The differences between the three processors in the ADAU144x family are the ASRC (asynchronous sample rate converter) configurations. ADAU1442: Eight 2-channel ASRCs. Data is routed in stereo pairs (2 channels at a time). A total of 9 sample rates (clock domains) can be used simultaneously in the system, which can be distributed between the

Audio on Compact Disc has a sampling rate of 44.1 kHz; to transfer it to Digital Audio Tape, which uses 48 kHz, method 1 above can be used with L = 160, M = 147 (since 48000/44100 = 160/147). For the reverse conversion, the values of L and M are swapped.

Asynchronous Sample Rate Converter OVERVIEW The SM5950BM is a digital audio signal asynchronous sample rate converter LSI. It supports 16/20/24-bit word-length input/output interface data. It also features a built-in digital deemphasis filter and direct mute functions. FEATURES Functions L/R 2-channel (stereo) processing Sample rate conversion.

The DIR lock range includes sampling rates from 20kHz to 216kHz. The SRC4382 is configured using on-chip control registers and data buffers, which are accessed through either a 4-wire serial peripheral interface (SPI) port, or a 2-wire Philips I2C bus interface. There are two classes of sample-rate converters; syn- chronous and asynchronous. In synchronous sample rate converters, the incoming sample rate needs to be converted to a new sample rate by a ratio of simple integers (3:2, for example). Manuscript received August 20, 1993; revised November 11, 1993. Effects of Asynchronous Sample Times. Output signal is the input signal converted to the sample rate you specify. The default configuration ensures safe and deterministic data transfer. The sldemo_fuelsys model shows how to use the Rate Transition block to convert signals between continuous time and discrete time. Open Example. Block

Asynchronous Sample Rate Conversion. Asynchronous sampling frequency makes non-multiple modifying sampling frequency of audio signal. Algorithm: 1) Increasing up of sampling rate to frequency, multiple target signal's sampling frequency. Sample rate increasing makes by inserting additional samples between samples of input digital signal.
