iZotope Announces RX Audio Restoration Software

October 5, 2007

Remove noise, hum, clipping, clicks, and restore audio in critical applications.

AES - NYC Booth 466 (October 5, 2007) — iZotope, Inc., a leading innovator in audio signal processing technology, announces iZotope RX™ audio restoration software, a new standalone application featuring the essential tools for cleaning and restoring audio.

Using powerful, newly developed technology created by iZotope's research team, RX removes hiss and buzz, eliminates clicks and crackles, and repairs overload distortion in audio. New intelligent spectral repair algorithms can even analyze and fill gaps in audio files to restore previously unusable recordings.

Ideal for any application that demands spotless audio, RX features a unique interface designed specifically for audio restoration work. Preset modules attain great results quickly for time sensitive applications like broadcasting and podcasting, video production, and studio recording. Advanced features allow a level of control needed in critical applications such as forensics, audio remastering and archiving.

"There are more sources of recorded audio today than ever before - cell phones, video cameras, computers, old vinyl records, tape - the list goes on," says Jeremy Todd, CTO of iZotope, Inc. "With RX, we've made our next-generation restoration technology accessible to anyone needing clean and clear audio."

RX includes groundbreaking features designed to simplify the process of cleaning and repairing recordings. State of the art analysis tools such as an advanced spectrogram with the greatest time and frequency resolution available allow a finer degree of detail work. Isolate and fix damaged audio with selective processing and Spectral Repair. The Compare Settings feature auditions parameters quickly, and a non-destructive undo history makes reverting to previous states simple and flexible. Batch processing makes applying multiple processes to large files much less time consuming.
