mp3

[motor30]

just wondering if we purchase the mp3 device for pa800, what we might expect? for example, can we separate the singer voice and play with it? etc...thanks

Hi Motor30,

An MP3 recording is a single stereo track only. So the answer to your question is no.

If you want to capture several digital recording tracks and play around with EFX and gain and fade in/out later on, then you can do this using many PC based DAW multitrack recorders, or you could use something like the Zoom HD16 HD recorder.

Best regards,
Rob

Hi Rob,

I think what Motor30 is trying to accoomplish is the karaoke utility to probably nulify the vocals. To what I know, I think this is not possible with the mp3 board.

Your thoughts on this will be very valuable Rob.

Most people doing Karaoke will purchase MIDI files with lyrics and score, not MP3 files. MP3 files are complete single track stereo recordings and vocal tracks can not be separately muted.

There is a Karaoke DVD format available with Video-based lyrics and two separate sound tracks, one of which has lyrics, and the other which does not. This may be something you want to look into, if you need sample vocal tracks.

Best regards,

That's right. Most karaoke producers don't do the midi versions anymore though. They sell stereo audio tracks;however, you can purchase a second set that does not contain vocals at all. So you would have to ask for the instrumental version.

What about those softwares that remove vocals from tracks? would those help?

Nah! those softwares are more like the other ones that claim to convert multi track stereo files to midi. I know how they work. It's impossible to do it without degrading the quality. Vocals share lots of midrange frequencies with just about any instrument in the track. Some people use them from time to time. Let's say you play Bass, and you can't hear the Bass line very well in your favorite track, so you use those to cut higher frequncies to hear the Bass better...but that can be done with any EQ filter. Another thing they do, they split the stereo to 2 seperate mono tracks, and reverse one..so the sounds that are placed in the center tend to disappear in the mix, but nothing useful for a professional stage gig..

I'd like to add my two cents on this topic , if I may . I heve tried several of those "voice zapper" softawres . It is based on a technical phase cancellation of the tracks comprising the main vocal . Unfortunately, it does not "always" work , and sometimes you end up with the reverb tail on the back . So in my humble opinion , most of these tracks are good enough for a serious performer. On the other hand it serves a purpose of practicing on top of the mp3 file . I enjoy using the karaoke mp3 as a background for playing usually piano parts and ocassionally singing . ( I pitch shift the whole arrangement to suit my poor vocals ) but the point for me is to have fun. I am eagerly expecting a technology called DNC. I think that there could be a chance to remove the vocals in some tracks with that , without sacrifice of the original quality . We'll have to wait 'till it gets released and see.
(Sorry for the extensive post)

I agree with Sam. Due to the nature of the recording, you're going to get extremely random results with these softwares. You might get a ok one from from time to time, but dont' expect that with most of the recordings, especially if there's more than a solo vocalist panned all over the place.

The new technology I was referring to is called DNA (for Direct Note Access)

Hi, do you have any web reference for it that you can share, please?

Thanks,

Yes Rob...check this one out if you will http://es.youtube.com/watch?v=UE-wrYK8JSY

Thank you so much for letting me know about the new Melodyne technology. It's extremely clever and innovative, and will be very valuable for recording studios I am sure. I can see that the technology could perhaps be used in a Karaoke player to separate out vocals from accompaniment. Have you asked them about a Karaoke application of their technology?

Best regards,

I have about 2500 Mp3 files with no vocals. They are full songs, not midi, with no vocals, some of them have back vocals.

I wonder how do they do that than if you can't remove vocals.
