Type : Bit-reducer and sample&hold unit
References : Posted by tobyear[AT]web[DOT]de
Notes :
This is a simple bit and sample rate reduction code, maybe some of you can use it. The parameters are bits (1..32) and rate (0..1, 1 is the original samplerate).
Call the function like this:

A VST plugin implementing this algorithm (with full Delphi source code included) can be downloaded from here:

Comments/suggestions/improvements are welcome, send them to:

Code :
// bits: 1..32
// rate: 0..1 (1 is original samplerate)

********** Pascal source **********
var m:longint;

// call this at least once before calling
// decimate() the first time
procedure setparams(bits:integer;shrate:single);
m:=1 shl (bits-1);

function decimate(i:single):single;
if (cnt>1) then

********** C source **********
int bits=16;
float rate=0.5;

long int m=1<<(bits-1);
float y=0,cnt=0;

float decimate(float i)
if (cnt>=1)
  y=(long int)(i*m)/(float)m;
return y;

comment : Nothing wrong with that, but you can also do fractional-bit-depth decimations, allowing smooth degradation from high bit depth to low and back: --------------------------------------- // something like this -- this is // completely off the top of my head // precalculate the quantization level float bits; // effective bit depth float quantum = powf( 2.0f, bits ); // per sample y = floorf( x * quantum ) / quantum; ---------------------------------------

comment : it looks to me like the c-line long int m=1<<(bits-1); doesnt give the correct number of quantisation levels if the number of levels is defined as 2^bits. if bits=2 for instance, the above code line returns a bit pattern of 10 (3) and not 11 (2^2) like one would expect. please, do correct me if im wrong. /heatrof

comment : just getting into coding, i've mainly been working with synthedit...but would really like to move on into the bigger arena? any pointers for a DSP newbie-totally not hip on structured programming...yet! :O)

comment : Having defined the vital terms of the contract, the contract will set forth the exact terms of the agreement. Most policies are written in outline form and organized around sections. Each section of the QuotesChimp covers one specific topic of the agreement. For example, Section I of a homeowner's insurance policy deals with property coverages, and Section II with liability. Thus, each area of the contract that deals with property coverage in the policy will be labeled as "Section I" material and each part that sets forth the terms of liability coverage will be labeled as "Section II." Most policies have several sections within each insurance agreement.
