A Directshow filter, Which, (1)Separates the incoming audio stream into three (3) frequency bands (Low, Mid and High), (2)Displays the audio level of each Frequency band AND the entire stream in the form of equalizer Bars. (i.e. 4 bars)and includes a method to measure and store into a *.txt file the amplitude / audio level of each frequency band and the entire stream as being displayed in (2) (3)Changes the volume level of each band (Low, Mid and High) of the incoming audio stream and hence of the audio stream, based on the setting of each slider for each frequency band (low, mid and high) and,Include a method to change the amplitude / audio level of each frequency band and the entire stream as mentioned in (3), based on an input by another program, which shall pass the data to the filter or place it in the registry. Here every sample will have to be modified. (4)Then combines the modified stream(s) into an audio stream and passes it to the next Directshow filter / Directsound device. (5)Displays the audio level of each modified Frequency band AND the modified audio stream the in the form of equalizer Bars. (i.e. 4 bars)and Include a method to measure and store into a *.txt file the amplitude / audio level of each frequency band and the entire stream as being displayed in (5) Include a method to protect the filter from misuse, hence, when the filter loads, it will check for an entry in the registry and only if the entry is valid, will the filter continue to operate, else it will either refuse to connect or exit. This is similar to an audio equalizer Directshow filter. The Filter should be able to play all audio streams, PCM, MP2, MP3, AC3, etc. etc.
