Sound possibilities that make a difference

Achieving the best sound quality for each of your talent's voices

Sound4 Big voice’s philosophy is to allow complete customization of presets for each talent. This is the only way to bring out the best in each performer.
Address acoustic issues

The X1.CL features a unique 3-band noise gate management system. Its algorithms work rapidly, effectively cleaning up residual background noise. This is a key feature for talk shows when several microphones are simultaneously open.
A confortable GUI with Undu/Redu

At SOUND4, we pay great attention to the user interface experience. Ergonomics is our aim, but we also provide functions that make users confident in their use of the product. You'll never feel lost, and our undo/redo function offers a solution to go back and forth if you're not satisfied with your changes.
Create a unique sound identity through voice processing

X1.CL's powerful processing chain enables radio stations to create a unique vocal sound identity. By customizing pre and pos EQs, 3-band gate, 3-band processing, the final limiter, it shapes a consistent, recognizable vocal character that becomes synonymous with the station's brand. This enhances listener experience and reinforces brand recognition, making the station instantly identifiable through its signature vocal sound.
Enhance the clarity of debates

With Dominate it function, you can set up your hosts managing debates to automatically lower guest microphone levels and take priority when participants are talking over each other. The result is simply amazing!

Specifications

Typical CPU use

The processing engine consumes 65 MHz. Typically and with a headroom for security, a user will be able to run 175 X1.CL on a 4 cores processor running at 3 GHz. Of course, this depends on the processor's generation.

OS Compatible

On Windows operating systems (w10, w11, Server 2019, Server 2022), X1.CL is available with Virtual Driver, ASIO, VST3 and the native DLL engine for software integrations. On Linux, only the DLL is available for product integration for the moment.

Recommended Instruction-sets capacities

For high density applications, we recommend CPU armed with AVX2 (or better AVX512F).

User interface

For making sound setup and controlling everything, X1.CL is armed with a super ergonomic user-friendly HTML5 GUI. A second GUI for live applications will be soon available, in this version, it is only possible to recall a preset or mute a Mic only.

Ready to use in those architectures
