SEOUL, South Korea, Oct. 20, 2026 /PRNewswire/ -- Create and arrange a variety of sounds for a single scene with VARCO Sound, the multitrack AI sound generator.

Multimodal AI company NC AI announced the official release of its generative AI platform, VARCO Sound, on the 20th. Users can easily generate and edit scene-appropriate audio using text, images, and videos. VARCO Sound is designed to help developers and producers who are unfamiliar with sound design bring their creative ideas to life with high-quality soundtracks.

Users can also access the web version of VARCO Sound by signing up on the official website.

NC AI also announced a promotion for VARCO Sound and the AI 3D generator VARCO 3D, running until Nov. 30 following the release. The offer supports continued creation by making AI-based content generation tools more accessible and is available to both new members and existing members who have been using the free version.

Users who make their first purchase during the promotion can receive a 50% discount on the first month of their subscription. Additional bonus points will also be provided, with higher-tier subscriptions receiving even more points. This offer is available once per account for VARCO Sound and VARCO 3D each.

Events will also be held in the official VARCO Discord community. Users who join through the dedicated links provided in each service announcement can enjoy one month of free access to the VARCO 3D Plus plan or the VARCO Sound Lite plan. The first 100 users to join the community will receive the exclusive "VARCO OG" title. In addition, the top five users who share game assets created with VARCO 3D in the community will be selected to receive service credits and titles. Event periods and participation details are available in the Discord announcements for each service

VARCO Sound is a comprehensive platform that allows users to generate and fine-tune audio tracks for content such as games, videos, and animations. Users can describe the desired audio through text or upload an image or video, and the AI analyzes the input to generate scene-appropriate Foley sounds, sound effects, ambient audio, and more.

The tool's most unique feature is its ability to provide separate tracks for each audio source rather than a single audio file. Users can check each track individually, adjust its volume, or replace specific sound effects to further polish the result and better realize their creative vision.

In addition, the "Variation" feature allows users to build on their existing work. Users can upload an original sample to generate variations while preserving its texture and nuance. This substantially reduces the time required to refine ideas and develop prototypes.

The entire generation and editing process can be conducted through natural language using the conversational AI "Sound Agent." A simple description of the desired outcome is analyzed by the AI agent, which automatically applies the appropriate features, lowering the entry barrier for new users.

Furthermore, VARCO Sound comes with an automatic volume mixer feature that prevents sounds from clashing when multiple tracks are played simultaneously. The AI examines and adjusts the volume balance between different tracks so that no sound is too loud or too quiet.

Currently, the maximum length of an audio file that can be generated is 60 seconds, and NC AI plans to continue improving the tool's performance to support video inputs of up to 120 seconds.

NC AI has also released a desktop application and a Unity plugin that allows the tool to seamlessly integrate into the existing workflows of creators. Assets created through the desktop application can be dragged and dropped into other DAWs for immediate use. A personalized library search feature based on natural language and audio will be added in the future to further streamline each user's workflow.

Moreover, the Unity plugin was selected as a Unity Verified Solution, demonstrating its performance and compatibility. The plugin allows game developers to stay within the Unity engine while creating audio tracks using just text and images and immediately apply them to their projects using the built-in editing tools.

NC AI's CEO Yeonsoo Lee said, "VARCO Sound has evolved into an 'AI platform designed for professional needs' that boosts creators' efficiency without disrupting their existing workflows." Yeonsoo Lee added, "We will establish a new paradigm in the global audio creation ecosystem through continuous technological advancement and seamless integration with a wide range of external platforms."
