Before Change

        python generator: yields source output at microphones in blocks of 
        shape (num, numchannels), the last block may be shorter than num
        
        signal = fft.fft(self.signal.signal())
        pos = array(self.loc, dtype=float).reshape(3, 1)
        rm = self.env.r(self.c, pos, self.mpos.mpos)
        delays = exp(-2j*pi*(rm/self.c)*\
            fft.fftfreq(int(self.numsamples),1.0/self.sample_freq)[:,newaxis])
        out = fft.ifft(signal[:, newaxis]*delays, axis=0).real/rm

        while i < self.numsamples:
            yield out[i:i+num]

After Change

                out[i] = signal[array(0.5+ind*self.up, dtype=long)]/rm
                ind += 1.

                if i == num:
                    yield out
                    i = 0
            except IndexError:
                break
        yield out[:i]
