Acon Digital, a prominent developer of high-quality audio software, has officially released Multiply 2, a significant upgrade to its highly acclaimed free chorus effect plugin. The update, made available earlier today, immediately garnered attention from the music production community, reinforcing Multiply’s position as a staple in digital audio workstations (DAWs) worldwide. This release marks a pivotal moment for producers seeking professional-grade modulation effects without financial barriers, further democratizing access to sophisticated sound design tools.
Multiply has long been celebrated for its exceptional sonic character, often cited by industry experts and users alike as one of the finest free chorus plugins available. Its previous iteration earned a distinguished spot in numerous "best free chorus plugins" roundups, lauded for its ability to imbue electric pianos, guitars, and lead vocals with a rich, expansive quality without introducing artificiality or smearing. The advent of Multiply 2 builds upon this strong foundation, introducing a suite of enhancements designed to elevate its performance, usability, and versatility.
The Enduring Significance of Chorus Effects in Music Production
To fully appreciate the impact of Multiply 2, it is essential to understand the fundamental role of chorus effects in audio production. A chorus effect is a modulation effect that simulates the sound of multiple voices or instruments playing the same part simultaneously. This is achieved by creating several delayed and pitch-shifted copies of an incoming audio signal, which are then mixed back with the original. The subtle variations in timing and pitch between these copies create a thicker, richer, and wider sound, mimicking the natural imperfections and phase differences inherent when multiple performers play together.
Historically, chorus effects gained prominence with hardware units in the 1970s and 80s, becoming an iconic sound on synthesizers like the Roland Juno series, electric pianos such as the Rhodes and Wurlitzer, and guitars. Its application quickly expanded to vocals, strings, and pads, becoming an indispensable tool for adding depth, movement, and presence to various elements within a mix. The transition to digital audio workstations in the late 20th and early 21st centuries saw the proliferation of software-based chorus plugins, offering greater flexibility and affordability. However, the challenge has always been to replicate the organic warmth and complexity of analog chorus units while avoiding undesirable digital artifacts like metallic ringing or phase issues. Acon Digital’s Multiply has consistently met this challenge, and Multiply 2 endeavors to set a new standard for free software in this category.
Acon Digital’s Commitment to Quality and Accessibility
Acon Digital, known for its meticulously crafted audio processing tools such as the highly regarded Equalize 2, Restoration Suite, and DeVerberate, has established itself as a developer committed to both innovation and sonic integrity. While the company offers a comprehensive range of commercial products catering to professional audio engineers and sound designers, its continued investment in high-quality free plugins like Multiply underscores a broader commitment to the music production community. This strategy not only serves to introduce new users to the Acon Digital ecosystem but also provides invaluable tools that empower aspiring and established producers regardless of their budget.
The original Multiply plugin, released years prior, quickly garnered a loyal following due to its pristine sound and intuitive controls. Its reputation grew through word-of-mouth and consistent high ratings in comparative reviews, demonstrating that "free" does not equate to "compromised quality." Acon Digital’s decision to dedicate significant resources to a major update for a free product speaks volumes about their philosophy of delivering exceptional value across their entire product portfolio.
Unveiling Multiply 2: Key Enhancements and Technical Innovations
Multiply 2 arrives with a host of significant improvements, directly addressing user feedback and leveraging advancements in audio processing technology. These enhancements are primarily focused on refining the user experience, expanding sonic possibilities, and maintaining its celebrated sound quality.
1. Redesigned User Interface: The most immediate and noticeable change in Multiply 2 is its completely redesigned user interface. Modern plugin design emphasizes clarity, ease of navigation, and visual feedback, and Acon Digital has delivered on all fronts. The new interface is sleek, intuitive, and highly functional, making it easier than ever for users to dial in desired effects or explore new sonic territories. This visual overhaul is not merely aesthetic; it streamlines the workflow, allowing producers to quickly access parameters for chorus, widening, and advanced sound design, thus enhancing creative efficiency. A well-designed interface is crucial, especially for complex modulation effects, as it allows users to understand and manipulate intricate parameters without getting lost in menus, fostering a more fluid and enjoyable creative process.
2. Expanded Preset Library: Accompanying the new interface are 80 new factory presets. Presets are invaluable tools for producers, offering immediate starting points, demonstrating the plugin’s capabilities across various instruments and genres, and serving as inspiration for unique sound designs. These new presets are curated to showcase the full spectrum of Multiply 2’s potential, from subtle thickening and classic chorus sounds to extreme stereo widening and experimental modulated echo effects. This expanded library caters to diverse production needs, making it easier for users to quickly find the right sound or adapt a preset to their specific project requirements, whether they are working on vocals, guitars, synthesizers, or drums.

3. Advanced Core Technology: The Phase-Randomizing Filter: At the heart of Multiply 2’s acclaimed sound quality lies its sophisticated phase-randomizing filter. This innovative algorithm is meticulously applied to each of the simulated voices, a critical design choice aimed at circumventing the common pitfalls associated with simpler chorus effects. Unlike many conventional chorus units that can inadvertently introduce undesirable metallic comb-filtering artifacts, resulting in a thin or hollow sonic character, Multiply 2’s approach ensures a consistently lush, ‘mellow,’ and organic sound. This technical distinction is paramount for producers seeking to add depth and width to their audio without compromising tonal integrity or introducing harsh resonances, thereby preserving the natural character of instruments and vocals while imparting a rich, enveloping modulation. This deep technical approach is what separates Multiply from many other free and even some commercial alternatives.
4. Flexible Voice Modulation: The plugin is capable of simulating up to six additional voices, each with independent pitch and loudness modulation. This level of granular control allows for an extraordinary range of effects. At subtle settings, Multiply 2 excels at natural thickening, adding a gentle shimmer or depth that enriches the source material without drawing undue attention. For more adventurous sound designers, pushing the parameters to extreme settings can transform Multiply 2 into a powerful tool for creating wide, unstable, and highly modulated effects, perfect for experimental electronic music, expansive pads, or unique vocal textures. The interplay between pitch and loudness modulation is key to achieving these varied results, from subtle stereo enhancement to dramatic sonic transformations.
5. Integrated Five-Band Equalizer for Effect Signal Shaping: A particularly powerful feature introduced or enhanced in Multiply 2 is the built-in five-band equalizer. Crucially, this EQ operates only on the wet (effect) signal, leaving the dry (original) sound untouched. This precise control over the chorused signal offers immense creative and corrective possibilities. For instance, a producer might want to add a bright, airy chorus to a guitar but prevent the low-mids from becoming muddy; the EQ allows them to cut the low-end of the chorused signal without affecting the core guitar tone. Similarly, one could boost the high frequencies of the effect to add more shimmer or roll off harshness, ensuring the chorus sits perfectly within the mix rather than clouding the entire soundscape. This independent EQ control is a hallmark of professional-grade effects, providing surgical precision in sound sculpting.
6. Pre-Delay Section for Diffuse Modulation and Sound Design: The integrated pre-delay section further expands Multiply 2’s capabilities beyond traditional chorus effects. By introducing a delay before the chorus modulation begins, the plugin can venture into diffuse, modulated echo-style effects. This feature is particularly valuable for sound design, enabling the creation of lush, evolving pads, ethereal atmospheres, or unique spatializing delays that add a sense of movement and depth to any sound. The ability to manipulate pre-delay opens up avenues for crafting complex ambient textures and rhythmic modulations, pushing Multiply 2 into the realm of a versatile sound design tool rather than just a simple modulation effect.
