can someone have a look at this spectrogram / waveform is this music or noise?  digital download 24/88 sounds fine however how would i know if the high frequencies are music or noise?
Oh I don’t know...just listen, maybe?
Many times I have asked people, do you enjoy looking at graphs or listening to music? Usually sarcastically. Never actually had anyone take me up on it. So congratulations are in order. I guess.
I don't hear any noise.
The main thing I learned, its impossible to last 5 minutes playing this game.
Above ~22KHz is most likely noise... Could be introduced by re-sampling/upscaling/noise shaping, pushing noise up and out of the audible range (is there life above 20KHz?)... Do you know the provenance of this recording?
