etree.org | shortn32.exe introduction

Shorten® (.shn) is an audio compression scheme that is used to compress audio (.wav) files losslessly. This means that after you decompress a Shorten file, everything that was in the original .wav is there. This is unlike MP3, in which the compression step throws away information that can never be recovered.

For distribution and archiving purposes, the Shorten (.shn) files themselves can also be burned onto a CD-R as data. One big advantage to archiving Shorten files is that you'll never have to deal with digital audio extraction (DAE) from an audio disc, which can sometimes produce clicks and other undesired artifacts.

The Shorten source code is the property of SoftSound Limited and has been made available to the general public for non-commercial use. The original SoftSound code has been extended by etree.org (most notably by the work of Wayne Steilau and Jason Jordan) to include "seek-tables" so that you can easily skip to any portion of a song in audio players like WinAmp and XMMS. The latest version of Shorten can always be found on the etree.org shnutils page or the FreshMeat project page.

For Windows users who wish to use a command line version of Shorten, you've come to the right place! When shortn32.exe is used along with the etree.org batch files, it's surprisingly robust and easy to use, minus all the bells and whistles of a graphical user interface.

etree.org | shortn32.exe installation

You will want to replace your existing shortn32.exe file.

  • Windows 95/98: Download shortn32.exe to c:\windows\command

  • Windows NT/2000: Download shortn32.exe to c:\winnt\system32
  • To find out what version of shortn32.exe you are currently using, open an MS-DOS window and type:

    shortn32 -h

    The version number will be at the top.


    If you downloaded the etree.org batch files for Windows, extract the three batch files (compress.bat, decompress.bat, makeskt.bat) to the directory: c:\windows\command


    etree.org | shortn32.exe usage, extracting

    To extract .shn files to .wav files (for burning to CD-R), open an MS-DOS window, go into the directory where the .shn files are located, and type the following:

    shortn32 -x [filename].shn [filename].wav

    You must insert the names of the .shn files [without the brackets]. Example:

    shortn32 -x ph94-06-26d1t01.shn ph94-06-26d1t01.wav

    The first file (.shn) is your input file, the last file (.wav) is your output file. You will have to repeat this process for each SHN file in the directory, unless you are using the etree.org batch files.


    If you're using the etree.org batch files, open an MS-DOS window and go to the directory you wish to extract from SHN to WAV. Type: "decompress" (without quotes). The batch file will prompt you what drive you wish to save the WAV files to.


    etree.org | shortn32.exe usage, compressing

    After making sure you have downloaded and copied shortn32.exe into the proper directory (see installation), open an MS-DOS window and go to the directory of the show you wish to compress into Shorten format.

    Type:

    shortn32 [filename].wav [filename].shn

    You must insert the names of the .shn files [without the brackets]. Example:

    shortn32 ph94-06-26d1t01.wav ph94-06-26d1t01.shn

    The first file (.wav) is your input file, the last file (.shn) is your output file. You will have to repeat this process for each file in the directory, unless you are using the etree.org batch files. Also, if you are using Shorten v3.0 or above, any SHN's you compress will have seek data embedded into the SHN file by default. Please encode the seek data to the Shorten files if you are creating/seeding a new show!


    If you're using the etree.org batch files, open an MS-DOS window and go to the directory you wish to convert to SHN. Type: "compress" (without quotes). The batch file will prompt you what drive you wish to save the Shorten files to.


    etree.org | shortn32.exe usage, creating seek

    If you have older SHN files that are not SHN v3 (seek) enabled, you can manually create seek data for these files!!! The easiest way to do this is by using the etree.org batch files.

    Open an MS-DOS window and go to the directory containing the SHN files you want to create seek files for.

    Type: "makeskt" (without quotes). The batch file will then create and save in that same directory a seek (.skt) file for each SHN file. It's that easy!


    etree.org | shortn32.exe etcetera

    When compressing new Shorten files, please remember to follow the etree.org naming scheme, and also make sure you are using the most recent version of Shorten!
