We need implementation of an analog filter circuit into an app. The app will be a music player and the filter is an effect that can be applied upon pressing a button or clicking a symbol.
The app in the first iteration is for demo use only and it need to be able to play 44,1 kHz wav files with the filter bypassed and with the filter turned on.
Each input channel (xr & xl) has to be filtered through two different transfer functions: H1(z) & H2(z).
The two output channels (yr & yl) are the sum of the outputs from each filter according to:
yr = xr*H1(z) + xl*H2(z)
yl = xl*H1(z) + xr*H2(z)
The original analogue filter has transfers functions with two poles and two zeros in the s-plane, hence those transfer functions can be transformed to the z-plane in a biquad-filter structure.
There is a rudimentary audio player app for android with a faulty filter implementation. We can provide ths source code for reference.
We will provide filter implementation as well as koefficients for 44,1 kHz playback.
