Spectra C1 is a wideband compressor designed for a broad range of audio applications including vocals, instruments, track compression, and gentle mastering tasks. It offers smooth soft-knee compression and expansion, providing precise control over dynamics while maintaining the natural tone of the original audio. This makes it suitable for both subtle and more pronounced dynamic shaping.

At the core of Spectra C1 is a proprietary physics-based audio processing engine that allows users to easily tailor the compressor's impact to their desired sound. The interface features a unique and intuitive gain-reduction meter alongside a VU meter, facilitating clear visual feedback during mixing and mastering. This helps users achieve transparent compression that preserves the integrity of the source material.

Spectra C1 supports full parameter automation within the host environment, enabling detailed dynamic control in complex sessions. It operates with zero latency and offers high-resolution processing with 64-bit internal precision and support for 24-bit/96 kHz audio. Additionally, it maintains mono compatibility, ensuring consistent results across different playback systems.
