    Thanks Neurofun! I've moved the queue1.playBuffer() like this: sens_fusion_out = ((lis.x * GAIN_X) + (lis.y * GAIN_Y) + (lis.z * GAIN_Z)); Serial.print("OUTPUT: "); Serial.println(sens_fusion_out); ...

    It can be, but is something in between the raw data acquisition and the streaming. Because the plot looks to me quite accurate, is not losing samples. Thanks anyway for the quick answers and for the help man! I...

    I've tried as suggested but without luck. The I2C now is 400Khz and the sensor can read up to 5Khz. I've looked the output of the headphone jack with the oscilloscope and looks like that I have only the positive edge...

    I can ensure you that the analog accelerometer works fine and is audible, because the sound is vibration, is the same concept as the MEMS Mic. There are even studies about using the smartphone accellerometers as mics,...

    Sorry the image can lead to misunderstanding. My sensor is the "QUEUE1" because I'm getting the raw data and then use it for fill a buffer. The ADC is for something else, that is not used now. Here attached my...

    The vibration captured by an accellerometer is like a piezo signal generated by pickup or a microphone. I'm saying so because I've tried to "hear" an analog accelerometer (output through a level adapter and preamp). I...

    Is a LIS3DH accelerometer, I want to use it as a mic in a special application. For understand how it sounds I want to stream a single axis value out from the headphones through the Audio Shield.
