adjacent-sin-freq.ogg
A sine sweep from 20 Hz to 5 kHz, first with no effect, then with adjacent bits of increasing weight swapped (8-9, 10-11, 12-13, 13-14 and finally 14-15).
As the order of the bits increases, the effect becomes more evident. As the frequency goes up, it degenerates into aliasing.
| Bits 10 and 11 swapped | |
| Bits 12 and 13 swapped | |
| Bits 13 and 14 swapped | |
| Bits 14 and 15 swapped |

The input signal is a 100 Hz sine whose amplitude is brought linearly from 0 to 1 in 3 seconds then back to 0 in 0.5 seconds. It's first heard without any effect, then with adjacent bits of increasing weight swapped (8-9, 10-11, 12-13, 13-14 and finally 14-15).
For low order bits, the changes are quieter but faster for a given da/dt.
The result of swapping bits 13 and 14 :
| Amplitude 0.25 | |
| Amplitude 0.50 | |
| Amplitude 0.75 | |
| Amplitude 1.00 |

All 120 possible bit swaps : 0-1 through 0-15, then 1-2 through 1-15 and so forth until 14-15. The left part of the table below has been omitted because it's uninteresting (all near-sines).
