AW: usb soundkarte z.b maya oder ähnliches. oder intern aber hochwertig
klar ist sie das! optisch/coax wandler hab ich auch, weis ja nicht was du damit vor hast.

Mode of operation: 16 bit 44 kHz
Frequency response (40 Hz to 15 kHz), dB: +0.03, -0.04 Excellent Noise level, dB (A): -95.2 Excellent Dynamic range, dB (A): 95.2 Excellent THD, %: 0.0011 Excellent Intermodulation distortions, %: 0.0054 Excellent Channel crosstalk, dB: -95.6 Excellent General performance: Excellent
The THD spectrogram at 44 kHz indicates minor 2nd and 3d harmonics and a clear spectrum
The IMD (SMPTE) spectrogram at 44 kHz reveals no artifacts from oversampling
Mode of operation: 16 bits 48 kHz Frequency response (40 Hz to 15 kHz), dB: +0.04, -0.32 Very good Noise level, dB (A): -95.4 Excellent Dynamic range, dB (A): 95.3 Excellent THD, %: 0.0011 Excellent Intermodulation distortions, %: 0.0055 Excellent Channel crosstalk, dB: -96.4 Excellent General performance: Excellent
The frequency response measured at 48 kHz shows a small smooth drop in the HF range over 10 kHz but it's beyond the aural perceptionMode of operation: 24 bits 96 kHz
Frequency response (40 Hz to 15 kHz), dB: +0.04, -0.34 Very good Noise level, dB (A): -100.2 Excellent Dynamic range, dB (A): 100.1 Excellent THD, %: 0.0011 Excellent Intermodulation distortions, %: 0.0055 Excellent Channel crosstalk, dB: -97.1 Excellent General performance: Excellent
The detailed results for the front output for 24 bits 96 kHz are here. Mode of operation: 24 bits 192 kHz
Frequency response (40 Hz to 15 kHz), dB: +0.03, -0.33 Very good Noise level, dB (A): -100.2 Excellent Dynamic range, dB (A): 100.0 Excellent THD, %: 0.0011 Excellent Intermodulation distortions, %: 0.0097 Very good Channel crosstalk, dB: -97.0 Excellent General performance: Excellent
The detailed results for the front output for 24 bits 192 kHz are here. Line-in
Mode of operation: 16 bits 44 kHz
Frequency response (40 Hz to 15 kHz), dB: +0.05, -0.29 Very good Noise level, dB (A): -86.1 Good Dynamic range, dB (A): 86.1 Good THD, %: 0.0020 Excellent Intermodulation distortions, %: 0.016 Very good Channel crosstalk, dB: -84.8 Very good General performance: Very good

The noise spectrogram in case of recording from the line-in demonstrates even and odd harmonics of the power-supply noiseMode of operation: 32 bits 96 kHz
Frequency response (40 Hz to 15 kHz), dB: +0.02, -0.30 Very good Noise level, dB (A): -86.2 Good Dynamic range, dB (A): 86.1 Good THD, %: 0.0044 Very good Intermodulation distortions, %: 0.020 Very good Channel crosstalk, dB: -82.3 Very good General performance: Very good The drivers work incorrectly in the record mode "24 bits 3 bytes int", that is why for 24 bits you should select "4 bytes int" for tests and wav editors. In general, the 32bit mode is more convenient and loads the processor to a less extent, that is why the lack of "3 bytes int" is better than it would be vice versa.

The digital input and output were connected with a cable supplied. The actual results will be a bit worse because of the source and the receiver being mistimed. Actually, an optical connection is a home version of the S/PDIF format for hot connection of equipment, that is why the Toslink interface would hardly be a bottleneck for quality. Mode of operation: 16 bits 44 kHz

The test results prove it as information is transferred nearly bit-to-bit.
