How to Get Channel Info From Recording Input?

Hey there! I had a question on using ManagedBass to get spectrum data from a recording input.

I believe I'm already successfully able to enumerate and set the recording device, now I just need to set up some kind of loop where I read the recording input, and then save the amplitude values for low/med/high frequencies to an array.

Also, there's potential that the recording input would be a stereo source.

How to implement a 3-band equalizer?

So I tried this:

 public void TurnOnEQ()
        {
            ManagedBass.Fx.PeakEQParameters eq = new PeakEQParameters();
            Bass.ChannelSetFX(handle, EffectType.PeakEQ, 0);
            eq.fGain = 0.0f; // the initial gain (here 0dB)

            // now for each band do the following
            eq.lBand = 0; // 1st band
            eq.fCenter = 60.0f; // 60Hz
            Bass.FXSetParameters(handle, eq);

            eq.lBand = 1; // 2nd band
            eq.fCenter = 170.0f; // 170Hz
            Bass.FXSetParameters(handle, eq);
        }
        public void UpdateEQ(int band, float gain)
        {
            ManagedBass.Fx.PeakEQParameters eq = new PeakEQParameters();

            // first get the EQ values of the selected band!
            eq.lBand = band;
            var result = Bass.FXGetParameters(handle, eq);

            // and now apply the new gain
            eq.fGain = gain;
           var result2 = Bass.FXSetParameters(handle, eq);
        }

This example I ported from a code posted on Un4seen forum by radio42. But the values of both result and result2 are always false and aside from that, nothing happens to the audio. I tried using PeakEQ from ManagedBass.Fx directly but I got this error:

Exception thrown: 'System.TypeLoadException'

Just wanted to ask, how to correctly implement an Equalizer?
