I export my MP3 in mono..is that wrong?

[feaker]

Going to really have to check this out. By the time one of my songs gets to taxi, and I play it on the forum, it has lost a lot. Especially the bass. It should sound the same as playing it off the jump drive I am using?Anyhow, I have to get to the bottom of this.Thanks again you's guys:)Paul

The Taxi "chipmunk" process probably degrades your song a bit...I think it does for mine. The fine print states that the screeners listen to your mp3 as you uploaded it...the Taxi green "play" button launches a compressed version of your song. So we hear a fuzzier version than the screener does (I hope).I don't know if compression normally messes with the top end (higher frequencies) more than the bottom end...it seems to from what I hear before/after the Taxi chipmunk treatment.

Devin, Mojo, Dave, Suz and All Thank you, thank you, thank you for all this good info. Nothin' like some help from my friends for get up another notch in the seemingly Sysiphean never-ending learning curve! And Paul .. thank you for asking the question!

Suz - You're spot on with your data compression information summary. (Is that a dedundant statement???)

Is 320 kbps audibly better than 160 kpbs? It depends. But the principle remains that you can always downgrade from 320 kbps to 128, if needed. Yet if you start with 128 kbps, that's as good as it gets.Pardon my yammering. Hope it helps.Brad

Turns out that all I needed was an updated DLL file for the LAME encoder used by my old (and familiar) Steinberg WAVE program. And it worked just fine. However, I now have a copy of Audacity too (how cool that it's free) and will get acquanted with it eventually.

mojobone, why don't you convert your mp3 files from Tracktion?

This is a very helpful thread -- thanks for starting it all off with your questions, Paul. And grazi for the reminders about sampling rates, Brad. I haven't researched loss-less compression yet. Any compatibility issues when exporting songs in loss-less compressed formats versus lossy?Also, I've been uploading my songs to Taxi at 320 kbps; guess I thought that the 192 kbps was a minimum quality suggestion. Am i wrong? Are the compression police going to get me? !!Thanks, fellow data-crunchers and audiophiles! This is fascinating!Think I'm going to go calculate pi to a thousand places now . . . Suz

I'd get players on the other team saying "what's with the three digit number?!?"For a while, I was home-run champ, so I'd just tell them they would understand later after I made another full circle.Only one person ever got that joke...

Quote from TAXI member data:Make sure that your song files are MP3s, are 10 MB or less, and have a bit rate of 192 kbps or less.More info can be found here:http://www.taximusic.com/faqs.php#convert-mp3 Chuck

FWIW, I get better sound going to mp3 straight from 24 bit file. I use Cool Edit. I can hear a difference between 128 and 192kps, not so much between 192 and 320.jazzstan, I just use a flash drive and work on two computers. That way I keep the music puter offline. It's not too much of a PITA...
