I just recently in the last couple of days tried the free compression utility called PeaZip. Use this link, it looks like there's a couple of 'questionable' sites claiming to be them but they aren't. This is the actual SourceForge site and is legit.
It will open .zipx files, but it will not create them. Very cool to know Bub, thanks.
I tried all the compression options it has available and I found that .arc worked the best on the file I tested.
I took a 32 Bit .wav file that was 46MB. The .arc format compressed it to 40MB. Everything else only took it down to 44/45MB. See note below
I use the Peazip 64 Bit Portable version. It runs from it's folder, you don't even have to install it.
It's also important to note that final zip compression is based on the content of the WAV file.
Let's take an example of a four minute song. Let's say that 24/48 the size of an exported mono WAV is ~25mb.
A full length export of the song verses a full length export of guitar part that is only played in choruses will yield very different end results as "white space" compresses a lot more even though the size of both files are the same.
Here is a real world example in 24/48. I have 5 live drum tracks. 4 in mono (Kick, snare, rack tom, floor tom) and one in stereo (overheads).
The overheads file size is 55,178 KB. Using Winzip .zip it compresses to 48,737 KB. Not very impressive but remember this is a track that is dense (the drums play thru the entire song). .zipx compressed to 35,810 KB.
But what about the toms tracks Bapu? I hear you. The toms have about 8 times where they play. Now, the drummer did me a favor and slip edited the toms tracks so that they are essentially less than a minute of material and over three minutes of white space. All other mono tracks are 27,591 KB. Tom1 compresses to 19,013 KB under .zip, but compresses to 13,897 KB under .zipx. See the difference?
The kick and snare files have also been slip edited to contain appropriate silence around the drums (essentially eliminating a lot of bleed, i.e. when toms are hit the kick track is not picking them up). This of them as a exported EZDrummer tracks where all bleeds are turned off.
So for these 5 tracks I have a total "file size" of 165,542 KB. Which as a .zip compresses to 128,766 KB, but as a .zipx compresses to 92,828 KB.
I'm not saying that Bub's example is better or worse but that one must put it in the context of the material being compressed to determine if there is file transfer time is to be saved by the use of .zip vs.zipx.
I'll have to get the product that Bub is referring to to try the .arc option because if it eeks out another 5% or more over .zipx in this exact example, I'll be all over that product.
Thanks for the tip Bub. I'll be back with my results.
