RX removes hiss and buzz, eliminates clicks and crackles, and repairs overload distortion in audio. The amazingly intelligent spectral repair algorithms can analyze and fill gaps in audio files to restore previously unusable recordings. RX's modules are capable of great results quickly for producers of time sensitive material for broadcasting, podcasting, video production, and studio recording. RX Advanced has more features and a higher level of control needed in critical applications such as forensics, audio remastering and archiving.

The key modules in RX are defined by their specific task. They start with Denoiser that suppresses broadband and tonal noise independently without harsh artifacts. Spectral Repair removes intermittent noises and even fixes gaps and corrupted audio using advanced re-synthesis techniques. Declipper saves previously unusable recordings by removing both analog and digital clipping. Hum Removal cleans up hum in audio recordings caused by poor wiring and other electrical problems. Declicker removes clicks and pops from records and master tapes by removing analog and digital impulse noises.
