Playing with audio

-
I recorded an audio of 34 hours as a test. Wanted to go through that hour by hour and figure out a good way to do that. ChatGPT suggested Audacity. I ended up with version 3.7.7. The installer worked fine on windows.

But the instructions chatGPT provided, did not work exactly but I was able to find the menus and split the file into hour chunks by using labels. It although detected only 14 hours of audio. The split chunks played fine, so seemed like some kind of issue with either data or the audio-file. In the recording software I checked the size and playback and it was fine and the file size reported of ~10GB was also fine. Then further R&D on chatGPT told me it could be erroneous header. It provided a command using ffmpeg to fix that so that Audocity sees full 34 hours of file. Below is the command

ffmpeg -err_detect ignore_err -i input.wav -c copy fixed.wav

But first I had to install ffmped. That involved downloading a latest build, then creating c:/ffmpeg. And then edit path so that we can run the command. Thankfully it worked fine.

After this I have to again split the file if Audacity sees it properly. Splitting has a good side - the 10GB original file loads very slow. But the split files are easy to handle and load quite fast. The labels have numbering and provide enough context to figure out timestamps from start.
Lets see how it does.

QCalendarWidget CSS Stylesheeting

-
Recently I had to implement a calendar for a TouchScreen application. I resorted to css to modify the calendar widget's appearance so that it would be more accessible. Following is the code that enabled me to get a proper calendar. calendar->setStyleSheet("QMenu { font-size:20px; width: 300px; left: 20px; }"     "QToolButton {icon-size: 48px, 48px; font: 20px; height: 70px; width: 100px; }"     "QAbstractItemView {selection-background-color: rgb(255, 174, 0);}"     "QToolButton::menu-indicator{ width: 50px;}"     "QToolButton::menu-indicator:pressed,"     "QToolButton::menu-indicator:open{ top:10px; left: 10px;}"     "QTableView { font: 30px; }"     "QSpinBox { width: 100px; font: 20px;}"     "QSpinBox::up-button { width:40px;}"     "QSpinBox::down-button { width:40px;}");

[Qt] Compiling ICU with MSVC (Microsoft Visual Studio)

-
Link to original article: http://qt-project.org/wiki/Compiling-ICU-with-MSVC Text highlighted and notes added Compiling ICU with MSVC (Microsoft Visual Studio)     Qt 5 / QtWebkit requires ICU.         Pre-built packages     The ICU Project site [ site.icu-project.org ] provides pre-built packages for MSVC 2010, which should work with compilers too. Anyhow, you have to compile your own version if you want to avoid the MSVC 2010 runtime dependency (because you’re using another MSVC version), or want to tailor the ICU configuration.     download.qt-project.org [ download.qt-project.org ] also hosts packages for MSVC 2012 .
