No more Audio examples in SDK v2.15.0 for EVKB-IMXRT1050?

[axel_wolf]

Hi,

V2.13.0 of the SDK for the RT1050-EVKB incudes an "audio_examples" section.

But this section is no longer included in V2.15.0 of the same SDK.

(See attached screen shots.)

Why is that?

Or am I missing something?

Thanks!

Regards,
Axel.

Hello Kerry,

Thanks for your reply!

Do you know if the "evkbimxrt1050_audio_maestro_playback" demo in the RT1050-EVKB SDK V2.13.0 actually works?

The reason I was looking for the latest version of the SDK / this demo was because the demo can't seem to see the MP3 files on the SD card...

The demo console output is as follows:

*********************************
Maestro audio playback demo start
*********************************

[APP_Main_Task] started

Copyright 2022 NXP
[APP_SDCARD_Task] start
[APP_Shell_Task] start

>> [APP_SDCARD_Task] SD card drive mounted
Available audio files:

(nothing...)

But as I said, the SD card has multiple short MP3 files located at the root directory.

Any ideas on why the demo can't seem to detect these files?

Thanks,
Axel.

Hi @axel_wolf ,

   As I know, you need to define which mp3 in the SD card you need to play.

  Please check my previous app demo document:

https://community.nxp.com/t5/i-MX-RT-Knowledge-Base/The-RT-speech-recognition-system-based-on-VIT-to...

  This demo, I put the mp3 data in the image directly, then play it.

  To the SD card method , the SDK can support it directly.

  You can try to just put one or two mp3 file in the root SDCARD path, then test it again.

As I also test it on my side with RT1060-EVK, that works OK.

Best Regards,

Kerry

Hello Kerry,

Thanks!

I got the files to play from SD card. (My mistake. The demo is fine.)

Hi @axel_wolf ,

  I check it internally!

  This audio_examples are really removed in the SDK2.15.0.

   If you want to use the SDK2.15.0, you can refer to the older version to create the demo, as the lib still in the middleware.

  Or you can use the SK2.14.0 demo.

Wish it helps you!

Best Regards,

Kerry

Hi @axel_wolf ,

 I also find the SDK2.15.0 lack the audio_demo for the maestro, but the maestro lib still in the package.

 If you need the audio_demo, I suggest you use the SDK2.14.0, as this version still contains the audio_demo.

 To the SDK2.15.0 lack the audio_demo, I will report it internally, as I find the middleware still have the maestro lib.

Best Regards,

Kerry
