The main difference between EAC and other audio grabbers is that EAC uses a new technology that performs DAE almost perfectly. If there are any errors that canot be corrected, EAC will report the time position the possible flaw occurred, so you can easily correct the flaw.

For the most recent software and documentation updates, please visit the official EAC website.

etree.org | EAC download

eac09pb7.zip - 715KB v0.9 prebeta 7 Released: 10/11/00
v0.9 prebeta 7 should only be downloaded & used by experienced users! If you encounter problems with this version you should step back to the version below

eac085b.zip - 493KB v0.85 beta 4 Released: 2/9/99

etree.org | EAC documentation

To set up EAC to automatically create SHN's of an extracted disc:
  • Go to EAC > Compression Options > "External Compression" Tab
  • Check "use external program for compression," then pick Shorten from the dropdown list.
  • Browse to your shortn32.exe file (Should be c:\windows\command for Windows 95/98 users; c:\winnt\system32 for Windows NT/2000 users).
  • Check the "delete WAV after compression" if you want.
Now, when you extract tracks, they will each be encoded to Shorten. Make sure you review the EAC error log when making SHN's with DAE to make sure they don't contain errors.

Thanks to Jeremy Clark for this information!

Additional note for Windows XP users!

You will also need to go to the location of shortn32.exe, and follow these directions:

* Right-click on the shortn32.exe

* Click properties

* Click the Compatibility tab

* Click the checkbox for "Run this program in compatibility mode for:

* In the pulldown menu, choose "Windows 2000"

* Apply your changes

For additional tips on setting up EAC, please go to the Official EAC Documentation Page, Dick's EAC page, Elite DAE, or The Coaster Factory's EAC Pages.

Thanks to André Wiethoff, the author of Exact Audio Copy. Please do not email the author for questions of usage, go to the EAC website and read the documentation!

Re: The Validity of MD5 Checksums

eac came with spectral and frequency analysis (sa, fa) tools which the community found useful for spotting lossy sources. semi-useful, I should say. there is a terrible haze from a mirroring effect of some kind that clouds everything. fa also not good. cool edit pro aka adobe audition was the best, but it is not free. these days spek is preferred for spectral analysis. I think audacity frequency analysis is fine, just that doesn't inform us enough to make a true judgement.

this ancient guide we used to refer to in the stg days from audiohub.org is still on archive.org. check here to see more info about new software and methods we use.

Re: The Validity of MD5 Checksums

indeed!

sit back and I will tell you all about the good the bad and the ugly software we used to use. some of it is better than anything we have now, and largely forgotten. some of it was crap.

here's an excellent freeware from 2000, still works perfectly on win10 straight out of the box. now that's a software!

--------

back at sharingthegroove.org (RIP 2004) every "is this FLAC mp3-sourced?" thread was full of people looking for clues in frequency analysis graphs. "could you change x setting and post another screencap, please?" was the order of the day. in the end, fa helped a little, good sa solved the puzzle.

audacity can do a fine frequency analysis, sure, but there was another fa freeware soft that was strongly preferred by all: AnalFreq v1.8

find it here:

dead original homepage (not on archive.org)

I still laugh remembering U2Lynne telling ppl to download this prog, "yes, it's really called that!"

Re: The Validity of MD5 Checksums

for me, win98se. once you've got all the drivers in place, it is snappy fast compared to win10. especially windows explorer, ugh, 2020 and my computer is more sluggish than 1998.

--------

2002-08-26 SpectraScope v2.7 shareware released for $30. Should have been called 'AnalScope' I would pay $30 for that.

seriously, thx to Christopher Brown wherever he is for freeware AnalFreq. you can tell how amazing this program is when you try it.

bittorrent guide by slyck, offline since early 2020.

BitTorrent Intro

BitTorrent is a P2P system that makes transfering large files (or groups of files) amongst a large group of people easy, fast and efficient. The BitTorrent network is set up in a way that is a little different than a normal P2P network. With this network, you really don't do any searching for files that the other users have using the client as you would with traditional clients. Rather, you go to websites that have lists of recently released files.
The websites listing the torrents are called indexing sites and have become very popular. Their popularity has come at a cost however, with the MPAA and law enforcement agencies shutting them down. There are no shortage of sites to go to so long as you know which are currently being used, as they come and go so quickly these days. The files that you get all come as a package called an archive, and to receive them you must first get a .torrent file (don't worry, that's what you went to these websites for). Once you have downloaded the .torrent file, your BitTorrent client will kick in and connect to a managing computer that then connects you to others who have the files.
BitTorrent is a P2P system that uses a central location to manage users' downloads. The central location is a tracker that is connected to when you download and launch a .torrent file. The tracker keeps track of all the people who have the file (both partially and completely) and connects users to each other for downloading and uploading.
The BitTorrent network is impressive mostly for the speed and reliability with which you get files that have been recently released. As long as a .torrent file has enough people sharing then you can be assured that it will start quickly and maintain a good download speed. Most indexing sites have a system of listing the number of Seeders and Leechers for a particular archive.

What is a seeder?
A seed(er) is a client on the BT network that has a complete copy of a particular archive. For any archive to work, there must be at least one seed to download from originally. Sometimes under certain circumstances, there may be no one seeder but enough people with all the parts to make up the whole archive, this is called a distributed copy. It is HIGHLY recommended that once you have gotten an archive you leave the BT client running for at least the amount of time that it took you to download the archive to help ensure that others will also be able to get it. Share and Share alike!

What is a leecher?
A leech(er) is a client on the BT network that does not have a complete copy of a particular archive yet. When any new client begins downloading an archive, they are a leecher until they have finished downloading the entire archive and then become a seeder. The name 'leecher' here is an unfortunate use that has become too commonly used even though it is really not applicable to what the meaning is. A leecher normally means someone who downloads without uploading (takes but does not give.) But here, a leecher is part of the network and is uploading as well, many times more KB than they download. But hey, it's worth the new meaning once you appreciate the vast resources that BT brings to you.

What is a .torrent file?
To download something with BitTorrent, you must have a .torrent file. This file contains in it a location that tells the BitTorrent client where to go to find the tracker that manages the uploading and downloading of the archive. An archive is a complete set for downloading which may include one file or many files. The one .torrent file contains the archive information also. To download on this network it is simply a matter of clicking on the .torrent file in your web browser, then the BitTorrent client kicks in and asks where you'd like to save the archive. That's it, from there you just sit back and watch the client work it's magic.

Re: The Validity of MD5 Checksums

some countries have standards for stereo microphone placement, and if you violate these national policies you lose your job! there is NOS (Germany), RAI (Italy), some others probably, and then there is ORTF (France). Every taper in the world seems to prefer this calculable re-creation of the French airwaves.

while Alan Blumlein recommended only near-coincident techniques, here Michael Williams explores stereo pairs with alternative spacing and angles, presented at the 75th convention of the Audio Engineering Society at Nogent-sur-Marne, France 1984-03-27 -- 1984-30-30
https://microphone-data.com/media/fi...%20zoom-10.pdf

at Michael's retro 90s site you can still download many AES white papers free without the usual paywall. these are 'retro' 80s versions, made on a typewriter with hand-drawn graphs then copied on a machine that stinks of chemicals, including 'the stereoscopic zoom' first print. the upper-right link contains a nice online general purpose guide to stereo microphone theory. following Michael's advice you can hook up way too many microphones and get the mathematics straight.

Re: The Validity of MD5 Checksums

an in-depth article about Blumlein M/S Stereo, 1986
https://www.audiosignal.co.uk/Resour...uffling_A4.pdf

I don't think it is realistic sound at all, this is used a lot in television and certain led zeppelin songs. not very useful to tapers, but worth a look as its Blumlein's 'other' stereo configuration, and its brilliant.
