Lines), the player would respect the user settings, and will show lyrics using the defined blocks. Assuming the block length is in range of allowed by player (typically up to 8 If the player supports user-defined blocks (which only a few do, notably XBMC), then the lyrics creator can indicate the block boundaries by inserting an empty line on the block boundary. Then the lyrics are shown on a screen block by block, and the player highlighted the line or characters which are currently being sung. The player typically splits the lyrics text into smaller 4-8 line pieces of text,Ĭalled blocks. However this is not suitable for Karaoke purposes, because the player screen space is limited, so only some parts of text can be shown. The lyrics are typically represented as multiple lines of text. For example, to have lyrics shown 500ms earlier, replace the GAP value above by 32350 (32850 – 500). To make lyrics start earlier, decrease this value. In the case above the first lyric will show at 32.8 seconds. This line tells the player (in milliseconds) when the lyrics would start. To apply this delay to your lyrics, open it in the text editor, and find the line which starts with #GAP: #GAP: 32850 This would mean that your delay is -500ms. Compensating delay in UltraStar formatĪssuming you made lyrics in UltraStar format without setting up “Audio delay”, and when you play them on your Karaoke player, the text start 0.5 seconds later than the song. This line would instruct player to change all timing marks by substracting 500ms from hem. To apply this delay to your lyrics, open it in the text editor, and insert the line at the top: Compensating delay in LRC formatĪssuming you made lyrics in LRC format without setting up “Audio delay”, and when you play them on your Karaoke player, the text start 0.5 seconds later than the song. The value you should put there depends on your hardware and your Karaoke player, and you’ll find it experimentally. This delay is called “Audio delay introduced by Editor” and could be specified in the Advanced tab of Application settings. Because audio processing chain is different in the Editor and your Karaoke player, it takes different time for the moment the audio is being uncompressed to the moment the audio is heard in Since the music is typically compressed, it takes time to uncompress audio, convert it to the format suitable for sound output, and process it in sound card hardware. Solution: use constant bitrate MP3s for karaoke. While special VBR headers in MP3 files help the seeking, it is not very precise. If you ever used a seek slider during generating timings, it may not have proper value, and you would need to start your timing process again. Seeking in VBR files is also unrealiable. The “good” thing is that most Karaoke players also have issues with VBR MP3 files, so the right solution would be to recode such files to constant bit rate (CBR) as described here. While this typically does not affect regular music players, which do not rely on precise (up to 1/10 second) timings, this indeed affects Karaoke players. Even the special VBR headers are only used for more or less precise seeking, but not for proper time reporting. This may affect total time reported, and intermediate timings. While all of them support playing variable bitrate (VBR) MP3 files, almost no library seem to support proper playing time reporting. This is common issue to most media playing libraries. Invalid seeking/timing on variable MP3 files If there is no sound when you press the Play button on player, but the seek slider is showing progress, you need to make sure all your other audio players are closed (not just stopped). Please let me know if you still have this issue. Now it uses FFMpeg and SDL to play all media files. This happened a lot in past when Karaoke Lyrics Editor was based on Phonon. 5.3 Repacking variable bitrate (VBR) MP3 files to constant bitrate (CBR) MP3 filesĪudio issues Karaoke Lyric Editor does not play MP3 files on my Windows machine.2.2 Compensating delay in UltraStar format.1.3 Invalid seeking/timing on variable MP3 files.1.1 Karaoke Lyric Editor does not play MP3 files on my Windows machine.
