Combining samples results in downsampling


    Feb 28 2013 | 11:31 am
    I'm trying to fill a buffer with chunks of another buffer. It seems to work well but I get a downsampling effect. The problem must be in my java code, can someone verify please?
    public void combine(final String frombuf, final long recTimeInSamples) {
    
    		final int channel = 1;
    		float[] recordBuffer = MSPBuffer.peek(frombuf, channel);
    		float[] playBuffer = MSPBuffer.peek(buffer, channel);
    		float[] result = new float[playBuffer.length];
    		long length = MSPBuffer.getSize(buffer);
    
    		int iters = (int) length / (int) recTimeInSamples;
    
    		for (int y = 1; y < iters + 1; y++) {
    			for (int i = 0; i < (int) recTimeInSamples; i++) {
    				result[i * y] = (recordBuffer[i]) + (playBuffer[i * y]);
    			}
    		}
    
    		MSPBuffer.poke(buffer, channel, result);
    	}
