Waves Releases Restoration Tools, Doubles Speed of Native Plug-Ins

Establishes New Standard With Noise Reduction And Restoration (September 21, 2001)
WAVES LTD., a leading supplier of audio signal processing solutions for the professional audio and multimedia markets, has today announced the release of the Restoration processor bundle for Native (PC and Macintosh) platforms. Removal of unwanted background noise and disturbing signal transients without affecting the original sound has always been a major challenge in audio postproduction, remastering, broadcasting, video, film and forensics. Waves audio processing Plug-Ins are the quality standard for thousands of top audio professionals all over the world. Waves new Restoration bundle has addressed the increasing demand for real-time noise and transient elimination tools. It establishes a new standard for quality and simplicity in software based noise reduction and sound restoration tools for post-production, remastering, and forensics applications.

The Restoration bundle includes four new Plug-Ins; X-Noise, X-Click, X-Crackle, and X-Hum, all based on the outstanding audio restoration technology licensed from Algorithmix GmbH, Germany. X-Noise intelligently learns from a section of noise, and then applies a broadband noise reduction to eliminate background noise from any source. X-Click effectively removes clicks from 78's or vinyl records, as well as spikes arising from digital switching or crosstalk. X-Crackle is the second stage in the restoration of old records eliminating crackles and surface noise left after the X-Click process. X-Hum attenuates steady pitched low frequency disturbances, such as ground loop hum and its harmonics. It is also intended to reduce the rumbles, microphone pops, and even DC-offset.

"Waves new Restoration plug-ins allowed me to do some great work and stay within budget on restoring and remastering an old album. Linda Hopkins' Me and Bessie originals from the '70s were lost and the vinyl I received was in rough shape, but the Restoration tools did an amazing job of cleaning this up," said Jim Watson, FAT GROOVE Productions.

"Audio post-production requires removal of distortion, air conditioning noise and other time consuming audio clean-up. Waves' new Restoration bundle offers sonic quality as good my reference hardware system, but the Waves plug-ins allows me to tweak and work in real-time. I can hear the results immediately, so I can work faster and more efficiently," said Bryen Hensley, Post Effects.

"Our Restoration tools address the fundamental problem of broadband and impulse noise elimination," stated Gilad Keren, CEO of Waves Ltd. "Early users indicate that the signal restoring quality is comparable to the high-end $10,000 plus reference hardware tools, while offering dramatically simpler real-time operation. It is an ideal tool set for mastering, film, video postproduction, archiving, and forensic professionals. "


WAVES LTD. also announced a variety of coding efficiency improvements have been made to several of its most powerful plug-ins. These coding improvements have no effect on functionality or sonic quality, but they can dramatically increase the number of plug-in iterations available on processing limited host CPUs. Many initial users have seen the number of Waves plug-ins iterations double.

Audio signal processing is a processor demanding application and many users need DSP hardware acceleration to achieve the processing bandwidth necessary to support their signal processing requirements. With the latest GHz processors, Native or host based audio processing is becoming more powerful. To help support these customers Waves has improved their Native coding efficiency allowing up to twice as many plug-in iterations on Macintosh and PC based systems.

Waves is pursuing a variety of coding efficiency improvements such as using the latest compilers and coding for SIMD (Single Instruction Multiple Data) instructions on Intel Pentium, Advanced Micro Devices Athlon, and Motorola Altivec processors. The improvement in efficiency varies by plug-in and target platform, but efficiency improvements in some initial cases have doubled. Higher efficiency plug-in code for Waves award-winning C4 and Renaissance Reverberator is now available with additional plug-in code available over the next few months. All of these code updates will be offered for free to current version 3.x customers at Waves website at

"I am finding that version 3.2.1 of Renaissnace Reverberator is seeing a >200% performance improvement on the PC. On my 1.4GHz AMD Athlon system I can run 14 of them, whereas before I could run only 4." - Scott Reams, LiquidDAW

"The SIMD efficiency improvements on the C4 allowed by to run up to 13 native C4s on my Pentium4 1.7 GHz machine, while previously I could only run 6. I also managed to get a great improvement with the Renaissance Reverberator. I went from 4 native R'verbs, to 11, with the new optimized version. The new software works great and I have noticed no effect on quality or functionality." - Mat Jarvis

"I am impressed by the optimization. On my 1GHz Pentium3 machine, Renaissance Reverberator CPU usage dropped from 38% to 17%" - Joeri Vankeirsbilck
