But if you upsample 44100 to 88200, you won't hear any difference (I am confident 95%)

Pure upsampling does not make it sound any better
MG
ok
MG
would an algorithm applicable for one bit depth be applicable to another bit depth without changes being made to the algorithm?
MG
for example, unsigned 8 bit, signed 16 bit, and 32 float
I
Generally a good practice is to convert source material to floating point format and work with this

Read that message again
I
This is done on purpose in order to make a universal algorithm that work with floating point numbers
I
You separate your algo from any "preparator" that will take any desired bit depth and convert it to 32-float or 64-double
MG
so that would also make it dependant of how well you can decode and recode source data such that there is no change in quality? for example, assuming you are capableof playing OGG format audio, 8 bit OGG to 32-float PCM then back to 8 bit OGG with no change in original quality ?
MG
(or possibly just 8 bit OGG to 32-float PCM with no loss in quality if you are able to also play PCM format audio)

Decoding and encoding are also the points of loss yes
I
You can minimize the loss, but you will never get it to 0% (if you convert the data)
MG
ok
MG
so would resampling it directly provide higher quality than converting then resampling?
MG
or would that not matter since all data would be eventually converted into PCM either externally or internally via android os for playback depending on what formats the hardware supports
MG
or would the difference be unnotaccible unless on extreme resamples like 8khz to 192khz

I think I am going to kill you
