algo_stream error (AUD-2461)

[utkutpcgl]

I am not certainly sure but in this pipeline: microphone -> i2s_stream_read -> (input_buffer1) -> amr_encoder ->amr_decoder ->(input_buffer2) ->i2s_stream_write -> speaker I expect the record signal input buffer to be input_buffer1 and the reference signal's buffer to be input_buffer2. If I am wrong please correct me. This seemed logical to me by looking at the following diagram:

When I tried to build the project with algo stream added I face the following error:

As far as I understand libesp_audio_processor.a has a reference to esp_kiss_fftr in noise suppression related functions in the ns_core file. I guess I faced a bug. I would be glad if you could help.

I use:

Latest adf version idf version 4.1 Windows idf command prompt esp32_lyrat board.

Have a nice day.

Hi, @utkutpcgl, did you get the example code already? Do you combine algorithm stream with pipeline? Regards

[utkutpcgl]

Hi, I could not find the example yet. Yes, I think we have to combine it with the pipeline as an element. Best wishes.

[utkutpcgl]

The example is available.

I tried to flash LyraT with the structure given in the example code again, however, there is still the same error:

It has been 20 days since I reported this error, so, it would be nice at least to see a response. Thanks in advance.

[jason-mao]

@utkutpcgl Sorry for missing, would you please provide your IDF version and ADF commit or version?

[utkutpcgl]

I use latest esp-adf and esp-idf 4.1. Also, I work on cmd-esp-idf. Thanks @jason-mao , I understand you have not much time.

[jason-mao]

@utkutpcgl There is a quick fixes as follow.

cd $ADF_PATH/components/esp-sr/
git checkout master
git pull

Then modify the CMakeLists.txt, Add add_prebuilt_library(esp_audio_processor "${CMAKE_CURRENT_SOURCE_DIR}/acoustic_algorithm/libesp_audio_processor.a" PRIV_REQUIRES esp-sr) behind
https://github.com/espressif/esp-sr/blob/eec128886f882f4bd446eb53588c16858a68acb1/CMakeLists.txt#L23. ,such as

[utkutpcgl]

Thanks for the fast response, I will share the results.

[utkutpcgl]

It works fine as far as I have tested. Thanks!

[Patsjemoe]

Hi, Did you use it as it is, or did you make any changes? I am trying to implement it in VOIP, but am still struggling due to unclarities in description of multi input/output ringbuffers regards Ludo
