Voice and video communications over the Internet are here to stay. Ever-growing numbers of individuals and businesses alike are replacing telephones and connecting through the Net. But as the novelty of VOIP fades and demand increases, users are becoming aware of its limitations, most notably poor voice quality. We find ourselves straining to understand others and shouting into (or at) our computers. Cell phones, too, are plagued by their own set of sound problems. Users expect a phone call to sound good regardless of the technology, so any device that delivers improved dialog intelligibility offers real, tangible advantages.

Sound problems are so common that we take it for granted that this is the price we  pay for the convenience and economy of portable communications. But it needn’t stay this way. Waves, renowned for its award-winning audio processing tools that make music, television, movies, and games sound great, has developed a unique  set of technologies that make VOIP and cell phone communications come alive at home, in the office, outdoors  – wherever you are.

MaxxVoice, the ultimate voice and communications solution, is a suite of state-of-the-art technologies that provide cutting-edge input processing for intelligible, noise-free conversation. Based on the same professional Waves processors used in audio forensics and post-production facilities, MaxxVoice includes innovative directional and adaptive background noise reduction, advanced echo cancellation, intelligent volume and dynamics controls and more, so you can be heard and hear, loud and clear.

MaxxBeam™ Microphone Array Noise Suppression

 MaxxBeam directional noise reduction for integrated microphones overcomes the challenges of noisy environments to capture crystal-clear, intelligible voice signals.

Based on microphone-array technology, MaxxBeam differentiates between the desirable signals inside the “beam” and undesirable sounds outside of it, suppressing both stationary and non-stationary noise from outside the beam.

 MaxxBeam’s Auto Beam feature is a non-static, directionality steering function which enables the beam to track and locate the main speech source, giving users the freedom and flexibility to communicate anywhere and everywhere through their device.

Honing in not just on the speaker, Auto Beam also controls the width and scope of the beam automatically, gradually adjusting to the user’s position and focusing in on their voice to deliver a clear, pure signal.


This allows MaxxBeam to suppress stationary and non-stationary noise from outside the beam, while providing optimal sound quality and clarity. MaxxBeam’s Real-time Configurable Beam Direction lets users instantly focus the array from narrow directional beams for single users to wider beams for conference calls. At narrow beam settings, MaxxBeam attenuates all signals originating from outside the beam; at wide settings, diffuse noise and room reflections are suppressed.

MaxxBeam offers tremendous microphone placement flexibility, and works with any matching microphone pair. MaxxBeam is perfect for consumer-grade microphones, and its Automatic Microphone Calibration compensates for differences in microphone pairs. Best of all, MaxxBeam simplifies hardware design, and is compatible with a wide variety of microphone types.

  • Reduces noise, improves intelligibility
  • Automatic microphone calibration
  • Support for various microphone types
  • Flexible microphone placement
  • Real-time configurable beam direction
  • Single user and conference modes
  • No bundled hardware required

MaxxNR™ State-of-the-Art Noise Reduction

MaxxNR adapts to and eliminates background noise during online communications for clear vocal signals.

Based on the Waves WNS Noise Suppressor plugin originally engineered for professional audio post production facilities, MaxxNR uses adaptive multi-band dynamics with zero latency and no phase distortion, resulting in transparent, natural sound.

By automatically analyzing the input signal, MaxxNR determines which frequency ranges contain undesirable background noise, and dynamically processes these ranges alone, effectively reducing ambient and environmental sounds.



MaxxEC Advanced Echo Cancellation

Pretty much everyone who has ever used a cellphone has probably experienced it (experienced it): Those frustrating echoes that make normal conversation all but impossible. As we speak, we hear phantom voice signals which are frustrating at best and can even make us lose track of the conversation.

One cause of these phantom signals is an acoustic loop between the microphone and the speakers. In certain situations, sounds coming from the phone’s speaker—and their acoustic reflections—are picked up by the nearby microphone. As a result, words repeat themselves.

To minimize this effect, Waves developed MaxxEC, a true full-duplex echo canceller. Using proprietary algorithms developed for the music and post production industries, MaxxEC reduces echo leak and its room reverberation without adding processing artifacts that can make voices sound unnatural.

At last, VOIP and cellphone conversations sound like they should. Waves MaxxEC frees you from echo so that you can relax – and enjoy the conversational flow.  

MaxxEQ Paragraphic Equalization

Perfect for voice microphone input, MaxxEQ is a full spectrum 10-band equalizer which makes it easy to customize the voice input performance of any device, frequency by frequency.      

Inspired by professional audio Waves pro audio equalizers, MaxxEQ gives you the power to design EQ curves and shape frequency response with accuracy and ease, using up to 10 programmable filters with bell, shelf, low pass, and high pass, plus adjustable frequency, gain, and Q parameters. Just like its professional counterparts, MaxxEQ’s makes click-and-drag filter design quick and simple.

MaxxVolume® 4-Way Dynamics Conditioning

Small microphones used in portable devices typically have limited input capabilities, especially when it comes to human voice signals which vary from user to user.

To optimize their performance, Waves took our all-in-one dynamics processor, MaxxVolume, and configured it especially for input signals. Using a powerful combination of high level compression, low level compression, gating and leveling, MaxxVolume ensures a strong, steady voice input to your microphone, for clear, intelligible communications.

DeKey Keyboard Noise Attenuation

Whether multitasking with colleagues or secretly chatting with a friend, many of us type while we talk. Typing sounds might seem quiet to your ears, but once picked up by a telephone or computer microphone, your keystrokes sound huge, and can’t be easily filtered out by the brain.

DeKey harnesses the power of award-winning Waves processors to analyze and eliminate the annoying clicky sound heard over a phone or VOIP device. Communicating directly with your device’s OS, DeKey isolates telltale keystroke sounds and removes them without affecting voices. Plus, Maxx DeKey understands that not all clicks are the same, and it constantly adapts to the sounds, further minimizing artifacts. As a result, conversations are clearer and less stressful, and your clandestine typing goes unnoticed!


DeEsser Sibilant Sound Attenuation

Cell phones and VOIP applications transmit a great deal of information using a minimum amount of bandwidth. That means that unwanted vocal sounds are not only annoying, they steal important, limited resources. As a result, voices can sound unpleasant, unnatural and hard to understand. One common source of trouble is sibilance, the loud ss and sh sounds that are part of language. In the natural world, our ears and our brains are skilled at ignoring such sounds; microphones, however, are not that forgiving.

 Sibilance can overload sound processors and mask the sound you care about: the voice. The way around this problem is to control sibilance before it can do its damage. Maxx Voice DeEsser harnesses the same technologies that earned Waves a Technical GRAMMY® award. DeEsser painstakingly analyses the frequencies of the sibilance, and then removes only those sounds. The result: Reduced hissing sounds, leaving room for a cleaner, more detailed, more pleasant voice on the other end of the line.

From Their Ears to Yours

Jack Joseph Puig, eleven-time GRAMMY® award-winning producer/engineer (Lady Gaga, U2 and many others), realized that the sound he creates—using cutting-edge processors in a world-class studio, and drawing on his years of experience—often ends up on a smartphone with small, tinny speakers, or through inexpensive headphones. Listeners weren’t hearing the music at its best, so he decided to do something about it. He joined forces with Waves Audio to bring studio sound to listeners everywhere. Now, with MaxxAudio, the magic of the recording studio can be experienced on personal consumer devices.
