive sync sounds at audio rates.
- Impedance-compensated regular and inverted analog outputs.
- Rise and fall status gate outputs.
- Loop switch for variable waveshape temperature-stable VC(LF)O operation. Gate input functions as an oscillation enable input in loop mode.
- Capable of 1 volt/octave tracking over several octaves.
- Wide slew time range: 500 µs to 30 seconds per slope. Audio range switch setting constricts range to ease tuning.
- V/octave trim potentiometer accessible from the front panel.
- Highly multifunctional: slew limiter, envelope generator, envelope follower, (gated) VC(LF)O, frequency divider, slope detector and much more.
- Precision-milled 2 mm anodized aluminum front panel with high-resolution, non-erasable graphics.
- Bullet-proof design: polarised power header and MOSFET protection circuit.
- Includes 16-to-10-pin Eurorack power ribbon cable.
- Premium mounting hardware: black screws, black nylon washers and matching hex key.
- High-quality components and assembly; designed and made in Belgium.
Brainworx bx_limiter True Peak Introductory Sale
bx_limiter TP (True Peak) from Brainworx is a completely new design, crafted to avoid the shortcomings of existing true peak limiters. Use it to confidently hit your loudness targets without leaving behind any distortion-inducing inter-sample peaks, and without compromising on the sound quality of your masters.
Designed from the ground up to be the ideal true peak limiter
Until now, most digital limiters that include a true peak mode have simply added it on as an afterthought. This has left a lot to be desired, with users complaining about unstable low end, compromised stereo imaging, harsh artefacts, and smeared transients. But with the bx_limiter TP, Brainworx has taken a new approach, designing the TP algorithm from scratch to make it perform and sound better than other digital limiters – while also eliminating troublesome inter-sample peaks for even cleaner results.
Use bx_limiter True Peak (Affiliate Link) to confidently hit your loudness targets without leaving behind any distortion-inducing inter-sample peaks, and without compromising on the sound quality of your masters.

Smart, Convincing Loudness Metering and True Peak Brickwall Limiter for Post-Production
Signum Audio release today BUTE Loudness Suite 2 (BUTE-LS2) and BUTE Loudness Analyser 2 (BUTE-LA2), major updates to previous versions, making the mixing and mastering journey even smoother.
BUTE Loudness Suite 2 is a smart, integrated and responsive loudness metering and audio limiting plugin that delivers the tools studios, media, and broadcasting producers need to mix and master professional audio within loudness specifications.
Many producers are moving towards mixing and mastering within loudness specs set internally or by major streaming and broadcasting platforms for quality assurance. By providing metering and limiting functions in the same plugin with smart workflow features to maintain creative flow, BUTE helps optimize the quality of mixes and masters, while avoiding potential distortions downstream.
New in BUTE Loudness Suite 2
The Suite 2 will not overwrite your previous version of BUTE Loudness Suite, so you can have the two plugins running in parallel and not worry about previous projects.
- New integrated limiting functionality within the main user interface allowing configuration of auto-adaptive release, post-gain, and selection Transparent, Natural and Smooth curves presets (not in BUTE-LA2)
- New display settings within the main user interface, including new True Peak/LUFS Metering view, Relative/Absolute Scale, and Max/Live modes
- New Dynamic Range reading as requested by users
- Improved compatibility with a wide range of DAWs (VST / AU / AAX including AudioSuite)
- Auto-syncs to DAW on load-up so plugin engages on launch
- Improved window resizability in full and compact read-out view to optimize screen estate when using multiple programs
- The compact read-out view retains access to limiting controls
- Ability to switch tooltips on and off
- Simplified read-outs for added clarity
- Better responsiveness all-round
- Surround version – auto-detects channel configuration you are using and lets you select the configuration from the drop-down menu in main display to test inputs for up to 7.1.2 Atmos
- Industry-standard (IEC 60268-18) meter bar fallback behaviour or more natural feel
The Loudness Suite 2 includes Bute Limiter 2, Bute Normaliser, and Bute Analyser 2 with a bonus integrated TP Limiting feature. Smart, powerful loudness metering and True Peak Brickwall limiting toolkit for post-production.
