Sliding on Video or Photo to Control Volume and Fast Forward / Rewind

   Inside Bluekara, you can always use the following way to control Music volume.

   When the KTV Video is playing, you can slide on the video from bottom to top to increase music volume, and slide from top to bottom to decrease music volume.

   When you play music MP3 with photo slideshow, you can slide on the right side of photos  from bottom to top to increase music volume, and slide from top to bottom to decrease music volume. You can also slide on the left side of photos  from bottom to top to fast forward the MP3 music, and slide from top to bottom to fast rewind the MP3 music.

The Lyric file format (.lrc or .cdg ) for singing MP3 songs inside Bluekara

   When you sing or listen to Mp3/WMA songs, you need lrc file with the same MP3 file name (for example, A.mp3 , you need A.lrc or .cdg file) to show the dynamic lyrics for the MP3 songs.

   Bluekara can sing /record/ Pitch-shift/music Equalize the MP3 file, and slideshow your photo as MP3 music playback background pictures at the same time. (For photo slideshow, you must put your own photos into bluekara/ Photos folder).

   Since MP3 file is not designed to sing Karaoke, so when you want to remove the vocal, you should enable vocal remove, but disable vocal in right channel option. The vocal remove effect, will depend on the MP3 songs. In general, if the MP3 song record the lead vocal in center of both audio  stereo channels, and without any echo or reverb effect, the vocal remove effect can be more perfect. As for other effects like record, pitch-shift, EQ and slideshow photos,  can be suitable for every MP3/WMA songs inside Bluekara.

    To dynamically display lyrics, Bluekara support the LRC format as follows:
(The general Lrc format).

[ti: I can tell you why]
[ar: Eagles]
[offset::0]
[00:23]Look at us baby, up all night
[00:28]Tearing our love apart
[00:34]Aren't we the same two people who lived

If the lyrics displayed as messy coding,you can change the LRC encode method from music control console inside Bluekara, to show the correct lyrics.

The Lrc file above only shows the lyrics for whole sentence, so when Bluekara want to show the lyrics by words, the words lyrics can only be constantly and even-time distributed to the whole sentence. Hence it is impossible to do the exactly word lyrics displaying. (So, the above lrc format is only suitable for whole sentence lyrics displaying)

If you want to have exactly word lyrics displaying instead of only exactly sentence lyric displaying, Bluekara support the following dynamic Lrc file format. (.trc format)
 

[ar:demi lovato]
[ti:Let It Go]
[al:]
[offset:0]
[00:00.69]<200>Let <204>it <1050>go
[00:02.14]<250>Let <150>it <1450>go
[00:03.99]<200>Can't <700>hold <201>you <250>back <1951>anymore
[00:07.30]<200>Let <300>it <1100>go
[00:08.90]<250>Let <450>it <1200>go
[00:10.80]<250>Turn <201>my <200>back <350>and <350>slam <450>the <3751>door

   Since  the word display time has been embedded into every sentences , so when Bluelara show the lyrics gradually, it will read the word display time information to make words lyrics more precisely to display.

Bluekara can also support another trc format like the following formats.

[offset:2851]
[000:6.540][400,700,1100]There's a fire
[000:8.741][600,250,600,400]starting in my heart
[000:10.993][850,300,501,450]Reaching a fever pitch
[000:13.093][200,151,449]and it's bringing
[000:13.894][200,200,200,1000]me out the dark

The above format can also make words lyrics more precisely to display.

  If you have cdg file associate with mp3 file, Bluekara also can support to sing and overlay lyrics graphics with your own photos. All the pitch shift / vocal remove / recording effect still can work for this type of Mp3 file.
