+You can determine the volume with the help of the [VolumeOutput]() class:
+
+```C++
+
+#include "AudioTools.h"
+#include "AudioLibs/AudioKit.h"
+
+AudioInfo info(44100, 2, 16);
+AudioKitStream kit; // or use I2SStream
+VolumeOutput out;
+StreamCopy copier(out, kit); // copy kit to kit
+
+// Arduino Setup
+void setup(void) {

+    AudioLogger::instance().begin(Serial, AudioLogger::Warning);
+
+    // setup input
+    auto cfg = kit.defaultConfig(RX_MODE);
+    cfg.input_device = AUDIO_HAL_ADC_INPUT_LINE2; // input from microphone

+    // setup output
+    auto cfg_out = out.defaultConfig();
+    cfg_out.copyFrom(info);
+    out.begin(cfg_out);

+// Arduino loop - copy data
+void loop() {
+    copier.copy();
+
+    // Just print the max amplitude
+    Serial.print("Volume: ");
