WAV is a much bigger file as it contains all the information, an MP3 is a compressed file so is much smaller. If you want them to listen to in the Ciciv you need MP3 or WMA both of which can be created by Windows media player. Due the the road noise etc in a car 192kbs for an MP3 is adeqaute (you can do 320kbs which is called CD quality) but then you'll get less on a CD.

If you use a microphone or record from an external source like a turntable or cassette via an amplifier the likely format will be .WAV

This file will be massive compared to .CDA which is what goes onto CD's or the even more compressed .MP3 or .WMA

Programs like Nero will convert .WAV to .CDA when buring a normal CD (circa 20 tracks).

To convert to .MP3 for example you need to use Windows Media Player or the standalone CDex program.

Most MP3 players don't play WAV files - only MP3's.

Incase you want to use them on an MP3 player in the future - better just to burn them as MP3.

I believe he meant WMA files - not WAV

WMA and MP3 both set at a standard quality (eg. 128) the WMA file will be smaller.

I would recommend ripping to mp3, 320kbs its the best quality that is pretty much compatible with everything if you are not too worried about file size. mp3 is an old file format and not perfect but it is 99.999% compatible with all software and hardware, if you use your ripped music on different computer programs and hardware devices it should work with everything. Ripping all your music takes quite a lot of time, wma for example will not work with apple devices, you do not want to have to rip it all again just so that it is compatible with a new device. But it you only want to rip discs for your Civic wma will give you more songs per CD at the same bitrate as mp3.

As has been said, WAV files contain ALL the data recorded when the track was laid down, including the stuff we can't hear!! MP3's are smaller by about a factor of 12 due to the fact that encoding to MP3 removes the stuff we can't hear, then compares the two channels of sound for bits that are the same. These samey bits are only recorded once (not twice, once in each channel) and only the bits of sound that are in one channel only are kept otherwise. In this way the full stereo experience can be had without storing huge amounts of data.
It should be noted though, that due to the lack of sound below 20Hz (bottom of the human hearing range), MP3's tend to lack bass when played using a sub (which is designed to play sounds below the human range of hearing).
Hope that helps!!

MP3 can be upto 320k/bs sampling rate
WMA is upto 96 k/bs - but this is upto 168kb/s MP3 quality for a much smaller size, anything that over 168kbs you mite as well keep as MP3 and not convert it to WMA

if its AudioBooks, AudioCD's then WMA is fine

FYI, for the built in CD player in the Civs, MP3 and WMA are the supported formats.

P.S. WMA = Windows Media Audio. It's Microsoft's audio format.
MP3 is a common audio format used by MP3 players.

MP3 players do sometimes support WMA. Others support AAC instead which is Apple's format. iPods in particular of course.

WMA supports copy protection features. MP3 does not.

WMA and MP3 are "lossy" formats. That is when compressed they lose data to achieve such a high compression. In general the quality remains good, but depends on the bitrate. What rate you use to compress depends on how you're going to use it. In cars and on portable MP3 players with cheap headphones you can get away with lower bitrates.

And WAV, is a lossless format. If you rip a CD to WAV, it will be identical to the CD. There are compressed lossless formats too, like Flac, which is great for archiving CDs.



Anyway, difference between MP3 and WMA in terms of audio is not significant, other than I think you can achieve lower bitrates with WMA with the same quality results. MP3s however are more widely supported. MP3s have a downside of not inherently supporting gapless playback (i.e. when two tracks are played together, there should be no gap in for example a live music CD), though some encoders can get gapless playback support in, but the MP3 player needs to support it also. Sadly the Civic CD does not .

Cool thanks for that, interesting.
