TX2 and Xavier NX Audio Codecs

Hi,

I’m currently using both a speaker and a microphone connected to a Xavier NX via I2S. I would like to know exactly which audio codecs are available on the Xavier NX and TX2 NX and if they are Hardware codecs. I didn’t find much information in the datasheets, so I am asking here.

Thank you!

Hi alexisguiter,

If you are asking about audio compression formats supported, there are no HW codecs on NX.

Please let us know if there is any specific soft audio codec you are looking for?

Thanks,
Sharad

Hi,

I’m talking about the ability to record raw audio (or encoder to .wav/.mp3) using an external microphone and sending it to a buffer.

In the near future I also plan to write some C/C++ applications using ALSA. Doesn’t this page from Nvidia documentation mention audio acceleration?

If you are asking about Audio HW accelerators (not compression formats/codecs) : there are many accelerators available in NX and details can be found at here.

I encourage you to go through the BSP document and share specific queries.

Thanks,
Sharad
