OT: An observation and question about frequencies.

[mpetersen3]

Yay my guess was right! uhh kinda.

[Monika.mhz]

So why is it that almost every electronic song has the 20khz turn to something like -30 db? Just weird.

because it's an mp3.

[Foreverhex]

because it's an mp3.

I think that might just be my answer.

Edit: Just looked into my track in mp3 format instead of wav.... Monika was right. She seems to be good at that. lol

Leaving the higher freq in tracks can set off certain emotions without you knowing, im studying psycho acoustics at university and we cover this alot, same with low freq u cant hear, but they are ther doing ther bit.

Holy Jesus, that sounds goddamn interesting. Of course you get effected by
the sound, it may be too much or too less for your ears., but your body still receives the audio waves.

Edit: Oh shit, thought it was English. Its about torture with low frequenct about 5-25Hz, that makes you puke. Or Audiowave Guns.
They also built huge mobile soundsystems to play a low frequency at a riot.

And really low frequencies can cause inner bleedings which can kill you.

Crazy shit.

ah, the infamous "brown sound"

I think that is a south park reference?

The range of human hearing stretches from 20hz-20Khz and generally tails off as you get older. Most people can't hear above 15-18Khz.

It's thought that we can perceieve frequencies higher than 20Khz, but can't hear them - although it's never been conclusively proven and IMHO is something people say to sell the latest technology - 96Khz workstations for example.

Having any frequencies above 20K or below 20hz will only rob any mixes of energy, particularly when mastering, so it's wise to put cuts in to remove those frequencies to maintain the optimum level. In practise most dance music will cut at about 18khz.

The more high frequency content there is in your audio, the more fatiguing to listen to it is.

The Sony Philips Sampling Rate Issue is Beethoven to blame for 44.1khz?

Damn straight!

I'd rather listen to a track with freqs over 18khz than one that's been overly compressed.

Compressed audio is FAR more fatiguing to listen to than music with high end.
