''TBDThe Audio interface available on AURA is based on i.MX93 SoC. The audio port supports the following standards and features: sostituire le sezioni con le informazioni sull'uso della periferica''''Nell'esempio di seguito c'è la descrizione dell'interfaccia HDMI''* Synchronous Audio Interface (SAI)* Pulse Density Modulated Microphone Interface (PDM)* Sony/Philips digital interface (SPDIF XCVR)* Medium Quality Sound (MQS) (MQS is used to generate medium quality audio to connect stereo speakers or headphones to a power amplifier)
=== Description ===
The Synchronous Audio interface available on AURA is based on xxxxx ''TBD:SOC name'' SoCInterface (SAI) supports 2 Tx lanes and 2 Rx lanes* 16-word TX/RX FIFO and up to 32 words per frame* One set of Tx clocks and frame syncThe SPDIF (Sony Philips Digital Interface) Transceiver supports raw capture mode that can save all the digital audio bits into audio buffer.
The Audio port supports PDM (Pulse Density Modulated Microphone Interface) module receives audio from a microphone. It includes the following standards and features:* Supports up to 8-microphones (4 lanes)* Supports frame synchronization
* High-Definition Multimedia Interface Specification, Version 1The MQS (Medium Quality Sound) is used to generate medium quality audio via a standard GPIO. It provides only simple audio reproduction.4a * Support for up Stereo speakers or headphones can be connected to 1080p at 60Hz HDTV display resolutions and up to QXGA graphic display resolutionsa power amplifier without an additional DAC chip. * Support for 4k x 2k and 3D video formats 2-channel, LSB-valid 16 bit, MSB shift-out first serial data (sdata)* Support for up to 16-bit Deep Color modesSignals over 10 kHz have worse THD+N values
