sound overload when connecting an equalizer

Postby Dimych » Thu Oct 22, 2020 10:30 am

Hi,

I use the http_stream->mp3_decoder->equalizer->i2s_out stream chain.
The sound is very overloaded, there is no reaction to the settings band gain equalizer.
If you exclude the equalizer stream, then everything is ok.
What could be the problem?

Windows
ESP-IDF v4.2-beta1-86-gdddcc2ede-dirty
ESP-ADF v2.1-67-gbafffc5-dirty
I tried setting the bands from -50db to 0db. No change.

Re: sound overload when connecting an equalizer

Postby Dimych » Thu Oct 22, 2020 4:55 pm

I was able to figure out that the equalizer settings are not applied at initialization.
If you adjust the equalizer after starting playback, it works. But in most cases it throws an error ...
Is there a workaround? :cry:

Code: Select all

        audio_element_set_uri(http_reader, uri);    
        audio_pipeline_run(pipeline[SOURCE_MUSIC]);
        //equalizer_t *eq = (equalizer_t *)audio_element_getdata(equalizer);
        int gain[] = { -13, -13, -13, -13, -13, 10, 20, 20, 30, 30, -13, -13, -13, -13, -13, 10, 20, 20, 30, 30};
        for (uint8_t i = 0; i < 20; i++) {
            equalizer_set_gain_info(equalizer, i, gain[i], false);
            //eq->set_gain[i] = gain[i];
        }
        //eq->gain_flag = 1;
