how to invert the samples of a audio signal

If you have column-oriented data and want to reverse the order of the samples, you need flipud () rather than fliplr () Try this. [y,fs]=audioread ('put your audio file path'); % This will give you audio samples is y (It should be in row vector). sound (y,fs); % Now listen it in correct ordered samples.

Why do you want to invert an audio signal? An inverted signal will sound the same as the original. Do you want to reverse the order of the samples? 1 Comment. Show Hide None. ramya on 21 Mar 2011.

How would I spectrally rotate/invert an audio signal ...

For real signals the unique span is f ∈ [ 0, f s / 2) or in fractional radian frequency f ∈ [ 0, π). So this is the OP's case with an audio file representing a real signal. The OP wants to rotate the spectrum such that f = 0 is translated to f = π (Equivalently half the sampling rate or f s / 2 .)

Since it's an audio signal, it doesn't much matter that the phases will be all messed up. You can't generally hear them anyway. Except for the flipping part, ARSS does the spectrogram creation and sound resynthesis. Otherwise, you can just take a FFT, invert the amplitudes of the components, and take the inverse FFT.
Invert Signal With Op Amp? - General Electronics - Arduino ...
https://forum.arduino.cc/t/invert-signal-with-op-amp/943859
Usual stomp pedal work at 9v DC. You bias your OpAmp at 4.5v (1/2vcc). Once in this state, the "bias" will act like a signal carrier for your AC signal. Your AC signal ground will then be the 1/2vcc bias. In this example, 4.5v. The AC signal will then be able to swing up and down around the Bias voltage.
Why would you invert the polarity on an audio track ...
https://www.futureproducers.com/forums/threads/why-would-you-invert-the-polarity-on-an-audio-track.366526/
Phase inversion (what I think you mean by polarity) is a simple solution to a common audio problem. Sometimes the signal on a particular track is out of phase with the rest of the music, leading it to sound thin and without body or presence. So, it becomes important to flip the phase of the signal 180 degrees.

Yes, this can be accomplished with a single transistor and resistor, but there are chips specifically designed to invert digital signals. Oddly enough, they are called inverters. Check out the 74HC04, for example. That gives you six separate inverters in a single 14 pin package.
