Magfan - I don't know how they could pass 20kHz with -3dB and 21kHz with -96dB using linear phase filters (Bessel) to avoid problems in passband. Bessel filters have poor rejection at up to 2x -3dB frequency no matter how many poles. Brick-wall filters not only create uneven delay for different frequencies (wrong summing of harmonics) but also have uneven (ripple) amplitude in the passband. Master tape is down-converted to 44.1kHz from 192kHz but I don't know details. It seems impossible to limit bandwidth to exactly 20kHz with brick-wall filter. Recording engineers - are you there?.... |
