What's uncompressed audio?

Question

i just wanted to know....what is it...does it sound better or what...plzzzz help...

thank you!!!!!:p

Answer 1

Try using FLAC - Free Lossless Audio Codec instead of MP3 it will give you a sound equivalent to your original CD.

Answer 2

CDs are uncompressed audio. On computers, that would be .wav files usually. A song can easily be 50MB. So to make them smaller, we compress them, removing useless parts, and we get an mp3 file. There are other formats but this is the most common one.

Now, you can compress a wav in many different ways in choosing how much data per second you want the song to contain. If you choose 128 kilobytes per second, you will get an okay song, but it will be smaller than if you chose 320kbps. At 320kbps, I really don't think you can tell the difference with uncompressed audio unless you really, really, really want to, and have the equipment to do it.

Answer 3

uncompressed audio is like a wav file. you hear wav files all the time. The ding and the tada files that windows plays are uncompressed wav files

does it sound better than a compressed file like a mp3 of the same resolution?

The answer would be No

What the difference? The main difference would be the size of the file.

An uncompressed wav of the same resolution as a mp3

44 KHz  192kbit/sec would be huge at least 5 times the size of a mp3

Answer 4

Uncompressed audio SOUNDS BETTER - even on iPods! (if you have a decent pair of headphones, not the crappy ones which come with iPods).

Answer 5

The ONLY uncompressed audio that you could possibly listen to would be Digital Audio Tape. CD's are STILL compressed audio...and anything on a computer is compressed.

Answer 6

It doesn't necessarily sound better.

It's audio in it's raw format. When a compressor compresses audio, a lot of them have different algorithms, removing certain parts of the audio in order to make the file size smaller. The algorithms try to remove the most amount of "unheard" sound, but you might be able to notice if you had $1000+ sound system.

Uncompressed audio most likely will sound better, but unless you have that amazing of equipment, you won't hear the difference.

Answer 7

Believe it or not, even DVDs and CDs use "compression" to get all the audio (and video) information to fit on the disc.  In the music industry, scientists spent a lot of time seeing how much audio information they could remove from digital studio recordings before the average person would notice.

Even though the DVD audio signal (Dolby Digital) has a higher "bitrate" than Blu-ray Disc's (uncompressed PCM), the audio information is only being transferred at 684kps (kilobytes per second).  The "uncompressed PCM"  is being transferred off the Blu-ray Disc at around 6,400kps (or 6.4 megs per second).  This offers almost 10 times the digital audio information over standard CDs and DVDs.

The long and short of it is, similar to the way a compact disc sounds better than an MP3,  the uncompressed audio signals on Blu-ray Disc out-perform CDs and DVDs.  And just like CDs and MP3s, the average person wouldn't notice without an "A and B" comparison.  You don't know what you've been missing until someone tells you.

I was perfectly satified with standard "Dolby Digital" and "DTS" soundtracks on DVD until I heard the difference.  The moment you switch the audio during playback it's like all 5 (or 7) of your speakers are suddenly twice as far away from you and the ceiling of your living room is twice as high.  For the first time ever, you can listen to an EXACT digital copy of the studio master without ANYTHING removed.  CDs and DVDs, with their limited space, can't offer this.

The other "myth" with uncompressed audio is that it's impossible to acheive without spending a lot of money.  This is not true.  The audio technology with Blu-ray Disc players is completely BACKWARDS COMPATIBLE with just about ANY pre-existing stereo system.  The reason hardly anyone sings the "praises" of uncompressed audio is that virtually no retailer or Home Theater enthusiast has it set up correctly.
