hello im working on a graphic equalizer in visual basic but ive run into a few problems while doing this, first:

1. does anyone know any sort of syntax to use when trying to fetch properties of a file? example a wav file with how long the time of the file is? i need to know this so that i could use a progress bar to slide across coherently with the song or sample as it plays.

2. Im trying to figure how can i possibly modify audio signal frequencies in visual basic where audio commands are lacking. i know as much as the logic of having an array for frequencies 20 - 16 000 hz, making the array have 15 980 slots for data. and too boost the frequencies i know it will have to increase or decrease exponentially as a normal graphic equalizer does.


this is my logic so far of how i go about doing this, but how do i actually access the data stream from the wav file so that i can edit audio signals either boost/cut them as an actual equalizer does?

any help or advice would be appreciated, hope there are some audio nerds here like me that can help me with this Wink
