How can I resample wav file

Question

Currently I\'m recording an audio signal with following specs:

• Channels: 1
• SamplesPerSecond: 8000
• BitsPerSample: 16

How can I

AS3 function for resampling. You can easy change to convert this code to C#:

    private function resampling(fromSampleRate:int, toSampleRate:int, quality:int = 10):void
    {
        var samples:Vector. = new Vector.;

        var srcLength:uint = this._samples.length;
        var destLength:uint = this._samples.length*toSampleRate/fromSampleRate;
        var dx:Number = srcLength/destLength;

        // fmax : nyqist half of destination sampleRate
        // fmax / fsr = 0.5;
        var fmaxDivSR:Number = 0.5;
        var r_g:Number = 2 * fmaxDivSR;

        // Quality is half the window width
        var wndWidth2:int = quality;
        var wndWidth:int = quality*2;

        var x:Number = 0;
        var i:uint, j:uint;
        var r_y:Number;
        var tau:int;
        var r_w:Number;
        var r_a:Number;
        var r_snc:Number;
        for (i=0;i= 0) && (j < srcLength))
                {
                    r_y += r_g * r_w * r_snc * this._samples[j];
                }
            }
            samples[i] = r_y;
            x += dx;
        }

        this._samples = samples.concat();
        samples.length = 0;
    }
