+Emagic Audiowerk2 / Audiowerk8 Digital Audio Recording PCI
+
+Audiowerk2 HW:
+- SAA7146A (Multimedia PCI Bridge Scaler)
+- SAA7367 (Digital audio ADC bitstream conversion)
+- 2x TDA1315H (?)
+- 28-ish MHz (?)
+
+Back cover box claims:
+- 2x analog inputs (-10dBV, unbalanced RCA);
+- 2x analog outputs (-10dBV, unbalanced RCA);
+- 2x Stereo digital I/O (S/PDIF, RCA);
+- Bitstream A/D and D/A converters (128 oversampling);
+- Sample Rate 44.1 kHz;
+- THD: 0.006% @ 1 kHz, 0 dB signal level;
+- dynamic range: 92 dB, input-to-output, A-weighted;
+- Frequency response: 20 Hz to 20 kHz, -/+ 0.5 dB, input-to-output;
+- PCI busmaster;
+
+SAA7146A is also the basis of several other DVB-based capture cards
