The main help page

 


This is the help page for the Recorder tool, which is part of the KarVCD toolset. The purpose of this tool is to record the sound present at the input of your sound card to a WAVE file. It can also play a MIDI, KAR or WAVE file while recording. If the lyrics embedded in a KAR file are available, they will be shown as well.

Operation

 


The Recorder Dialog

Let us take a look at the MIDI converter window fields and buttons:

At the top of the Recorder dialog there is the Playback group of controls with the following elements:

®       File type. These two radio buttons let you choose the file to play either the WAVE file or the MIDI/KAR file selected in the main window. You can also opt for not using playback at all.

®       File name. This field shows the file to play.

®       Browse. This button lets you load another file to play.

Bellow the Playback group there is the Show lyrics group with three radio buttons. These let you choose the type of lyrics window to show while the playback file is being played.

Bellow the Show lyrics group there is the Output file group of controls with the following elements:

®       File name. This field shows the file that will be created during the recording process.

®       Browse. This button lets you select another file to record.

Follows a description of the remaining elements:

®       Progress bar. This control shows the progress as the playback file is being played. This will only be shown when there is a playback file.

®       Start. This button initiates the recording process.

®       Stop. This button stops the playing process.

®       Play. This button lets you hear the output file that was created during the recording process.

®       Status. This field shows you the time already played versus the total playing time when there is a file being played; otherwise it will show the time already recorded.

®       Help. This button shows you the file that you are now reading.

®       Close. This button closes the Recorder Dialog and returns you to the Main Window.

 


The Lyrics Window

When KarVCD is playing a file and it has access to the lyrics corresponding to that file, it will show you the lyrics in a window. You can choose between a normal window and full screen. The normal window looks like this:

The full window has the same elements in the client area but doesnít have a title bar or borders.

The lyrics window has four lines of text. The text is initially shown in white characters. As the music corresponding to a word or syllable is played, that word or syllable is shown in red. When all the words in a line are red, playing starts at the next line.

Playing starts at the third line of text. As that line of text is completed, playing resumes at the fourth line. At the end of that line, playing continues at the first line, after which it continues on the second line, and so on.

At the transition from line 3 to 4, if the first and second lines have already been played, they will be updated with the new words that follow the fourth line. Similarly, during the transition from line 1 to line 2, the third and fourth lines will be updated with new text.

Whenever there is a part of a song that is purely instrumental, the window will show a delay bar instead of the first and second lines of text. The third and forth lines will show the text that follows the instrumental. The delay bar shows in a continuous way how much time there is before the end of the instrumental: Initially the delay bar is all white; as the instrumental progresses, part of the delay bar will be painted red; when all of the delay bar is red, the instrumental is ending.

The lyrics window, when not in full-screen mode, is resizable to any dimensions that you want. As you resize the window, the text will be resized accordingly. If a line of text doesnít fit in the window, the text will scroll horizontally, as each word is being played.

 


Operation

The operation of the Player is very simple: You select the playback and output files, choose the type of lyrics window you want and hit Start.

When there is a playback file, the recorder assumes that the file to record has the same length. Therefore it will stop recording when the playback file reaches the end. When there is no playback file, you have to stop the recorder manually.

The recorder will record any sound that is present at the input of your sound card. It is up to you to configure the Windows sound mixer (thatís the small loudspeaker icon on your system tray) to control what sounds reach the input. This varies from system to system but usually you can select the microphone input and the line in input.

Some sound cards let you record the sound that they produce when playing a MIDI/KAR file. This feature can be used as an alternative to the KarVCD MIDI converter, as another way of converting MIDI/KAR files to WAVE, using your sound card synthesizer. In this way you can also use any other Windows defined synthesizer, internal or external, soft- or hardware based.

The ability to playback a WAVE file while recording another depends on your sound card hardware. This is referred to as ďfull-duplexĒ in the list of features. The majority of modern sound cards have this capability.

The Recorder will work with the files that were selected in the main window. You can also load new files in the Recorder tool. In that case, the main window will reflect that fact.

The Recorder will use the hardware devices selected in the Options Dialog. To play WAVE files it will use the Wave output device, to play MIDI/KAR files will use the MIDI output device and finally for recording it will use the Wave input device. This allows you to use any Windows defined device, internal or external.

Whenever you playback a KAR file with embedded lyrics, the Recorder can show you the lyrics in the Lyrics window. You can choose between a normal window and full screen. You can also disable the Lyrics window altogether.

When you playback a WAVE file and there is a KAR file loaded as well, the Recorder assumes that the WAVE file corresponds to the rendering of the KAR file and shows you the lyrics just like when you play the KAR file.

When the lyrics window is showing, normal or full-screen, hitting any keyboard key will cause the window to be closed and the playing/recording to stop.

When you close the Recorder Dialog with the Close button, the program will set the output file as the WAVE file in the main window. Before doing this, the program makes sure that the output file does in fact exist.
