Colsan can provide a range of Digital Signal Processing (DSP) platforms to best suit your requirements.As an independent supplier of DSP hardware and software we can advise you on the best platform for your products. Colsan has developed a large family of noise reduction and speech enhancement algorithms suitable for most applications from Hearing Aid to Mobile communications.

Algorithms

  All algorithms are currently directly available for licensing for desktop as well as embedded applications. Our engineers will be glad to assist you in optimizing those algorithms for your specific applications and porting them to the hardware platform of your choice. We will also be glad to help you identify the most effective product for your noise problem.

Algorithm Applications
Active Noise Cancellation (ANC) Headsets for factory workers or airport ground staff
Active Noise Reduction (ANR) Hearing protection headsets
Acoustic Feedback Control (AFC) Where microphones are close to speaker in small cavities. For example In The Ear (ITE) headsets
Automatic Gain/Volume Control Ear defenders used for hunting or on the shooting range.
Acoustic Echo Canceller (AEC) (short or long-path) Conference calls, full duplex applications
Multiband Dynamic Range Compressor (Multi-DRC) Headsets for factory workers or airport ground staff
Wind Noise Suppression (WNS) Headsets used in out door environments (oil rig, airport ground staff, battle field etc.)
Equaliser (EQ) Any headset, microphone  or speaker product
