high resolution USB Audio class

[yo_ku_]

I found a dev_audio_speaker of USB in the sample code of LPC54018 on MCU Xpresso IDE.
This Sample seems to be compatible with USB AUDIO CLASS 2.0.
Is the LPC54018 capable of supporting high-resolution Audio such as 24bit192kHz?
Of course, the Audio Codec (DAC) to be connected will be replaced with one that supports high-resolution audio.

Hello yo_ku_,

The LPC54018 should be capable of supporting 24-bit 192kHz, and this format is included in the fsl_codec_common.h header. You would need to use a compatible codec, as you mentioned.

The examples are USB Audio Class 2.0 compatible, but these are very limited and used as proof of concept. Please refer to the documentation on each of the examples to see how they are implemented.

I hope that this information helps!
