Can't play MP3s

02/08/2003 - 06:00 por Doug | Informe spam

Hello to all, and really, a lot of thanks to all ahead of time who take the
time with resect to this problem. It is quite the serious one, and I have
no idea how to go about solving it, or even what could be causing it. I'll
try to be very descriptive...for more details just ask:

The Problem: I can't play MP3s clearly on ANY player, including winamp 2,
2.09, 2,9, 3, Windows Media Player, or RealPlayer. As a matter of fact I
get bad quality on avi's as well, divx inclusive. What I mean by clearly is
that if I'm playing a song lets say, the music is loud and clear, but the
singers lyrics can hardly be heard. Basically, the song sounds as if it
were recorded in a church where the echo would drown out any words in the
song, and actually, this echo is there. It sounds really weird, and I must
admit it's very hard to describe.

The System: Pentium 200 Mhz, yes its old, but all worked fine 1 month ago
(I've posted with regards to this problem before, but then when I thought it
wen't away, it's back now...fresh after an all complete system reinstall),
32 megs or RAM. Like I said, it played mp3's fine 1 month ago, and I have a
Pentium 133Mhz with 16 megs or RAM playes MP3s just fine!

Actions taken up to now: as I stated, this problem occured before, and then
went away again. It was suggested by a few that this problem could be
caused by add-ware shipped with kazaa. When the problem again came back (2
days ago), I finally decided to re-format the entire system (fdisk, format
...the whole nine yards), then installed win95 and win 98 (clean and from
scratch). After getting win98 installed on the system, I installed the
basic drivers for sound card, network adapter, video driver, and then tried
winamp. And to my complete surprise, the same thing happens, the song/audio
file, etc.. playes really strange, with a sort of echo in the background
with the lyrics drown out by the instrmentals (almost as if the "lyric
layer" was decreased in volume while the "song layer" was increased in
volume - if that's making any sense). Then I tried Windows Media Player
6.4, and the exact same thing occurs, can't play avi's, mp3... (didn't try
other compressed audio formats). It does play cd's, but that of course is
no surprise as playing cd format cd's isn't all that difficult for a cd-rom.
I should also mention that when I play these songs on any player, my
processor activity does not rise above 5%, thus eliminating the possibility
that the old pentium is having problems keeping up with the decompression.
Also, I was suspecting the sound card, but as already mentioned, I can play
cd's just fine...

Well, that's all I can think of which seems relevent for the time being...

Well, not exactly, dadiOH. The signals on cassette and open reel tapes

(and 8

track) were analog in nature. Same thing was true for records.

Well, I blew it again. :(

I think we're all speaking of the same thing but confusing each other cause
we think the other is speaking of something different...so hopefully to

clarify:

Everything in a computer is stored digitally, by which I mean, using 1/0's.
Of course
what this digital data represents varies: On a regular cd, the digital data
represents
analog format information so that it can be interpreted by a cd player, on a
casette or 8track

the same thing happens, everything is still 1/0 except this time magnetic,
representing analog information.

No it's not. The magnetism on the tape is analog in nature - continously
varying in strength (amplitude) - and NOT in discrete ones and zeros. The
same thing is true for the record grooves. Analog - NOT digital.

Waves on the other hand are again digital (1/0)

"Wav" stands for waveform, typically a complex mix of sinewaves, which are
analog. They are *converted to PCM (digital) format, and THEN stored on the
CDs (in the pits) as a digitized representation of the original analog music
waveforms.

I never used samba, so I cant tell you anything about it.

Just a quick question about libraries in linux though. When installing
these
I usually compile them while logged in in my user account and then simply
move the *.so
files into the /usr/lib/ directory with root priviliges...is that all there
is to it if
you lack certain libraries? (it's late and I'm too lazy to read about it
now...although
I'll probably will have to give the library know-how a read sooner or later)

I always installed libraries thru the package manager, so the
system knows whats installed and not, rather than just moving .so files
into /usr/lib/. Any libraries I've needed have already been in binary
form, and have been easily available from the various Mandrake contrib FTP
sites.

When I come across an app that I got to compile, I install it with
'checkinstall' rather than just 'make install', the tells the package
manager that another application has been installed, and makes later
removal much easier.

So as you said:
"What's on a CD (or a tape or a hard drive) is digital...a numeric
representation of the analog sound".

And as such its in analog format of course encoded "digitally".

Heck,

all that computer can understand is
1 and 0, so the sounds are basically sort of fourier analysis stored on

the

cd.

Repost
(sorry didn't post to all groups)

OK I had a similar problem that took ages to figure out, Music appeared to
play ok but vocals were either nonexistent or muffled, Movies played the
sound track, but vocals again were muffled but occasionally came through
load
and clear, very puzzling! And the solution so simple: the output from a
sound card feeds L+R with a common earth return. The earth return on my
system was defect and so vocals which are usually centre biased (stereo
speaking) were cancelling out and what I was hearing through the speakers
was actually the difference between the L+R channels (i.e L-R.)

Try this experiment: play an audio cd (try something with widely separated
L+R channels like Mamas and the Papas California Dreaming ) and listen to it
through the headphone socket on the front of the cd player. Now compare this
to the output of the sound card. If you have good stereo separation then
you'll have to look else-where. If the sound card output is basically L-R
then check the speaker/headphone plug/wiring

P.S Audio output from a cd is analogue, and is fed to the soundcards audio
amplifier via a small 3 or 4 wire cable not the wide flat cable used to
transfer data. Yes there are digital outputs available on cd players and yes
when you rip an audio cd the raw data is transferred via the data cable.
This scenario is based on the most common connection used between cd players
and soundcards.

Hope this helps

G.
