Just something i stumbled across probably old but i am curious to see what you picked

test

 

YEAH..I could work as an Audio Engineer..that my test result. Everything correct. I was even able to recognize a sine wave was 0,3db louder than another one!

Uhhh..but when I do this test

http://www.noiseaddicts.com/2009/03/can-you-hear-this-hearing-test/

I can only hear frequencies up to 14Khz...But maybe my headphones are simply bullshit!

 

MP3 in 320kb/s Constant Bit rate should be enough for the most people.
For the Audiophile you can forget MP3, best are FLAC, Wav or AiFF files (Lossless).

 

sound better than what?

 

You would hope it's your headphones I can only hear up to 18Khz and can just hear 19Khz if i turn the volume up, Bad for a 20 year old

?

 

I can't hear the difference between 160 and 320 for example...

 

I don't see a single reason for 320 kbit/s on MP3 because

1. you would need golden ears and a "golden" setup to hear a difference between 320 kbit/s and - let's say - 192 kbit/s (assuming a good encoder).
2. I believe there are no players left at all that don't support VBR, so no need for CBR at all. LAME will basically just use a padding for 320 kbit/s compared to -V 0, it's just a waste of storage space.
3. MP3 isn't lossless at any bitrate, so it's not really suitable for further processing or archiving, neither with 64 kbit/s nor with 320 kbit/s.

So what is 320 kbit/s exactly for?

I'm more than double as old!

 

I suggest "popping" your ears before taking the test (holding your nose and blowing gently until your ears pop) (especially with the volume test). or just me that needed it? due to a few too many years in front of club speakers.

I instantly could tell the volume differences when I did but on the 1st try only got the 1st question right. Oh and I got the mp3 q right but its not a great audio clip example in the 1st place.

Thes test below made me sad as I couldn't hear 15khz or above. (age and them damn club speakers)

Tone Test

 

Man, I heard FINE until 17kHz, then from 18 to 22 kHz i heard it like if was in really low volume

 

Go play your mp3's on a 10k to 100k system and tell me there is no difference. I use to dj for a major D&B label and every time I would come off the decks, people would come up to and say "dam man, why does the bass sound so good when you play".
"Thats because I use vinyl and all the other dj's use mp3's" I would say.

 

i hear not higher than 18.4 kHz (with microlab solo2mk3), not higher than 19.2 kHz with beyerdynamic dt 770 pro (headphones) with high volume. tested with sine signal. 22 years old. My little brother hears up to 22 kHz (i switched sine with 22kHz and he didn't know that, and he said that smth whistles very loud) - 13 years old. My girlfriend (22years old) still hears freqs up to 20 kHz, i don't. My grandpa only up to VERY LOUD 14k (approximately), 64 y.o.

 

Just listen Hi-Hat with quality headphone... you will hear the difference immediately

 

Some info on the human ears: The books will tell you the normal range of human hearing is 20hz to 20KHz. While this may be true in a few humans, it is more often in the 25Hz to 18,000 KHz range, and this is assuming clean, unobstructed ears, and no damage to the ear drums. Also, as one ages, their ability to hear the very highest frequencies diminishes ... it may be likely that someone in their 60's, for example, can only hear in the 14khz to 15khz range. It depends on what their ears have been exposed to during the course of their lives. For example ... many people that are ex-military and want to be audio engineers that worked on the flight line, or fired big guns or cannons, most all have some hearing loss, and some so bad they can simply no due audio as their range of hearing is severely diminished.

If you want to know how the human ear hears, reference Fletcher Munson, and the Fletcher Munson Curve. Know this ... listening to sound over 90 db will damage your ears over time. Additionally, you will also learn that when you listen to music very loud you hear it wrong! And yea .. when you mix loud, you mix wrong. Professionals know this. You should be mixing in the 80 to 85 Db range ... or what we call normal room volume.

There is a series of ear training disks that people may be interested in ...The are the Golden Ears series ... 8 CD's and a book. Training with these will help one to hear through a recording and hear things non-professionals would not notice.

The algorithms that are used to compress images (jpeg) AND audio (mpeg) are designed to eliminate data that the average human hear would not hear, or perceive. PERCEIVE is an important word here, because a "trained" ear will hear and perceive far more than the non-trained ear. This includes the ability to hear and perceive the tonal color of different hardware. There is a big difference between the resolution of a 300+ kbs file and something in the 100kbs range .. the question is .... can you hear it. A trained ear can. The novice, not so much. But then, that is the intention. Reference consumer electronics ... what a "consumer" uses and what a professional uses are two very different things.

OK, hope this little tid bit of info is useful to some one.

 

mp3 @320 kb/s, for me it's the starting point not an optional

 

"Go play your mp3's on a 10k to 100k system and tell me there is no difference."
DAT!
on headphone or a multimedia setup, no problem.

" So what is 320 kbit/s exactly for? "
To listen listen to music in good condition with a limited storage.
Because your ears or equipment are in bad shape, doesn't mean it's pointless to everyone.

 

I could hear all of the samples surprisingly, right up to 22kHz

 

Age?

 

I can tell the difference between 320kbps MP3 and lossless, however I don't think I can really tell between 320kbps MP4 and lossless.
