When SoundNote[] is evaluated, I expect the audio both channels to be the same but they are different.

The code

a = Audio@Sound[SoundNote[]];
data = AudioData@a;
Periodogram[data, SampleRate -> QuantityMagnitude@AudioSampleRate@a]

yields

enter image description here

This shows two plots, where one corresponds to the right and other to the left channel.

What would be the reason behind making SoundNote generate a different output for each audio channel?
