Hey guys is there any mp3s online that you guys use to tune your equipment?

All my mp3's are of different quality and it's hard to pick out different highs and lows

I was hoping to doing via iPod or burn to cd if that would give any better quality

Thanks guys

Use a real CD to tune, not MP3s.
Chesky Ultimate Demonstration Disc, Sheffield Labs 'My Disc', MEASQ 2012 Judging Disc...these are all good for tuning to.

If you can find an "Alpine First Encounter" first disc anyway thats an excellent disc used in the 2010 MEASQ Season IIRC. However heres some discussion about the 2012 disc http://www.mobileele...02012%20%20disc I prefer it so much more to 2011's Cheesky disc, the disc isn't commercially available as only judges for the MEASQ season have them how ever the if you happen to have access to some of the CD's that contain this song thats a good way to get some judging material.

If you own an iPhone or iTouch you can use Apps to tune with like free tone generators. I have one called Sound Check that plays sine waves from 20Hz thru to 20kHz in 1/3 octave steps that's handy for things like phase checks, testing for panel resonance and stuff like that.

That would also work for G-EQ right?

Pure tone may not to too helpful when it comes to setting EQ, moreso just doing basic set up checks beforehand.

It is primarily great for phase checks left/right and front/back, plus I find it very handy when searching for buzzing panels for deadening purposes.

Thanks for the info guys just trying to find some of those cd's is it worth getting the songs in.flac? Or cd still better?

Thanks

[~Spyne~]

cd is still better, though flac can be exceptionally close (inaudible difference)
referencediscs.com.au has quite a few titles that would be suitable.

hey guys i bought Sheffield Lab - My Disc and Chesky Records - World's Greatest Audiophile Vocal Recordings

now, dumb question, whats the best way to tune the system?

[~Spyne~]

Depends what your goal is.
Don't take this the wrong way, but it sounds like you have no idea, so I would highly recommend visiting a reputable store, such as FHRX Studios and asking Marty to sit down with you and show you how to go about tuning.
First off there's basic level setting and phase, then crossover points and slopes. Time alignment (if your headunit has that feature), further crossover tuning and then EQ. It's near impossible to walk you through it online, without hearing your car, hence my recommendation to visit Marty.

Have a read of this, this will give you basic idea but as Spyne has suggested perhaps take it to a reputable shop if you are too unsure.
