ToneBoosters has announced the release an innovative bass synthesizer plugin featuring 3 analog-simulated, voltage-controlled oscillators with a large variety of waveform algorithms, continuous pulse-width modulation (PWM), Frequency Modulation (FM) and oscillator hard sync, complemented by a voltage-controlled noise synthesizer, parameter modulation a re-designed non-linear voltage controlled filter.

Lowtone is said to be the world’s first bass synthesizer featuring loudness-domain harmonic synthesis, creating deeper, more consistent and production-ready bass sounds compared to conventional synthesizers operating in the (linear) amplitude domain.

Loudness perception of tones and harmonics is known to be highly non-linear and intricately frequency and level dependent. Equal loudness contours, or Fletcher-Munson curves demonstrate this drastic effect for sine tones, which is especially relevant for low frequencies.

The loudness of a synthesizer bass note, and all its individual harmonics, will therefore depend strongly on what note you play on your synth’s keyboard.

To overcome the resulting inconsistencies in loudness and timbre, TB Lowtone features innovative, loudness-domain synthesis algorithms that adjust each harmonic individually to compensate for loudness deviations across frequency.

Housed in a fully resizable user interface, Lowtone includes large number of cross-platform compatible presets, and a preset browser that allows for sorting, searching, and categorization. A smart randomizer generates new patches with a single click, and it can learn from the patches you have already created to generate new, personalized patches.

Available in VST/VST3, AU and AAX plugin formats and as standalone software for Windows and macOS, Lowtone is priced 24 EUR. The iOS/iPadOS version (AUv3/IAA/Standalone) is priced $9.99 USD at the App Store.
