DSP-based PCB Design:

ElaraTek offers DSP-based hardware PCB design for commercial and specialist headsets, amplifiers and acoustic limiting devices.

The basic designs offer the following features:

• Low power DSP with 2 independent comms channels with integrated high quality audio CODECs
• Customised SonoKlara® DSP software to meet your requirements for noise/echo/side-tone cancellation, acoustic shock protection, speech enhancement and noise dose monitoring & control
• Software compliance with noise and acoustic safety legislation
• Upto 18dB microphone gain on the transmit channel
• Auto bypass of DSP when battery power is too low
• DSP software upgradeable
• Software code security
• Industry standard acoustic limiting circuitry
• Small form-factor PCB to easily fit inside the headset ear-cup Independent left & right comms channels makes this design suitable for aviation, military and emergency services application

Call Centre Amplifier Product:

ElaraTek offers DSP-based Amplifier to enhance the performance of call centre and office telephony headsets and consols. The SonoKlara® SK200 Amplifier incorporates sophisticated acoustic shock protection technologies and noise dose measurement inline with Noise at Work Legislations and EU Directive 2003/10/EC. The SK200 significantly reduces risk of injuries from acoustic shock and noise-induced hearing loss through headset, while enhancing speech clarity & voice intelligibility.

Other features include:

• Noise reduction
• Speech enhancement
• User selectable voice equalisation
• Noise dose measurement & control
• Easy setup with voice tag confirmation
• Works with both standard electret-mic consols and carbon-mic consols
• Small unit that can be attached to the telephone consol
• Addresses critical safety shortfalls in call centre hearing protection
• Reduces fatigue and enhances agents' quality of life

Bluetooth Headset & Hands-Free:

ElaraTek offers a highly integrated and optimised DSP software solution for  BlueCore5-Multimedia (BC5-MM) Bluetooth chipset from CSR. It includes:

• 1-mic / 2-mic noise reduction for transmit channel
• Noise reduction and speech enhancement in receive channel
• Acoustic echo cancellation
• Noise dependent auto volume control
• Active & passive exposure monitoring for stereo music headsets
• Music equalisation profiles (bass, treble, rock, classic)

Mobile Phone and Personal Mobile Radio (PMR/PTT):

ElaraTek’s suite of voice quality and speech enhancement algorithms provide ideal solution for mobile phones and personal mobile radios with either 1-mic or 2-mic implementation. Mobile communication is enhanced significantly by reducing background noise in both incoming and outgoing channels. Additionally, noise-dependent volume control automatically adjusts the volume of the incoming signal in proportion to the amount of noise present.
