Hi
AS analogue audio is transferred as a Voltage vs Time signal, the oscilloscope is a good way to examine that audio waveform in real time.

That being said, it is a visual tool and requires your interpretation (search on line for how to video's etc).
The strongest reason for a DIY'r to get one is that you can diagnose the single largest thing that limits dynamics.

While everyone knows what clipping is, few know that when it is very short in duration, you can't hear it as a flaw or "clipping" but what it does do is limit the dynamics.

If you get a 10 x probe and look at the signal going to your speaker (and have the sweep rate and trigger right) and if you see on peaks that the top if the wave is flat, even one, you have clipping.

This can be from the amplifier but also any other part of the chain as the more complicated the system gets, the more chance to have an incorrect gain structure (resulting in one stage clipping far before the other stages).
Best,
Tom
