Denoiser DSP Board STC-H209 SDK Compact digitalreal-time noise filtering board

Description

Denoiser DSP board allows to integrate modern technology of broadband noise filtering in any type of audio processing, transmission or recording equipment.

This board was designed to be embedded into any appropriate unit, for example, headset, voice recorder or radio, suppressing broadband noise and improving speech signals. Currently Denoiser DSP board is successfully employed in:

• radio sets (for paddock-driver communication in american NASCAR racing)
• audio surveillance devices
• internal communication equipment of huge industrial facilities

Speech Solutions Award as
"Best Input Device Solution"
at SpeechTEK 2003 in New York

Applications

Telecommunication: phones, mobiles, hands- free kits, headsets, and others.

Aircraft communication: speech of aircraft pilots and dispatchers becomes more intelligible, that leads to more safety.

Dictation devices and voice logging systems: time of speech transcribing decreases (up to 2 times).

Highlights

• Effective street, car, industrial and other broadband, harmonic and pulse-like noise and interference suppression in one or two channels
• Effective suppression of any noise type using "reference channel" scheme (stereo filtering)
• Compact size (may be customized upon request), easily embeddable
• No adjustments needed for operation

Specifications

• Overall Signal-Noise-Ratio (SNR) improvement - up to 30dB
• Tonal noise suppression - up to 50dB
• Broadband noise suppression - up to 15dB
• Sampling rate – up to 22050 Hz
• Two-channel analog I/O
• Size - 50x40x6 mm, (1.97x1.57x0.23 in.)
• Voltage - 4.5 V
• Power consumption – 80 mA

Delivery set

There are three Denoiser DSP board applications available:

1. Denoiser DSP board

Denoiser DSP board application includes only STC-H209 Denoiser DSP board to be embedded into customer's application.

2. Denoiser Set

Denoiser Set includes STC-H209 Denoiser DSP board mounted on STC-H210 sound I/O board. With this additional board, embedding Denoiser DSP into your applications and devices is usually much easier.

3. Denoiser Development Kit

Denoiser Development Kit is the most complete Denoiser DSP application. In addition to STC-H209 and STC-H210, it also includes additional STC-H230 interface board, full set of audio cables, noise-filtering algorithm adjustment software, power supply and other necessary equipment.

With Denoiser Development Kit you may not only embed the board, but also adjust the algorithm parameters to better suit your specific tasks.
