Hi:

Lets say I have WMA file that is monoaural and 44.1 khz and contains a
song. What would be the minimum bit-rate neccesary in order for the
song to be recognizable to the ear of the average human who has
listened to the song before and knows the song?


Thanks,

Radium

Sorry that should be a 44.1 khz sample rate. I hate typos!

It would probably depend on the song. "Happy Birthday" performed on a
cheap keyboard with no accompanyment would be recognizable at a lower
bit rate than, say, Mahler's 8th Symphony.

Why do you want to do this anyway? It becomes unlistenable long before
it becomes unrecognizable.

This isn't really a question about bit-rate. It's about the minimum
information required to recognise a song.

Try
http://www.songtapper.com/s/tappingmain.bin?dotap=1

You might find one bit sufficient.

Interesting site. Did you know that you can tap in a song yourself and
add it to their database? Cool, huh? Sort of like Wikipedia, only for
sound.

Anyway, I tried tapping in "Happy Birthday" to see if it recognized it,
and got these results:

I Am A Transexual
Rod Conners

Happy Birthday
Unknown

I Wanna **** Aaron Carter
Lexi Henning

Aaron Slaney Is Homosexual
Chas N' Dave

Cool, huh?

I tried tapping in the following:

J. S. Bach, Tocatta and Fugue in d

J. S. Bach, Inventio #8 in F

Francois Couperin le Grande, La Favorite

Jan Pieterszoon Sweelink, Unter de Linden Grunde,
also Meine Junges Lieben hast ein Ende

and it didn't find a single one of them! So it REALLY
sucks! :-) :-) :-)

(but it will reconize them now :-)

And, the question for our radium: if I were to play you a
completely uncompressed rendition of, oh, Unter de
Linden grunde, would you recognize it?

Then act like a "scientist" and conduct some experiments
for yourself. Real scientists don't ask dozens of insane
questions on the interweb. They do their own work.
Windows Media Encoder (and several other resources)
were all suggested to you. They don't even cost anything.

Which, in the past, you have made a habit out of either
ignoring outright or confabulating into such blithering
nonsense as to render it essentially useless.

Where's the use in that? How "scientific" is that?

You have also made a career out of spatting ill-founded
personal opinions as "fact." Your ongoing declarations
about how FM synthesis is the best or worst or whatever
is notable not only for its frequency and poor factual basis,
but its complete uselessness. No one, absolutely no one
gives a ****.

Hello,

20kbps seems to be good.
WMA performs good compared to Mp3 at lower birates.. but, not below
23-20kbps.

I've never found a WMA file that has a 44.1 khz sample-rate but a
bit-rate below 20kbps. I'd like to find such, though.

Yes, there's a reason for that. Do the math.

If its a WMA file that monoaural and has a sample-rate that is at least
44.1 khz [and whose sample-rate is the same as the audio was when
uncompressed], then yes.

Then you have clearly wandered off into the field of
magic and have left technology behind. Perhaps you
should move your discussion to a newsgroup where
they discuss magic.

Do you truly not understand why this isn't possible,
or are you trolling us?

how discouraging this to people trying to provide the

How so? What is "magical" [or non-technological] about a monoaural WMA

sample-rate in its compressed and uncompressed form?

I really don't understand. Sorry if I seem like a troll but I am not.

I understand that, I missed to mention that details.
Encoding at 20Kbps can happen only with 22 or 32 KHz sampling. Thanks
for asking more info.

A 44.1khz sample rate in a 20kbps data stream?

Yes.

Adobe Audition 1.5 allows the production of a WMA file that is 44.1 khz
and 20kbps. How it does this is a mystery I'd love to learn about.

Where's the mystery? You can clock one bit of data at 44.1kHz (or any other
frequency for that matter) if you really want to.
Obviously some data must be repeated and/or invented, just as with all
compression schemes.

Would the songs be recognizable at 1kbps? How about 500 bps? Whats the
lowest you could go with the song "Boulevard of Broken Dreams" by
Green-Day?

No it doesn't. If you try and save an MP3 at 20kbps it drops the
sampling rate to 11kHz.

You're talking about MP3s. I am talking about WMAs -- which clearly do
allow a sample rate of 44.1 khz with a bit-rate of 20kbps . There is a
significant difference between WMAs and MP3s.

It will only do that if it converts to mono; hardly a like-for-like
comparison. 32kbps is the minimum for a true copy.

So don't stream audio at low bit rates; it is an inappropriate
application of an inappropriate technology.
