Question about file types

post #1 of 24
Thread Starter 
Well, Ive been working with learning to combine parts of videos and create one big one...but thats another story, now i need help on the audio side...

Which format is the best?

MP3
WAV
WMA

Why is it the best?

When using creative media source, it gives you these options to convert to...but under WAV it gives you options such as:

Channels: mono, stereo (ill assume stereo is the better)
Sample rate 800-90,000Hz (which would be best?)
Bits per sample: 8,16,24 (again ill assume 24 is best)

Now onto MP3 it gives these options:

Channels: mono, stereo
Encoding mode: Constant bitrate and variable bitrate (which is better and why?)
Audio quality: 32kbs to 320kbs (which is best or which is too much actually?)

Im guessing sample rate is the equivalent to audio quality? if I convert my music, what should I choose, why should I choose it?

When using creative media source, it gives you these options to convert to...but under WAV it gives you options such as:

Channels: mono, stereo (ill assume stereo is the better) <Stereo
Sample rate 800-90,000Hz (which would be best?)90,000Hz is better, but will result in larger file size. The higher the rate the better
Bits per sample: 8,16,24 (again ill assume 24 is best) <24 is best

Now onto MP3 it gives these options:

Channels: mono, stereo <Stereo
Encoding mode: Constant bitrate and variable bitrate (which is better and why?) <Constant is better, but variable will allow for better compression, You wouldn't hear much of a differnce between them
Audio quality: 32kbs to 320kbs (which is best or which is too much actually?)
<320 kbs is best, but will reuslt in larger file size. The high the rate the better.
Im guessing sample rate is the equivalent to audio quality? if I convert my music, what should I choose, why should I choose it?
So, if you have a lot of space, store them under WAV with little compression. For most people store them under MP3 with a good amount of compression. About the "audio quality" and "sample rate" you should, compress them but don't overly set them. I don't think the orginal has 90,000 Hz / 320kbs of quality

What source are you compiling from? (IE, how high is the quality of the master files?)

You're asking specifically what to use converting music from discs that you own into files to store on your computer using your X-Fi? Or are you asking in general?

No not at all, im asking what is the best quality sound and file . Im going to use the creative software to convert, so im asking in general, what is the best file type and best range and why.

They are all in a good bitrate MP3 right now, converting them wouldn't give you better quality.

Well, in general, you'll learn that once something is created, it doesn't help to "upsample" or "upconvert" because you cannot replace lost information. What I mean by that is, you might as well match the sampling rate with the original source because recording it at a higher rate is only going to increase the file size. With that said, Creative's Engineers swear that using the Crystalizer on your X-Fi can help restore lost information from the original recording, so it's worth playing with that. Overall though, it's a waste of disc space to record anything at a higher sampling rate that the original source. Think of it this way, if I'm giving you information at the rate of 2 words per minute, what good does it do you to write down 3 words per minute? (1 would simply be blank)

I use the crystalizer and I do notice a difference without it, but what do you mean by lost information? like lost parts of the track? Also, when and why should I convert audio tracks?

You should convert them to compress them better. I think of a song as a medium pizza... you take some cheese/toppings off when you convert it to a lower bitrate. Converting to a higher bitrrate is like selling your meduim pizza with less cheese as a large pizza. But the pizza is still the same. I just takes up more space (larger box). Taking off more toppings (lowering the bittrate) a little won't taste/sound with much of a differnce. Oh great now I'm hungray...
