CEDAR enhances Debuzz, and the German Air Accident Investigation Bureau becomes its first customer
5 July 2002
CEDAR Audio Ltd announces an important enhancement to its award-winning Debuzz process running on CEDAR for Windows. This increases the upper limit of the fundamental frequency from 120Hz to more than 440Hz and makes Debuzz v2.03 capable of eliminating problems across a much wider range of audio forensic problems than before.
Audio Engineer, Tony Webster explains, "With an upper limit of 120Hz, it was impossible to home in on the fundamentals of problems such as GSM (mobile telephone) interference and buzzes introduced by the high frequency electrical systems found in aircraft. Previously, we could achieve quite a lot by basing the noise reduction on a subharmonic, but now I can select the precise frequency of the problem. This is a huge improvement. Using the new Debuzz process together with Declick, I can now achieve a significant increase in intelligibility, with obvious important benefits when working on covert surveillance recordings and aircraft 'black box' analysis."
The German Air Accident Investigation Bureau (BFU) has become the first customer for the new Debuzzer. Uwe Seyfert, CEDAR's German distributor, specifically requested the new version for BFU because the Bureau frequently encounters noise problems with fundamentals of 400Hz, the frequency of the electrical power systems within many commercial aircraft.
As with all CEDAR for Windows products, upgrades to Debuzz 2.03 are free of charge to all existing owners of the process.
