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
