There is always a noise from the speakers at the end of the sound

[murarduino]

I did a simple loop playback test, including the startup in setup(), a total of 6 times, each time when the sound ends, there is always an electromagnetic noise from the speaker, and when the 6th playback ends, it also There will be. Not sure how to get rid of it.

include

include "SPIFFS.h"

include "AudioFileSourceSPIFFS.h"

include "AudioOutputI2S.h"

include "AudioOutputMixer.h"

include "AudioGeneratorWAV.h"

AudioGeneratorWAV wav[2]; AudioFileSourceSPIFFS file[2]; AudioOutputI2S out; AudioOutputMixer mixer; AudioOutputMixerStub *stub[2]; static int looptime;

void setup() { Serial.begin(115200); SPIFFS.begin(); delay(500); file[0] = new AudioFileSourceSPIFFS("/soundn.wav"); out = new AudioOutputI2S(); out->SetOutputModeMono(true); out->SetPinout(15, 13, 2); out->stop(); mixer = new AudioOutputMixer(32, out); stub[0] = mixer->NewInput(); stub[0]->SetGain(0.4); wav[0] = new AudioGeneratorWAV(); wav[0]->begin(file[0], stub[0]); Serial.printf("starting 1\n"); looptime =0; }

void loop() { static bool wav1end = true; if (wav[0]->isRunning()) { if (!wav[0]->loop()) { if (wav1end) { wav[0]->stop(); stub[0]->stop(); // delete wav[0]; // delete stub[0]; // delay(50); file[0] = new AudioFileSourceSPIFFS("/E233_CP_in.wav"); // stub[0] = mixer->NewInput(); // stub[0]->SetGain(0.4); wav[0] = new AudioGeneratorWAV(); wav[0]->begin(file[0], stub[0]); Serial.printf("continue 1\n"); looptime++; if (looptime>=5){ wav1end = false; looptime = 0; }

}

}

} }
