I meant analog audio capture for NTSC:

*Analog Audio Capture

*The CX2388x captures and decodes all major terrestrial broadcast audio 
standards.
The CX2388x digitizes and oversamples the low Intermediate Frequency 
(IF) signal
from a Television (TV) tuner, and extracts and decodes the broadcast 
audio signal.
The decoded audio is sample rate converted to a 48 kHz Pulse Code 
Modulation
(PCM) stereo signal to simplify processing and interfacing. This 48 kHz 
stream can
be routed to the built-in +85 dB Signal-to-Noise Ratio (SNR) stereo 
audio Digital-to-
Analog Converters (DACs) for connection to the PC’s sound card or 
headphones, to an
external digital-audio interface, or to the PCI bus and host for direct 
capture by a
software audio codec.
If capture of line-level stereo audio signals is required, an 
inexpensive audio Analog-to-
Digital Converter (ADC) can be directly connected to the CX2388x’s I2S 
input port
and controlled via the serial bus master.
