Integrated DSP Module
We offer DSP
hardware design based on ultra-low power BelaSigna300 DSP from On
Semiconductor as well as CSR's Bluetooth embedded Kalimba DSP with
customised firmware for bespoke applications.
ultra-low power BelaSigna300 DSP module (<3mA @ 1.8V)
- multiple input
channels for comms and talk-through microphones
- independent left
and right comms channels
- integrated high quality audio CODECs
- customised DSP software
for telephony and multimedia applications
- compliancy with
acoustic safety guidelines and noise legislation
- software code security and upgradability
- up to 18dB gain on transmit channel for carbon-mic consoles
- auto bypass of DSP when battery is low, to ensure critical
- tiny form-factor
We offer DSP-based
critical safety shortfalls in call centre hearing protection.
ElaraTek's SonoKlara® DSP Amplifiers incorporate
sophisticated acoustic shock protection and noise dose measurement
and control, compliant with Noise at Work Legislations and EU Directive 2003/10/EC.
SonoKlara® DSP Amplifiers protect operators' hearing from a wide range
of acoustic incidents and thus significantly reduce the risk of injuries from
acoustic shock and noise-induced hearing loss through the headset. They
improve quality of life and performance of call centre Agents by enhancing voice
reducing operator fatigue.
We offer a highly
integrated and optimised DSP software solution for
Kalimba embedded DSP on CSR's Bluetooth chipsets. Features include:
1Mic / 2Mic noise reduction for transmit channel
- noise reduction and speech enhancement in receive channel
- acoustic echo cancellation
- noise dependent automatic volume control
- acoustic exposure monitoring
and control for stereo BT headsets
- music equalisation (bass, treble, rock, classic)
Mobile Phone and
Personal Mobile Radio (PMR/PTT)
suite of voice quality and speech enhancement algorithms provide ideal
solution for mobile phones and personal mobile radios (or PTT radios) with 1Mic
or 2Mic design. Mobile communication is significantly enhanced by reducing background noise in both incoming and outgoing channels.
Additionally, noise-dependent volume control automatically adjusts the
volume of the incoming call in proportion to the amount of ambient noise.
