recently i work on ws2811 (Neo pixel addressable LED)
i just taught that how to make animation in those leds?
after searching on web>> arduino & other controllers are used for drive them.
some controllers are really good with PC Support.(hope you understand what i'm trying to explain)
if not, here it is >> make animation in PC with support of Graphical UI and arrangement of LEDs,like Number of LEDs how to Loop them ETC...
after all export those complied file in flash drive, insert flash drive in controllers USB hub & that's it.
but one Tickle in my mind, every time when i want to drive my neo-pixels i need those controllers.
soo here is HACK i record controllers single pin's data as audio in my flash drive, & play through
cheap mp3 player, i have two options (Right-Left) i record on right_chennal, so as define number of led
& effects >> works 100% accurate.
but main question is >> can i store(like oscilloscope) multiple channels data in audio format ?

That's an interesting approach.

I don't think the signal will remain the same if converted to an MP3 file as the lossy compression will probably remove some detail. A lossless audio format might be better as long as the signal frequency does not go above about half of the audio frequency (see Nyquist).
If you go old school with an audio cassette you get a left and right channel and 2 directions to the tape that's 4 channels, you can only use 2 at a time. If regular speed doesn't work you can always try speeding up the tape as you record.
