What is xACT?
xACT stands for X Audio Compression Toolkit, an application that encodes and decodes FLAC, SHN, Monkey’s Audio, TTA, Wavpack, and Apple Lossless files. It also can encode these formats to MP3, AAC, or Opus, and do various other utility functions, in addition to a full set of shntool functions. Under the hood, xACT is a GUI based front end for the unix applications Shorten (3.6.1), shntool (3.0.10), Monkey's Audio Compressor (3.99, 3.100), flac (1.4.0), wavpack (5.5.0), TTA (3.4.1), Opus (libopus 1.1), cdda2wav 3.0 (with paranoia support), LAME (3.100), and aacplusenc (0.17.5). It also uses SoX ( 14.3.2), AtomicParsley (0.9.6), TagLib (1.9.1), MP4v2 (2.0.0), and rsync (3.1.3_31). It executes the basic commands of these applications and adds other features to speed up productivity in creation/use of etree.org standard filesets.
xACT started in 2003 as a simple graphical interface for the command line tool "shntool." I knew a few people who didn't want to use the command line, so I created a front end to let them use shntool (http://etree.org/shnutils/shntool/) without having to use Terminal. I started adding support for flac, shn, monkey's audio, etc. I thought only a few people would use it...
How do I install it?
Copy the xACT application to your hard drive.
How do I use it?
I'm sorry that this brief "how to" isn't nearly as complete as it should be. Someday I'll get around to making it more detailed. If you have any questions about how to use it, feel free to email me.
The basic functions of xACT are split into various tabs in the application. To convert files from a compressed format like FLAC, SHN, Monkey's Audio, Wavepack, Apple Lossless, etc to aiff or wav, you use the "Decode" tab. To convert files to these losslessly compressed formats, use the "Encode" tab. To make md5 checksums of files, verify md5 checksums or flac fingerprints, verify flac/wavpack/monkey's audio files and other functions that can help verify the sanity of files, use the "Checksum" tab. To use shntool specific functions (described in a section below), you use the "shntool" tab. To fix sector boundary errors in 16 bit audio files, use the "Fix SBE" tab. To edit tags in FLAC, AAC, Monkey's Audio, Wavpack, Apple Lossless or MP3 files, use the "Tags" tab. To use the batch rename function (described below), CD Extraction, add Replay Gain to FLAC files, remove emphasis from 16 bit audio files, or create a DVD-AUDIO disc image, use the "Util" tab (I didn't know where else to put these). To convert lossless formats into lossy MP3 or AAC files, use the "Lossy" tab. As of version 2.0, you should be able to do a combination of these things all at the same time. There is a preference you can set to control how many operations will do at the same time (max threads).
Decode tab: for decoding files to aiff or wav format. Note: xACT will not convert mp3 or aac files to any lossless format. Drag files onto the file list on the left or add files using the "Add" button. Choose output format to decode to and click "Decode." You can decode to the directory of the source files, and can choose to delete the original files after decoding.
Encode tab: For encoding files to lossless formats. Drag files onto the file list on the left or add files using the "Add" button. Choose the output format and format options if applicable.
Checksum tab: This tab can verify audio files (flac, wavpack, tta, ape), create checksum files (md5, ffp, st5), or verify checksum files (md5, ffp, st5). To verify audio files, add the files to the file list and select "Verify Audio Files." To create a checksum file, add the files to the file list and select "Create Checksum File." Choose the type of checksum file you want to create. To verify checksum file(s), add the file(s) to the file list and select "Verify Checksum File."
shntool tab: xACT can execute 10 different shntool options (fix has its own tab): len, info, join, split, cpm, cue, trim, pad, strip. The shntool documentation (http://etree.org/shnutils/shntool/support/doc/shntool.txt) describes each:
len Displays length, size and properties of PCM data
pad Pads CD quality files not aligned on sector boundaries
join Joins PCM data from multiple files into one
split Splits PCM data from one file into multiple files
cmp Compares PCM data in two files
cue Generates a CUE sheet or split points from a set of files
info Displays detailed information about PCM data
strip Strips extra RIFF chunks and/or writes canonical headers
trim Trims PCM silence from the ends of files
fix Fixes sector-boundary problems with CD-quality PCM data
How xACT uses these commands:
-For len, the user can either call the standard shnlen function, or show the length info parsed by disc or parsed as 1 fileset. The parsed output can be output with track names by clicking the "names" button and putting in the track names.
-Info is the standard shntool info output.
-Join offers 4 output formats for the joined file.
-Split offers 4 output formats and will prompt the user for an input file containing split points (for more info on split points, see the documentation for shntool). Note that for split, if multiple files are in the file list at the left of the tab, only the first is used.
-Cmp will call the standard cmp function to compare 2 audio files. Note that for cmp, the first 2 files in the file list will be used.
-Cue creates a CUE sheet for the files given.
-Trim will trim silence from the end of files. There are 4 options for output formats.
-Pad and Strip do exactly what the shntool documentation says they do
Fix SBE tab: Since fixing sector boundary errors is probably the most popular function of shntool, I thought that it deserved its own tab. There are 4 output options for the fixed files. When outputting to SHN, the user can choose to create 1 md5 or an md5 per disc, provided the files are named accordingly (ending with disc and track notation, like FOOBARd1t01). Note that the shntool I provided with xACT does not rename the fixed files with a -fixed suffix. I removed the -fixed suffix to avoid the user having to change the filename to remove the suffix later.
Util tab: kind of the "other stuff" tab with extra functionality people requested or I didn't know what else to do with
-xACT can do very basic batch file renaming. If the user feeds the util tab a list of files, it will sort them alphanumerically. When the execute button is clicked, the user will be prompted for a prefix. This prefix will be used for all the files, and a number (starting with 01 and incremented by 1 each time) will be appended after the prefix. If the files initially have an extension, the user will be asked whether to keep or ignore the extension. This feature can be useful when the user has a bunch of files that need to be renamed and ordered with a common prefix.
-xACT can do cd extraction via cd paranoia. For PC Users, this is kind of equivalent to EAC on a PC. It will do bit perfect extractions. Note: check out XLD if your main purpose is CD extraction. It's very good.
-xACT can add or remove replay-gain to flac files.
-xACT can author a DVD-Audio Disc image for playback in a DVD-Audio compatible player. The DVD-Audio spec has support for up to 9 different groups of tracks, but xACT only has support for 1 group right now. I may add in support for all 9 groups in the future. To make a DVD-Audio disc, drop either wav files or flac files onto the file list, select "DVD Audio Disc" and click "Execute." xACT will author the AUDIO_TS folder for the dvd and then create an .ISO image for burning to DVD. Note: The files in a DVD-Audio group must be of the same sample rate (xACT will scan the audio files to make sure of this). Also, creating a DVD-Audio disc requires approximately twice the disc space as the size of the disc. For example: if you're creating a 4GB disc, you need 8 GB free to create the disc; 4 gigs of temporary scratch space for the AUDIO_TS folder, and then 4 gigs for the disc image. xACT is using dvd-author to author the AUDIO_TS directory. Dave, Fabrice, Tim and Lee did excellent work on dvd-author (for free!), but it still may have issues with certain players or files.
Tags tab: xACT can write metadata tags for FLAC, MPEG-4 (AAC and Apple Lossless), MP3, APE, and WavPack files. You can tag individual files one at a time or tag a group of files at once. To select a file (or files), load the files into the list on the left, then click a file (or files) in the list. After selecting a file, enter tag info in the fields on the right. Clicking the "Write Tags" button will write the tags to the file. If multiple files have been selected at once, the tags will be written to all the files. Note that if you select more than 1 file at a time, you will not be able to put in Title or Track Number tags, since these are specific to an individual file.
Lossy tab: xACT can convert files to MP3 (using the LAME encoder) or AAC. LAME MP3 encoding can use a Constant Bit Rate (user defined) or Variable Bit Rate (V0-V9). AAC Encoding can use a user defined Constant Bit Rate, Average Bit Rate or Constrained Variable Bit Rate. xACT can also do true Variable Bit Rate AAC encoding (value between 0 and 127, with 127 being the highest).
Note: To clear out error rows on the status queue, right-click and choose from the menu that pops up.
xACT is freeware; see the "credits" directory for info on the tools and libraries it uses.

From the "FLAC/M4A Tags" tab, select "Load Tags From CUE sheet…" from the File menu and choose a cue sheet. xACT will attempt to parse the metadata from the file. Note: previous "Load track Names from file" was moved from the Edit menu to the File Menu.
-added ability to make DVD-Audio disc image from flac or wav files. note: the tool that authors the dvd-a data may picky about wav files having standard headers. If wavs don't work, try flac files.

-fixed bug where fingerprint file containing files with spaces in the name wouldn't verify correctly
-fixed bug where the output window would cause an error if closed and reopened
-reverted back to aqua from brushed metal
-fixed bug introduced by v1.10 of applescript where "delete original files" didn't work
-changed default extension for shntool md5 to .st5
-fixed bug that crashed the application under OS 10.4 when closing the trackname window (shnlen)
-downgraded flac to 1.1.1 because or Mac OS 10.2.x incompatibility
-fixed bug where unicode handling broke handling of ffp files
-upgraded flac to 1.1.2
-added a jaguar version of monkey's audio. xACT will now check the system version and call the panther version of monkey's audio for 10.3 and above. If the system is below 10.3, a different version will be called
-added "Write empty tags option for flac tags tab. if selected, the tags that are empty will be written as empty tags, otherwise the empty tags will not be written
-reversioned with "b" instead of "d"
-added DISCNUMBER flac tag
-changed tag handling to write tags even when value is "" (can be used to delete a tag)
-added a "current file" marker for the flac tags tab
-fixed bug in shntool join mode when choosing flac as output file
-changed implementation of rename input window
-removed flac libs from app
-changed how files are moved to trash when "delete originals" is checked. files are now moved to the trash of the volume they were on
-original files are also only deleted if encoding or decoding succeeded. if there's an error, nothing is moved to the trash
-modified how text is displayed in status panel
-packaged all required binaries/libraries WITHIN xACT. no more installation to usr/local/bin or /usr/local/lib. everything is IN the application.
-changed all references to String and text objects to Unicode text
-fixed bug when deleting original files after converting to flac
-included compiled sox 12.17.7, compiled without dependencies to ogg vorbis and lame. libvorbis and liblame removed from libraries included with xACT
-fixed bug in renaming of extracted tracks when more than 10 were extracted
-added renaming based on cddb names of extracted tracks from cds
-changed the way xACT finds the IOProviderClass for extracting via cdda2wav
-new installler needs root access (might go back to admin access. testing this)
-changed the way xACT deals with ALL files. it should be able to handle a forward slash ("/") in filenames now, though i won't guarantee it yet. hopefully i didn't break other things with this change
-added an option to extract files from CD to 1 file instead of separate files. note that the files will only go into 1 file if they are in order. ex: tracks 1 and 2 will go into 1 file. But if you want to extract tracks 1,2 and 4, they'll go into 1 file containing 1 and 2, and another file containing 4.
-bundled flac and metaflac 1.1.1 binaries
-changed the metaflac calls for flac tag writing to be consistent with flac 1.1.1
-fixed bug where fingerprints of filenames with special characters are handled correctly now
-added code to find the cd burner based on the output of the "ioreg" call for cd extraction
-added fading in/out of main window
-added support for cd extraction using cdda2wav and cd paranoia. very primitive
-reverted back to default flac level within the shntool flac module. xACT now uses the custom format module to allow the user to choose the flac level when fixing sector boundary errors
-the user can also choose the flac level when encoding from shn to flac directly
--added support for creating and checking the shntool md5
-started new Xcode project from scratch using existing code. Added drag and drop support for all of the file lists.
-fixed bug with pc formatted ffp files. xACT should be able to check them correctly now
-fixed bug with fingerprint file checking and filenames that contained special characters
-xACT will now output ffp files with extension .ffp.txt and will recognize the .ffp.txt extension as fingerprint files
-xACT will now output fingerprint files with filename:fingerprint (no space after the colon)
-initial version with util tab and simple batch file renaming. see notes above
-if the user adds SHN files to the Encode window and chooses to encode to flac, xACT will convert the SHN files to flac at flac level 8. the flac level slider will not matter here. the slider will still decide the level when encoding aiff or wav to flac
-shntool binary included with xACT is now modified so if the user chooses to fix and output to flac format, it defaults to level 8. as i said above, the slider will still decide the level when encoding aiff or wav to flac
-upgraded code and functionality for shntool 2.0
-added CUE option for shntool tab
-if the user chooses to fix files and output to the same format as input, xACT will not allow the user to overwrite original files. a different output directory must be chosen. note that this is only in the case where input and output formats are the same
-changed the fix command to never overwrite existing files
-back to brushed metal
-fixed weird interface bug relating to the "names" button
-upgraded monkey's audio to v3.99
-removed brushed metal texture to test out
-made the "names" button hidden on the shnlen option tab. it is only visible when the "len by disc" option is selected
-changed the track names input window
-fixed a bug on "shnfix" where the flac option was never called correctly
-added track name support to 2 shntool len options. Clicking the "names" button will allow you to enter in track names. If you choose either "len for fileset" or "len by disc," xACT will combine the tracknames and times together for output. When displayed in a fixed width font, these times will line up.
-yes, I know the button and track name windows are *really* ugly. That will change.
-added support for reading and writing FLAC metadata tags. You should be able to tab to each field and even to the filelist. tags supported:
TITLE (I usually put the song name)
ALBUM (for a live show, I usually put in the venue and date)
COMMENT (for a live show, I usually put in the source info)
COMPOSER (useful for classical music)
-fixed bug where a filename with multiple periods would be truncated when converting to flac
-fixed bug when doing "len by disc" with no disc 1 files
-new, separate installer package for binaries
-changed the way shns are decoded. shn > aiff is now *much* faster (due to the calling of shorten directly). shn > aiff creates a temporary wav which will be deleted automatically.
-better error messages on shorten decode
-added document icons for flac, ape, shn, md5, and ffp.
-fixed a bug where a fingerprint file would not show up on the fileList if it was dropped on the unopened application.
-added support for encoding aifc files to either shn or flac. aifc to ape does not work at this time
-the ENTER key should click the main buttons on each tab
--added .ape encoding. xACT will convert aiff files to wav before encoding to .ape. After the .ape file is created, the temp .wav file will be deleted.
--added .ape verification.
-upgraded sox to 12.17.4
-fixed a bug in encode so invalid file formats are now caught correctly
-added support for checking multiple md5 files or multiple flac fingerprint files at one time. note: checking a flac fingerprint file and md5 file at the same time doesn't work yet.
-changed so encode, decode and checksum lists are now sorted
-fixed a bug I was having on 10.3.1 and 10.3.2 where the app would unexpectedly quit when files were dropped onto the dock with certain tabs open.
-added support for a blank user password (on installation)
-24 bit ape to aiff and 24 bit aiff to ape attempts are caught and stopped correctly.
-changed the way ape decode is handled. I now call monkey's audio directly instead of telling shntool to convert to wav or aiff. if converting .ape to aiff, it will extract to a temporary wav first, then convert to aiff.
-added monkey's audio error codes.
-the main window can no longer be closed
-changed the layout of the encode tab to be less cluttered with the addition of .ape encoding
-parsed the output from both .flac and .ape verification to give a shorter, more concise message. xACT also parses the .ape error messages. Hopefully I didn't screw any messages up :)
-replaced md5sum binary with modified md5sum that can deal with DOS formatted digests. removed dos2unix since that was just a temp fix anyway.
-discovered a bug within v2.1 of md5sum (GNU texutils 2.1). DOS formatted md5 files would not check correctly with md5sum -c. Instead of changing md5sum, i just changed my code and submitted the bug to email@example.com
-xACT now bundles dos2unix to convert text files from DOS to unix
-improved error handling across the board
-added error log to display a summary of all errors (if any) when processing multiple files at one time
-added output for all fix calls
-added support for decoding of .ape Monkey's Audio files
-added shntool functions split, join, cmp
-added code to hide options that are not relevant to currently selected function
-apple+w now closes windows
-made the file lists larger and added scroll bars. changed other tabs to accomodate larger size of file lists
-removed "cancel" from all error dialog boxes, added timeout of 20 seconds
-added icons to all dialog boxes
-I am an idiot and forgot to include the sox binary with 1.0. somehow it got lost between 0.97 and 1.0. it's back now
-removed a dialog box from the checksum tab
- changed how md5's are made when created from encode or fix tab
-fixed bug where hitting the "add" button and then cancel didn't cancel
-fixed bug where encoding multiple times didn't clear the previous file list
-Added option to delete original files after an encode, decode, or fix. To be safe, the files aren't actually deleted, they are just moved to the trash.
0.95 (i don't want to call it 1.0 yet)
-added "show len for fileset" option to show just the times and total for a given fileset
-Modified the way the shntool calls were made so that files could be in different directories when calling "show len by fileset" and "show len by disc."
-Added padded zeros to "show len by fileset" and "show len by disc" output when necessary.
-added "show len by disc" option to create a skeleton info file for each disc. Filenames must denote disc. The app parses on the last 'd' in a file name, (so if a file has a 'd1' somewhere towards the end, it'll see that it's disc 1). This is the same string parsing as the "md5 by disc" option in the fixSBE tab.
-fixed bug in default actions
-Added default actions for .md5 and .ffp files
-Added FLAC fingerprint file verification.
-Added error checking to verification routines.
-more little fixes
-When the program is launched by dropping files on the icon, the following default actions are now implemented:
-If file is flac or shn, Decode Tab opened and files added
-If other (wav, aiff, aif, no file extension), Encode tab is opened and files added.
-"Add" button added to each tab. Multiple files can be selected
-the Shntool "len" and "info" options now output only the filename, and not the entire path.
-fixed many bugs dealing with md5 creation, naming of output files, the app hanging on certain operations, etc.
-Few bug fixes
-Update for Panther compatibility (including updated binaries)
-Added Brushed Metal to interface
-More bug fixes
-Output window now has a fixed width font
-"Clear" button added to each tab
