Re: Seeking a Rough Quality Comparison

JM Casey

I believe that my answer is the most objective one .. not to sound pompous,
but while I hardly use .m4a files and don't know a lot about them
specifically, I have done research on stuff like this and I believe using a
slightly higher bitrate than the original will get you best possible results
(not an improvement though mind you, you'll never get that).
128kBPS is not at all CD quality by the way, as has already been said. It's
actually quite a poor transfer. 256k is *close* to CD quality; 320 would be
best if you really want things to sound as close to original as possible. I
sometimes wonder though if at that point you may as well just use lossless.

While what you say makes sense, I'm not sure that is really what is being
asked but I could be wrong. We know that a 128KBPS MP3 is said to be
approximately CD quality, so 160KBPS would presumably be a little better.
We might disagree whether that is truly better than a CD, but I think we
would all agree that 160KBPS is better sounding that 32 or 64KBPS stereo.
So where does 160KBPS MP3 settings fit into M4A settings to get
approximately the same quality? There may not be an answer we could
absolutely agree on, but one would think there would be some approximate
corresponding setting.

Best regards,

This question is very subjective. This particular question is actually
entirely dependent upon you, the one who is actually going to be the one
doing the listening because as you already know, how it sounds to one is not
going to necessarily sound the same to the next. Sound, taste, feel, smell,
etc etc etc.

We all have separate senses which I know you are well aware of. What can be
a perfect amount to one, may be a little too much for the next or maybe a
little too little so on and so forth. So it's up to you the actual listener
to determine these specifics because you are never going to hear anything in
this world through anybody else's ears. No different than you are not ever
going to eat anything with anybody else's mouth and as you know, we can go
on and on and on with the various examples, but it is literally up to each
of us to determine this, that, and the other for our various likes and

Hi List.

Can anyone in the know provide me with a rough idea of what the equivalent
kbs would be for a m4a file when compared to a 160 mp3 version?

I probably haven't explained that very well.

If I have a file saved at 96kbs m4a, what would a rough approximation to
this be for an mp3 file? Would it be 128kbs or 160 kbs for example?

I've tried finding some kind of guide on the web, but haven't been able to
turn up anything that I can readily see as a comparison.

Thanks to anyone with any knowledge who can help me out with this one!
