Wolfwave Audio Filter

Wolfwave is a digital audio filter that very efficiently improves the intelligibility of a received signal. This is achieved by means of a multi-level and adaptive audio signal processing: the noise is reduced first, then a pass-for-umband filter and finally a equalizer for the adaptation to the user's hedes. Each of the levels can be adjusted individually, for example the equalizer, depending on sex and age, to be able to respond very precisely to personal listening habits. The audio filter is completed by a adjustable notch filter (notch filter). {

The Wolfwave filter is equipped with an easy reading OLED display, comfortable operation via the front with different buttons and rotating knobs. The display offers a good overview of the respective function, making the operation very simple. Once the settings have been found, they can be stored separately in multiple memories, depending on the application and the situation. Several settings, for example for the CW competition or the noisy SSB signal, can be quickly recalled. A "bypass" function is directly available, so you can easily compare the original and the filtered signal and turn up the filter if necessary. {

The connections are designed for NF and are easy to integrate into the existing station. Separate connectors for headphones and speakers are available as exits. A USB socket is used for firmware updates of the digital signal processor. The power supply is 12 V cc, the current consumption is only 60 mA. This makes the Wolfwave filter easy to use even with battery operation. {

The latest firmware update for Wolfwave adds a CW decoder, a low -consumption standby mode and other improvements. It also adds a start of start that we composed of a professional musician, Chris Rolinson G7ddn. The start sound is based on "WW" on the Morse code. {
