+I2S
+===
+
+ESP32-S3 has two I2S peripherals accessible using either the generic I2S audio
+driver or a specific audio codec driver
+(`CS4344 `__ bindings are
+available at the moment). The generic I2S audio driver enables the use of both
+the receiver module (RX) and the transmitter module (TX) without using any
+specific codec. Also, it's possible to use the I2S character device driver
+to bypass the audio subsystem and write directly to the I2S peripheral.
+
+The following configurations use the I2S peripheral::

+-----
+
+This configuration uses the I2S0 peripheral and an externally connected audio
+codec to play an audio file streamed over an HTTP connection while connected
+to a Wi-Fi network.
+
+**Audio Codec Setup**
+
+The CS4344 audio codec is connected to the following pins:
+
+============ ========== ============================================
+ESP32-S3 Pin CS4344 Pin Description
+============ ========== ============================================
+5 MCLK Master Clock
+16 SCLK Serial Clock
+7 LRCK Left Right Clock (Word Select)
+6 SDIN Serial Data In on CS4344. (DOUT on ESP32-S3)
+============ ========== ============================================
+
+**Simple HTTP server**
+
+Prepare a PCM-encoded (`.wav`) audio file with 16 or 24 bits/sample (sampled at
+16~48kHz). This file must be placed into a folder in a computer that could
+be accessed on the same Wi-Fi network the ESP32 will be connecting to.
+
+Python provides a simple HTTP server. ``cd`` to the audio file folder on the
+PC and run::
+
+ $ python3 -m http.server
+ Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/)
+
+Look for your PC IP address and test playing the prepared audio on your

+Once connected, open NuttX's player and play the file according to the filename

+nxlooper
+--------
+
+This configuration uses the I2S1 peripheral as an I2S receiver and the I2S0
+peripheral as an I2S transmitter. The idea is to capture an I2S data frame
+using an I2S peripheral and reproduce the captured data on the other.
+
+**Receiving data on I2S1**
+
+The I2S1 will act as a receiver (in slave mode, i.e., waiting for the BCLK
+and WS signals from the transmitter), capturing data from DIN, which
+needs to be connected to an external source as follows:
+
+============ ========== =========================================
+ESP32-S3 Pin Signal Pin Description
+============ ========== =========================================
+18 BCLK Bit Clock (SCLK)
+17 WS Word Select (LRCLK)
+15 DIN Data IN
+============ ========== =========================================
+
+**Transmitting data on I2S0**
+
+The I2S0 will act as a transmitter (in master mode, i.e., providing the
+BCLK and WS signals), replicating the data captured on I2S1.
+The pinout for the transmitter is as follows:
+
+========== ========== =========================================
+ESP32 Pin Signal Pin Description
+========== ========== =========================================
+5 MCLK Master Clock
+16 BCLK Bit Clock (SCLK)
+7 WS Word Select (LRCLK)
+6 DOUT Data Out
+========== ========== =========================================
+
+.. note:: The audio codec CS4344 can be connected to the transmitter pins
+ to reproduce the captured data if the receiver's source is a PCM-encoded
+ audio data.
+
+**nxlooper**
+
+The ``nxlooper`` application captures data from the audio device with input
+capabilities (the I2S1 in this example) and forwards the audio data frame to
+the audio device with output capabilities (the I2S0 in this example).
+
+After successfully built and flashed, run on the boards' terminal::
+
+ nsh> nxlooper
+ nxlooper> loopback
+
+.. note:: ``loopback`` command default arguments for the channel configuration,
+ data width and sample rate are, respectively, 2 channels,
+ 16 bits/sample and 48KHz. These arguments can be supplied to select
+ different audio formats, for instance::
+
+ nxlooper> loopback 2 16 44100
