SONAR TECHNIQUE
An improved sonar mechanism comprises an audio source from a sonar system. The audio source is processed in parallel by the following modules: a low pass filter with dynamic offset; an envelope controlled bandpass filter; a high pass filter; and adding an amount of dynamic synthesized sub bass to the source audio. The processed audio is then combined in a summing mixer with the audio source.
1 . An improved sonar mechanism comprising:
An audio source from a sonar system;
Processing the audio source by the following modules:
a low pass filter with dynamic offset;
an envelope controlled bandpass filter;
a high pass filter; and
adding an amount of dynamic synthesized sub bass to the audio;
Combining the processed audio signals in a summing mixer with the audio source.
2 . The mechanism of claim 1 , wherein the number of modules is four.
3 . The mechanism of claim 1 , wherein the low pass filter has a ranage of 40 htz to 20 Khtz.
4 . The mechanism of claim 1 , wherein the envelope controlled bandpass filter comprises three processing blocks as follows: an envelope follower modulation amount; a frequency range; and an output block.
5 . The mechanism of claim 1 , wherein the high pass filter comprises three processing blocks as follows: an HP filter frequency; a tube simulator sound block; and an output block.
6 . The mechanism of claim 1 , wherein the sub bass has a frequency of 120 Htz or less.
