SoundNote is evaluated, I expect the audio both channels to be the same but they are different.
a = Audio@Sound[SoundNote]; data = AudioData@a; Periodogram[data, SampleRate -> QuantityMagnitude@AudioSampleRate@a]
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?
