Improved Palabra 2.0

Palabra 2.0 with many improvements is available for download!
Recently I became a frequent user of my own Palabra as am I going to go to Japan and I need to refresh my Japanese language skills. While using it I found a few bugs or irritating behaviours. I also redesigned the popup screen to get a nice look. The application is more mature now and better adjusted for Windows 7. Possibly Windows 8 as well, but I since I am not a big fan of this new OS I haven’t tested it there. Therefore if you find any issues please let me know.
The latest version is available in Palabra section as usually. Feel free to use it. I would be happy to get you feedback or any lessons you created and wish to share with others.
See available lessons in Palabra resources section.

A few improvements to AsfBin

What's in this version?

• Improved precision of resulting file duration when joining many files together.
• Added support for UTF-8 text files when importing markers, scripts and attributes. With this improvement any languages like e.g. Japanese, Arabic can be used when adding markers, scripts or when setting file attributes.
• AsfBin can fix files that were having incorrect entries in the metadata object preventing it from playing by major video players.

The latest 1.8.3.934 AsfBin command line tool can be found as usually here.
The window version is going to be released shortly.

New asfbin without the "Human Test"

I have received a critial feedback on the "human test" I had introduced in the previous vesion of Asfbin to mitigate some cases of it being overused as a slave worker to some so called "GUI" tools. This was mostly around cases when legitimate non-commecial users had problems with running in batch processing mode.
Therefore I decided to get rid of this test completely.
This version also contains a fix for the out-of-memory issue when processing files over 2GB in size having a script command stream in it.
The new 1.8.2.903 AsfBin release can be found in the AsfBin section.

[12/20/2010]

Palabra! Learn while working. Its easy!

Palabra - absolutely fresh software free for download.
This time I would like to share with you a software, which I was looking for a long time but as usually there wasn't any that would fulfill my high requirements. Palabra means a word in spanish... and sounds nicely :) But apart from this it is why Palabra was mainly created for - learning words. Currently you can create any lesson you wish using a flexible editor.
In short, Palabra is meant to periodical asking you from questions included in the lesson meantime gathering marks for answers and determining a schema for subsequent repetitions to make learning process as effective as possible.

What distinguish Palabra among other similar programs is maximum simplicity of use, possibility to edit a lesson, make corrections on each stage of its learning. Simple example - only 3 key presses are required to learn one question: Enter for showing an answer, key 2,3,4 or 5 to mark yourself and finally Enter for skipping to a next question.

On the beginning you will find on my web pages sample Spain lessons. Next I am planning on putting some Japanese lessons for you. I hope, that the number of lessons will be growing fast, thanks to you as well. I am opened for all your opinions about this new software but now I am pleased to invitite you to the Palabra section, where you can download and try the first public release.

[3/29/2008]

New software upcomming

Long time no news on my site. I was a little busy with my office works as well with improving asfbin. But in the meantime I have written a brand new software supporting learning foreign languages (but can support any other learning topic as well). Please visit my site soon.

AsfBin 1.6.1 was made public

AsfBin version 1.6.1 is ready for download!

This version corrects some minor bugs that got to the last release. Detailed description can be found in What's New section as well as in the whatsnew.txt file included in this release. Follow this link in order to download the latest version.

[2/22/2007]

AsfBin Version 1.6 is ready!

Finally the buggy jitter correction algorithm implemented since version 9 in MS Windows Media Players was defeated!
It was possible thanks to adding to AsfBin an audio decompression feature and thus making real sample duration measurement possible.
The old algorithm which was after all giving decent results was replaced by a new advanced junction optimization algorithm resulting in smooth connections between audio tracks without any unnecessary gaps. Of course, since audio samples are not reencoded a single pop sound can be heard where the files are joined together.

A new AsfBin has also many other features. Error correction engine was made so robust it can correct almost all cases submitted to me last time.
To download the latest version, please proceed to AsfBin download section.

[11/15/2006]

AsfBin 1.6.1 was made public

Yes! HostItNow company which is hosting my site got visitors! They changed my site to some garbage filled with some dangerous stuff. Thanks to one of my users who reported that my site is down I noticed that HostItNow.com became HostItLater.com. Unfortunately nobody from their staff were gracious enough to take proper steps in order to solve that problem.

Anyway, it forced me to switch to a new hosting company and a new site design... at last!!!

I think that the following days will be abound with lots of corrections and making changes. Japanese an Polish versions will be blocked for a while. Please, forgive me in advance for some site errors and inconsistencies.

[4/19/2006]

AsfBin 1.6.1 was made public

[12/9/2005]

Not only bug fixes - AsfBin 1.1 is out!

It was high time to release a new version of AsfBin, because quite a long time ago people were reporting problems with repairing some ASF files.
The fix was ready but I was in the meantime of making a lot of changes in engine. Also this time there are plenty of new features many people were awaiting with highest anticipation:

• saving segments to a separate ASF files,
• inverting selection, so you can easily point the fragment to be deleted,
• adding markers and commands (at last!),
• delaying selected streams (not necessarily audio streams),
• printing out information on key frames location,
• control over the type of indexing,
• cutting fragments adjusted precisely to key frames locations,
• plus a lot of improvements in the parsing engine.

Go to the AsfBin download section section to get the latest version.

This is a very early version containing basic functionality but still, it is based on the latest version of asfbin - this time this is version 1.0.3.418, which is also made available in the AsfBin download section.
This version fixes several bugs reported by people and has significantly improved reliability and resistance to more severe ASF file errors including data packet and header errors. Indices are ignored as usually.

[6/8/2005]

AsfBin problems with Windows 9x fixed

Unfortunately I didn't have enough time to test AsfBin "strongly" under any Windows 9x system. Before the tool wasn't able to open files unders Windows 95, 9x and Me. This major bug was fixed together with other bugs. Also a header parsing code was greatly improved.
The latest version is as usually available in the download section. The archive contains a WhatsNew.txt file which describes in details all the fixes contained in version 1.0.2.

[5/30/2005]

Some minor bugs dicovered in AsfBin

Right after releasing I found some bugs in the AsfBin code.
Now they are already corrected and the new version 1.0.1 is available in the AsfBin download section.

Problems with accessing RadioactivePages.com

Since 5th February I was moving the whole site to another site provider. Some unforeseen problems occured and the site was not accessible till today. Therefore I would like to apologize for all the inconveniece it could cause.

[8/14/2003]

Small corrections to AsfCut. Version 3.92 is ready.

During code review I have discovered some minor bugs in the latest version of AsfCut. Also tests performed on some Japanese OS showed that AsfCut may improperly convert text containing international characters. This relates to all input data that is command line parameters as well as all input text files.
Therefore in this version AsfCut converts all strings using currenty selected system locale (set in Reginal Settings).
A bug causing the audio streams not to be played in some rare cases was also removed.

[7/23/2003]

Lots of impovements in a new 3.9 version of ASFCut!

As I have discovered a lot of things hidding behind the ASF format a lot of things has been also changed in the new version of AsfCut. First of all, processing files should be more accurate. Frame losing should now never happen.
From now on there will be two versions of AsfCut executable:
-  supporting new Windows Media Services 9 (only with this version it is possible to copy codecs description properly; lack of this information however doesn't have any impact on file playback),
-  working with all versions of Windows Media Services.

Aside from that the version 3.9 features:

• a new -pre switch, which forces AsfCut to start copying right before specified start time. This ensures that no matter how key frames are distributed across the input files, given fragment will be entirely included in the output file (*),
• stream mutual exclusion object is properly copied,
• removed -noaudioresync switch as this feature is no longer necessary,
• added -bw <milliseconds> switch to set desired buffer window time. It is usefull if you get a message that a leacky bucket was overflowed. In such cases you won't lose samples but playback may be non-linear in some places.
• corrected bug causing markers from the second or further files not being copied at all,
• improved shifting audio streams when a time offset is negative.

* - see Readme.txt for more details

Proceed to download section.

[4/18/2003]

Version 3.5 of ASFCut is out!

At last a new version 3.5 of AsfCut has been made available online! I have good news to those who could be disappointed with quality of processing provided version 3.0. Especially when it came to processing WMV files.
The nastiest bug has been removed!
I was hoping to receive some help from Microsoft SDK team, as it was caused by a bug in the Windows Media Format SDK, but finally I had to do it myself.

Here is what's new in the version 3.5 apart from solving that bug:

• The chronological order of segments is completely unlimited. Thus, any repetitions, overlapping and other effect are possible to achieve by use of this tool.
• Improved editing of audio files. When copying audio files (*.WMA) all samples times are modified to avoid accidental losing of samples. To prevent changing time of audio samples use -noaudioresync switch.
• Improved handling of damaged files. Method of restart after stream error was improved as well.
• Corrected extraction of short segments (shorter than about 10 seconds depending on file).
• Removed bug causing some extracted segments to lose audio. However the reason is unknown and it is still possible to lost audio in some rare cases. See Known bugs section for more details.

Proceed to download section.

[2/26/2003]

Donation can be made online

For all of you, who would like to encourage further development of the software shared to you on my web site (that is: SubCreator, AsfCut and BinVote) I have prepared a special page, where you would be able to make an online donation in any amount through the Kagi payment service.
Any donations are highly appreciated :) Jump to Donations page.

[2/11/2003]

Site moved to an independent domain!

At last I have moved my whole site to a new domain. From now on I am using a different service provider. I hope that this will give me more possibilities to extent my site functionality as well as software itself.
I hope that the move won't cause to many problems to you.

[1/16/2003]

BinVote premiere

I am proud to present you a brand new application - BinVote, which main goal is correction of audio files. In particular, removing jitter correction errors and other glitches that could appear after grabbing damaged or scratched audio CD. When even that application like EAC wouldn't be able to grab an audio track with no errors, then in such case you can use BinVote in order to make a direct correction of just read audio signal (WAV file). Only damaged areas are corrected so the modified amount of data is minimal and usual it is about 0.01%.
Please go to the new section describing the details of BinVote.
Using BinVote not only you can restore audio files, but you can also correct any kind of files. Basing on multiple copies of that file you can likely restore the original content although all those copies are damaged. The method of reconstruction is based on simply method - voting. From that comes the name BinVote - Binary Voting.

[1/10/2003]

With New Year a new web site layout.

Maybe not quite new site graphics, but the layout has been totally changed. It is prepared to adopt a new application. There are also some changes in the SubCretor section. A new topic, "SubCreator Language Versions" has been added.
Section "About" was expanded and a new page devoted to my second big hobby, electronics, has been added. There you can read about a Hi-Fi amplifier I have made myself.

[11/4/2002]

There a solution for the most painful ASFCut 3.0 bug!

For a long time there was quite serious bug in ASFCut. Key frames of size bigger then certain value were being lost during copying of WMV files. Thus ASFCut for some people could be totally unusable :(
However, finally I have got some help from Microsoft staff in this matter, so now I able to solve it. New version is already tested but the workaround is a heuristic algorithm and it needs some tests to be performed. Soon expect release of a new version - ASFCut 3.1 is coming!!!

[10/2/2002]

ASFCut 3.0 is out!

At last! After a lot of hours spent on testing and correcting I am ready with the release of the next version of ASFCut. This time it is next full number 3.0 as it has totally rewritten engine in order to add some new features.

What's new in version 3.0:

• possibility to shift audio streams in respect to video and script streams,
• possibility to set attributes like Title, Author, Description...
• more options when it comes to repairing of damaged ASF files,
• improved accuracy of cutting and marker copying,
• all samples are ALWAYS sorted chronologically, so even if in a source there are some errors they will be corrected.
• removing gaps feature was added allowing to repair certain types of irregularities.

Of course as before, all features can be applied simultaneously so cutting, joining, repairing and shifting audio stream can be done in one single pass. Command line parser is as flexible as it can be, so use of ASFCut tool shouldn't be a problem even for users with minimum experience in using command line tools. To download the newer version please, go to this page.

[8/9/2002]

SubCreator 1.2 - some corrections needed :-(

Unfortunately even in this version some bugs were found. One of them is especially dangerous. When closing, SubCreator asks to save unsaved document. If you choose "Cancel" SubCreator will close anyway discarding all changes has been made!!! So for now please be careful. Very soon a corrected release should appear.

[8/9/2002]

Localization of SubCreator help on the way.

Apparently there are some nice, hard-working people in the world who want to devote their precious time to make a translation of SubCreator help file to their native languages. Here they are:

• Frans van Beers - Dutch,
• Ivan Krasimiroff - Bulgarian.

All volunteers are sincerely welcomed. It would be very nice to have also other translations as well. Especially German, French, Spanish, Italian, Chinese, Japanese... All what is required is good knowledge of English, persistence in work and some amount of spare time :-)

[8/6/2002]

100.000 Hits !!!!!

Of course I have missed the moment. Now a counter shows above 102000 hits!
Cool, this is really cool, hehe hehe hehe ;-)))
But where is champagne?

[7/12/2002]

New version of SubCreator released - 1.2

Unfortunately there where some bugs, especially in part responsible for editing and creating new subtitles. Of course there is also some new features:

• Text encoding setting from menu Edit | Encoding. Encoding is stored separately for each language installed in the system.
  
• Behavior of Ctrl-W and Ctrl-Q shortcuts (Add/Increase timestamp) can be switched to work as in version 1.0.
  
• New Processing function: automatic line duration adjustment basing on text length and number of words. Parameters in the formula can be estimated on any other existing and well timed subtitle. Just open that subtitle and in the Action configuration press "Get Stats" button.
  
• Ctrl-Shift-A shortcut sets stop time for a give line.
  
• All code was reviewed to increase stability and to make easier finding any strange behavior.
  

Go to the Download section for the new version.

[4/8/2002]

Download statistics

Analyzing statistics I can say that so far there are at least 2500 users of a new version of SubCreator and what is more surprising me is that about 20% of user are from Japan. So far only one bug report. Maybe I am wrong and there aren't that many users of SubCreator. So, if you have detected any bug or if you have some cool ideas on how to improve the application, please, don't hesitate, just mail me. Can be also in Japanese:)) I started to learn this language half a year before!

Language support issue

Unfortunately not all languages are supported by SubCreator 1.1. I totally forgot about right-to-left reading languages like Hebrew or Arabic. Those languages weren't tested at all and some people are reporting bugs concerning improper handling of question marks.

[2/19/2002]

SubCreator version 1.1 is out!!!

Finally next version of SubCreator is ready!
In this version I've placed emphasis on bugs correction, improving edition and stability. You will find also a lot of new functionality. Below is a list of more important improvements.

New features in version 1.1:

• This version should hopefully support all characters specific to "non-English" languages under Microsoft Windows 2000 and Windows XP. Because those operating systems do not support applications using Rich Edit 1.0, a separate DLL file has to be placed in the SubCreator working directory. SubCreator has been tested on Win98 PL, WinNT 4.0 Eng, Win2000 PL, Win 98 Japanese, Win XP Eng and Win XP NL.
  
  
• Support for Far East languages has been added. Of course not all features are available for those languages. (E.g. automatic line dividing). Although this feature isn't visually impressive it required lots of changes in almost all source codes. It has been tested under Win 98 Japanese.
  
  
• Multilevel undo feature has been added. Use Ctrl-Z for undoing an action and Ctrl-Shift-Z to redo an action.
  
  
• A "Smart adding of timestamp" feature has been added which automatically scrolls the content of the script file to the proper place and moves the caret to the next beginning of a subtitle line.
  
  
• You can define the amount of time by which the timestamp will be decreased when adding a timestamp during movie playback. This is a correction time for you reflex
  
  
• Added the possibility to change the default duration of selected lines. You don't have to toil over placing proper repetition lines or empty lines which shortens duration time anymore. Just use Ctrl-Q to increase or CTRL-E to decrease duration times. The "auxiliary lines" will be added automatically when necessary.
  
  
• You can specify the "advance time" if you want to synchronize the movie time to the time of the current subtitle line.
  
  
• Each Open dialog can now open both a script file and a movie file simultaneously. Also a new drag and drop feature can accept both files. SubCreator should properly distinguish text files from movie files.
  
  
• Removed bugs related with the new line character. SubCreator should properly handle text files written in DOS/UNIX/MAC/Amiga format. All files are written in DOS format.
  
  
• Corrected bug that occurred when exporting a script file to SRT format.
  
  
• Added a popup menu to all text editors in the SubCreator. It is also possible to search for any text in the Processing dialog and in the Export dialog.
  
  
• Added "Interactive Line dividing" feature to the Processing dialog. This function supports dividing an over lengthy subtitle line into two shorter ones. Start times and duration times are set automatically. Now you don't have to worry about a subtitle that take 3, 4 or more lines on a screen. Of course this function does not guarantee voice synchronization (yet:)
  
  
• Added Tip of the Day dialog. There are a lot of people who do not use help system for unknown reasons;)

[11/9/2001]

SubCreator version 1.1 is out!!!

People are reporting bugs in SubCreator, so some more important are placed on a Bugs Reporting page.
So far I am working on a more intelligent adding timestamps and multilevel undo.

[10/18/2001]

SubCreator version 1.0 is ready!

SubCreator version 1.0 beta is ready at last!
A freeware tool supporting the process of subtitles creation. It is a combination of a movie player and a subtitle editor in one with many special feature added. More on this tool you can find on the Download page.

Whew! It was a lot of work. SubCreator was scheduled by me on the middle august, but writing help was very time-consuming process. Also polishing the program and adding some new features took me another couple of weeks. Near the end I have added SAMI format support...
Never less - it's ready now. You can download and use it for free. Then you can tell me what do you think about this tool. What can be improved and what can be changed.
So far below is a list of what I wish to add in the next version:

• style support (but without complicating the timing process) - this would be tough and will be connected with even stronger SSA format support,
• better parsing of SAMI scripts,
• improving GUI,
• improving displaying of subtitles
