Audigy 2: Input/ Output Quality, Continued
| Parameter | Left | Right |
|---|---|---|
| IMD + Noise, %: | 1.482 | 1.393 |
| IMD + Noise (A-weighted), %: | 1.333 | 1.253 |
| Parameter | L <- R | L -> R |
|---|---|---|
| Crosstalk at 100 Hz, dB: | -80 | -80 |
| Crosstalk at 1 kHz, dB: | -84 | -84 |
| Crosstalk at 10 kHz, dB: | -76 | -82 |
For your information, the restored sound is of the same quality on the card's three analog outputs, apart from a definite drop of about 10 dB in the signal-to-noise ratio on output 3. This does not stop this output from being better than the main outputs on middle-range sound cards.
Here are the 16 bit/ 48 kHz results:

The following results show the quality of the Audigy 2 in 24 bit/ 96 kHz recording via the line-in stereo input. The test line was: DMX 6Fire 24/ 96 Stereo Out - Audigy 2 line in.

| Frequency response (from 40 Hz to 15 kHz), dB: | +0.01, -0.11 | Excellent |
| Noise level, dB (A): | -90.1 | Very good |
| Dynamic range, dB (A): | 87.7 | Good |
| THD, %: | 0.0022 | Excellent |

So no trouble with recording then; the Audigy 2 is a good card for 24 bit/ 96 kHz recording. The subjective tests also showed that a significant effort has been made with recording from an analog source. The sound is a bit less "plump" with less coloration than on the previous cards, and benefits from the extra precision of the 24 bit/ 96 kHz.
