How to figure out a song...

[Hell-Razor 0]

I have been searching around now for a good 30 minutes on how to figure out the bass in a song. I know you use some program and play the song through it. You then select a little bit of the audio stream and analyze it somehow and it will show how low the bass gets...

(I am trying to figure out the bass line in

song. When it drops to the second lowest, I have never heard my car rattle so much nor my woofer get so loud. The first bass "hit" is at 34.5 seconds. And the bass hit at 37.5 seconds I need to filter out. I see the speaker move for it but cant hear anything)

programs such as audacity or wavepad sound editor will work nicely

ah HA! thank you! with that help i found Bass Hz analyzer program?? - SSA Car Audio Forum

it says that the song peaks at 31hz... which is where my box is tuned at. But to my ear when I play "

" on that same album, which also hits 31hz, it doesnt seem to hit nearly as hard. I wonder why that is... Edited June 9, 2010 by Hell-Razor

I could be wrong, but I'm pretty sure thats information your going to need.

I hope your subs/amps are under warranty. best of luck.

reason:

My enclosure - 22 htz. / my peak frequency - 28 htz = my vehicles strongest note is 28 htz.

I'm not sure of the math. but test tones and termlab was used to figure this out.

What do you mean by "you hope my subs/amps are under warranty". You're the first person that I have ever heard talking about "cabin frequency". And how the sound plays in my cabin, how would that effect the wear and tear on my woofer? If I put something in my back seat, that would change the tuning (adding something). If I have a friend in the car, that would change the tuning. If I had my windows half / quarter up or down. that would change the frequency. As far as what I know cabin frequency only matters for when you do competitions to get that extra tenth of a db.

I don't remember the exact number but I think below 20hz your ear cannot hear, so why bother tuning THAT low? Its way way way too low. Most guys on here are from 30-38hz.

Sir, it was only a suggestion.

I'm a SQ competitor, not outlaw spl.

Hopefully someone else can jump in here and give you the info you need. Sorry for the disruption.

Maybe they recorded the bass at different levels on the different songs. Maybe it's at -3db on the one song, but -6db on the other.
