Hey I was wondering if anyone could firstly clarify whether mp3 bitrate refers to either the total number of 'snapshots' (like frames per second) that make up an mp3 is or whether the 'fps' is constant and bitrate just effects the amount of data in each snapshot (thats my current guess, would seem to explain that low bit washout sound).
The question came up while I was inverting waves to make DIY acapellas and I was wondering purely for kicks, if you had a 320 bit mp3 and a 128 bit, couldn't you technically invert the 320 into the 128, and then combine that imperfect phase with the orignal 128 to essentially make it 320? This has no practical application I'm just curious whether I could do it.
Quick addendum, if bitrate does turn out to be related only to the amount of data, does that mean that the frequency rate controls the 'fps'?
DV1989:Right I know of course you can't just convert 128 to 320 and expect anything to happen, but inverting the 320 against the 128 (along with the rest of the procedure) would do something right? The extra data that the 320 would have that the 128 didn't would be left behind when the two cancelled each other out (what I meant by the imperfect phase) which you could then merge with the original 128 to fill in the gaps so to speak. Or am I misunderstanding how sound is stored as data?
I'm assuming that in a sample (now I know not to call it a frame, thanks)
is whatthe sound is reproduced with the right frequencies and respective amplitudes, is this correct? If I'm wrong about that then I absolutely agree it'd be impossible to succeed with my experiment.
