The Playlist and file options

The playlist is the main element of ZaraStudio. It shows the sequence of sound files and/or commands which are played or executed one by one. The elements that can appear in the list are:

Sound Files. Currently, ZaraStudio supports the following formats:

  • WAV.Loslessanduncompressedaudioformat.
  • MP2. Sound format that produces better quality than MP3 when using high bitrates (more than 256 kbps). This is the standard format in broadcasting, though is losing ground in favor of MP3.
  • MP3. Popular audio format for home use. ZaraStudio accepts any bit- rate (constant bit-rate or variable). When using constant bitrates, it is advised to use a minimum of 192 kbps, being recommendable to use 256 kbps to get a perfect broadcast audio quality.
  • OGG.Afreesoundfile,alternativetoMP3.
  • WMA.AWindowsMediasoundfile.ItisalsoanalternativetoMP3.
  • FLAC. Losless audio format, as WAV files. However, it does compress the audio, so it produces smaller files than WAV, though it does not compress as much as MP3.

Other Files

  • Playlists (.lst, .m3u and .pls files). This file is a command when it appears inside a list. Its purpose is to load a new list and close the previous one. The new list will begin to play, beginning with the first song. PLS lists remember the latest file played when opening them. These three formats are the same for ZaraStudio. The only slightly different one is PLS, as it remembers the last played song after opening the list. This feature is useful to change the musical programming at a certain time, by scheduling a file of one of these formats through an event.
  • Rotations (.rot files). A list of sound files in rotation. It contains a list of 9 tracks which play in the sequence as created. The tracks repeat in sequence. If a file in the list fails to play, the sequence will continue to the next file (failures noted in log file). The rotation file can contain any type of track (wav, mp3, commands, rotations…).
  • Sequences (.seq files). Sequences sound files. It contains a list of tracks that play all followed when playing the sequence. Like the rotations, the sequences can contain any type of tracks. They can be used to program advertising blocks.
  • Templates (.tpl files). Contain the definition of a music style based on random tracks. When a template is loaded, ZaraStudio adds audios to the playlist automatically as the player approaches to the end, following the guidelines specified by the template, so that there are always at least 15 audio minutes left to play.
  • Stop command (.stop files). Command that stops the playback.
  • Play command (.play files). Starts the playlist. It only makes sense as an immediate event.
  • Humidity files (.humidity). A sound file that says the humidity. In order to carry out this task, it is necessary to have the files with the proper name format in the Humidity directory, located in the folder where ZaraStudio is installed. The format of the files must be HUMXXX.mp3, where XXX is the corresponding humidity. For example, HUM100.mp3 is an audio clip that states: “the current humidity is 100%”.
  • Temperature files (.temperature). A sound file that says the temperature. In order to carry out this task, it is necessary to have the files with the proper name format in the Temperature directory, located in the folder where ZaraStudio is installed. The format of the files must be:
    • TMPXXX.mp3. This is a file that contains the audio clip for temperature XXX. For example, TMP025.mp3 is an audio clip that will say “25 degrees”.
    • TMPNXXX.mp3. This is a file that contains the audio clip for temperature XXX below zero. For example, TMPN003.mp3 is an audio clip that will say “3 degrees below zero”.
  • Time announcements (.time files). A sound file that says the time. Audio clips for hours and minutes must be properly located in the Time folder. The name of the files must be:
    1. MINXX.mp3. This is an audio clip of minute XX. For example, MIN01.mp3 will contain and audio that will say “one”.
    2. HRSXX.mp3. This is an audio clip of hour XX. For example, HRS18.mp3 will contain and audio that will say “it's eighteen hours”.
    3. HRSXX_O.MP3. This is an audio clip of hour XX o'clock. For example, 10
    4. HRS18_O.MP3 will contain and audio that will say “it's six o'clock”.
  • Pauses (.pause files). When playing, they cause a silence of a determined length. In order to create pauses it is necessary to execute the command playlist > Add pause…. Its duration must be specified between 0 and 3600 seconds.
  • Random tracks (.dir files). When played, a track is selected at random from the directory or sub-directory thereof specified. Random tracks have a system to avoid repetitions (see Options – Random tracks for more details). In order to create random tracks it is necessary to execute the command Playlist > Add random track…, which is in the pop up menu of the button from each player. If new files are added to the specified directory, they are automatically added to the random list.

This feature is useful to create random music programmings. A list in repeat mode can be created with several random tracks, that will define the random programming template. It is recommended to use this feature only in local folders in the computer which ZaraStudio is being executed, avoiding folders placed in other machines of the local network. Besides, it is not advisable to use this function with folders that contain a big amount of files, as this will slow down the audio pick up process.

  • Post-it (.txt, .htm and .html files). Command that opens a window, showing the contents of the text or HTML file.
  • Executables and scripts (.exe y .bat files). Command that runs the exe or bat file.
  • Load events command (.evt command). Loading another event file clears the current event list replacing it with events specified by the event file loaded.
  • On-line radios (.stream files). Plays the sound of an on-line radio station. Satellite connections (.satcon files). Enables the line in of the sound card specified in the options dialog.
  • Satellite disconnections (.satdis files). Mutes the line in of the sound card specified in the options dialog.
  • Enable the DTMF detector (.dtmfon files). Enables the DTMF tone detector.
  • Disabled the DTMF detector (.dtmfoff files). Disables the DTMF tone detector.
  • Enable LPT control (.lpton files). Enables remote control through the parallel port.
  • Disable LPT control (.lptoff files). Disables remote control through the parallel port.
  • Enable serial port control (.comon files). Enables remote control through serial port.
