http://www.staredit.net/topic/5294/WAV compression could also mean the compression inside of an MPQ archive. WAV files can also have unnecessary header information.
An alternate method of "compressing" WAV files(that I use), is manually halve the frequency using a hex editor, and "speeding up" the result through Sound Recorder. (Also works from going stereo to mono)
Another thing you could do with a hex editor is:
A) Remove any appended data left by some programs.
B) Remove the unnecessary "fact" header.
C) Resize the original header to 0x10.
Also, WAV files will compress better in MPQ archives if they are 16-bit and imported at maximum audio compression.
A good example of crap WAV files are in the map "Lost City". They have extended headers, appended data, and everything you don't want in a WAV.
So, starting with the original quality WAV, perform my above steps, and you should have minimal quality loss.
.WAVs are uncompressed and compressing them will change the file completely...
You can change the size of your .WAV by changing the sample rate and if its mono/stereo..
Doesn't sound like what you're doing is compressing, just altering the file..
None.
Altering the file to have a smaller size is compressing it, Kellimus.

How does Hexediting == Compression?
From what it sounds like to me, he just cuts off the information associated with the .WAV file which would just cut some of the bytage off... That's not converting it to a compressed file such as .mp3

Compression is making the file smaller, removing bytes from the file makes it smaller. You don't need to use a compression algorithm to make a file smaller or to be called a compressed file.

.mp3 is a different file format, not a smaller .wav, oh, and you're an idiot.
None.
Its just taking off unneccessary information to lower filesize. Sort of like a box. Remove the box to get the good stuff inside. (Or the box...)
None.
The way he's compressing it, at least with the speeding up part, will give lower quality, Kellimus, however, it still compresses it nicely for how it sounds.
None.

Why, because I don't agree with you? Doesn't make me an idiot.
And you're right. .mp3 IS a different file format but it is essentially a compressed .WAV file you twit. I deal with music producers quite a daily basis and they throw around .WAVs because they're uncompressed and the highest quality sound you can get. They give .mp3 files after they are done because they're compressed files with a usually unnoticeable change in quality (well, if its low-quality .mp3 you can tell) so they can give people five minute songs at 5MB instead of 500MB.
.mp3 is a compressed sound file (usually converted from .WAV files) so whose the idiot??
None.
Regardless, you didn't know what compression was, so you're still an idiot.

But we cant use .mp3 in our maps. Why else would we use .wav files?

I know what compression is you moron, Hexediting a .WAV file != Compression.
Its cutting down some bytes (according to the topic creator its his method of 'compression' [take notice of the quotes]) of unneeded information off of the .WAV to make it a smaller size.
That's not compression.
None.
Data compression is by definition:
A technique in information technology by which the same amount of data is transmitted by using a smaller number of bits; for example, by replacing a string of ten repeated digits with a command to repeat the digit ten times.
So, reducing the number of bytes (and therefore bits) in a file is compression.

He doesn't replace any information, he erases. He's cutting out the information, not re-arranging it.
Therefore its not compression. He didn't say it was compression either, he used ' 's around the word.

He didn't say anything about replacing. It is the same WAV with a smaller amount of bits to represent it, which IS compression.
And you don't know why Heinermann put quotes around the word, you are just putting words in his mouth. I'm GUESSING he put them there because its such a small difference and doesn't use a compression algorithm, but it is still compression, but maybe he'll clear that up.

Reducing the quality to lower the file size is still a compression, even if it is the same file format as the original. It's a lossy compression. Even if compression wasn't the right term, I'll use it anyway, and I don't care what anyone has to say about it.
Kellimus, you still troll here to pass time?
Compressing in quotes in the original post is referring to changing the quality of the WAV.

Look at the above bold characters. Didn't put any words in his mouth at all.

You don't have to go Hexedit to lower the quality of .WAVs, you just need to change the sampling rate and there you go. So you're just deleting information from the .WAV
How is that

Nah I don't troll. Just speak the truth

There is a distinct difference in quality when hex editing and "speeding up" and when just changing the sampling rate.
Also, can you reference the source for your definition?

Sampling rate doesn't speed anything up or slow anything down, it highers or lowers the quality of the .WAV
A .WAV with a higher sampling rate of lets say 44,000Khz compared to one that's 28,000Khz.
The later will be of lesser quality.

Did you even read what I said or can you just not comprehend? Read the bolded+underlined part...

You don't HAVE to, but guess what, you can! Which is compression because you are making the file size smaller! Interesting no?
