A quick video I knocked up (sorry about the typo) to demonstrate the vast difference in quality between the ultra efficient open source Vorbis codec and the outdated, but more widely used, MPEG 2 Layer 3 audio format, encoded with LAME, the highest quality MP3 codec.

I recommend watching in HD for the best results, YouTubes 240p gives only 64kb/s MP3 so you won't hear any difference between the three versions, 360p and 480p will do OK but won't give total transparency.

As Vorbis uses an average bitrate, to make sure the comparison was fair, I used an average bitrate with the MP3 version as well.

As can be seen on the spectrogram, Vorbis cut's the top off at 15KHz while MP3 cuts off around 10-11KHz. Although there are some noticeable differences between the original and the Vorbis version (pre-echo, mainly) they are far less unpleasant to listen to, than the ones in the MP3 version (chirping, mettallic ringing, and an 'underwater feeling').

I've done all the processing and uploading losslessly for the best quality, doing so ensures transparency in HD mode.

ogg is better than mp3, FLAC and other lossless are better...

which is better: WMA 64 kbps or OGG 64 kbps?

vorbis 500kbps(ffmpeg) is like flac

OGG vs mp3 is unfair, it compares most to AAC (mp4)... Still damn impressive, after a few tests I'm converting all my stuff to Vorbis 96kbps and can't hear a difference... For all the random albums I don't really care that much, I'm doing even lower to 64k, the little thing is a beast xDDD

Vorbis works differently than MP3. It's a totally different and new technology.

Ogg vorbis best!!

MP3 truly a shit.

The mp3 at 64kbps sounded dull, whereas the ogg vorbis was nice and crisp.

...
OP's OC

When you're so poor and frugal you have to compress your library to 32kbs. This is me.

...
deadmau573

audiophile like me, ogg wins... mp3 sucks! of course flac still the best, but i'm saving some space for my hard drive, so stick to ogg...

...
ZhekaTrololo

Please, do Vorbis vs AAC comparison!
I've tried myself with 96kb/s bitrate and I think Vorbis is better.

But what about higher bit-rates?
(192 through 500kbs)

How does ogg Vorbis compare to AAC (encoded on iTunes)? I think iTunes is the best AAC encoder and agree w/ you that LAME is best MP3 encoder.
Lastly, I'm not familiar w/ ogg, so what is the best OGG encoder?
TIA!

Ogg Vorbis is overall much better codec than MP3.

...
Jose Juan Rivera Reyes

Lol LAME mp3 is lame.

Hmm... 16 bit equates to a maximum dynamic range of about 90dB with dithering. 24 bit gives about 144dB (only 120dB is practical IRL because of inherent noise). Our ears can perceive up to 120dB so it may be worth releasing commercial audio at 24bit once the loudness war has died down.

...
Magic Monty

Audacity.

what software is this?

It is almost impossible to hear a difference at that bitrate, I'm under 20 so my hearing is very good, but I still cannot discern the difference between 320k MP3 and lossless/wave. The only two times I have ever heard a real proveable difference between a 320k encoding and the original was with a 2nd transcode, and a high quality recording of African drums. Vorbis would perform much better than MP3 at high bitrates such as 320k +, but hearing the difference would be near impossible.

...
richerite

So by extension is Ogg Vorbis better than an MP3 encoded @ 320 kbps? Will you hear a difference at that bitrate?

The way our ears work without exceptions in any human. It is not recommended to go beyond 48k sampling rate for playback. No one has golden ears (this is a myth)... Some people just practice and take the time to discern differences only between loosy audio and lossless. Going to 96k or 192 is unnecessary, it is a waste of space, time if downloading and money and sound worse than 44.1. 24/96 is only used in the recording for padding. About how much we can hear 16bit covers it all. Cheers!

...
Magic Monty

Also, LAME already supports sampling rates of 48k, although it is wasted on MP3. If you really want to hear a difference, try a lossless format!

...
Magic Monty

DVDs use a 48k sample rate. It doesn't matter really as the difference between 48k and 44.1k is neglegeable (you won't hear a difference. Period.). What you probably heard was the difference between the lossy and lossless compression schemes used in DVD (AC3 or MP2). Comparing 48k and 44.1k using the MP3 format instantly renders any test invalid as the cuttoff of the encoder is around 20KHz at it's highest setting. Anyone who says otherwise simply doesn't understand Nyquist sampling theorem.

...

Bitrates are pretty terrible nowadays, MP2 is only good at 256kbit/s or more and the channel with the highest bitrate (Classic FM) at 192kbit/s sounds terrible. Most people with a decent sound system care, but most channels are now mono, and most DABs are cheap single speaker 'kitchen radios'. My trusty FM reciever with outdoor directional antenna can beat any DAB system, but its still sad that theres no real hifi broadcast system in use. Freeviews pretty rubbish too, HD is the way to go.

...

Sky set the trend with Sky (SD) Digital pitched at low bitrates that viewers happy with VHS tapes thought good. More channels through the pipe; so more money. That led to the blocky, solarised images on Freeview SD. Sadly, I bought a DAB tuner for my hifi years ago when the bit rate was decent; now it sound like a digital I-Speak-Your-Weight-Machine with AM dynamic range compression applied too. (Most) People don't actually care.

...

I don't think lossy storage for audio has that much of a future, to be honest, as hard drive sizes are increasing to the point where it doesn't matter that much anyway. But it has it's applications in streaming and broadcasting where bandwidth may be limited. DAB is just a joke though, MP2 is highly outdated and ofcom does nothing to regulate the bitrates, because they're useless, and the bitrate is disgustingly low. I never have nor ever will own one.

...
6dBperOctave

Lowering fs is an obvious bit-rate reducer. There's a lack of detail in the public/web domain about what Vorbis does with/about fs. All interesting stuff. Sadly, more of the population are developing noise related hearing impairments from gigs, clubs, portable audio, cinemas, etc; so bit rates can get quite leisurely in future, and no one will notice! But, with today's large portable storage media and increasing transmission rates why risk the quality? (Ans: commercial reasons: eg DAB!)

...
Magic Monty

Thats true for linear pcm, but then again, that is based around the sample rate. Lossy codecs don't tend to resample until you reach very low bitrates (such as 32kbit/s).

...
6dBperOctave

. . . and to the anti-aliasing filters which define fmax.

...
Magic Monty

The codec's don't resample, they just chop the high end off. You'll notice that vorbis has higher efficiency so has the ability to retain more treble than the MP3 while still sounding acceptable, the cuttoff is also able to be a lot less steep, so sounds much less 'ringy'. On the lossless copy, yes, the cutoff is determined by the sample rate as it is effectively linear PCM. I spend a lot of time listening to different codecs and can distinguish differences now at quite high bitrates.

...
Magic Monty

Almost all lossy audio codecs at medium to low bitrates lose some of the high end, or at least have a lower frequency/temporal resolution in the high end. It's used as a tradeoff, if you kept it then the artifacting caused by less bits available for everything else would become more noticeable than the loss of those high frequencies. The efficiency of any codec at a low-ish bitrate roughly determines the cutoff. Brickwalling is a term generally applied to dynamic range compression.

...
6dBperOctave

The three segments seem to show brick-wall filtering at ~20kHz, ~16kHz, and ~12kHz (respectively). Am I not seeing the effect of applying sampling frequencies of 44.1kHz, 32kHz, and 24kHz (respectively) to the segments? Lossy compression algorithms, which are all based on psycho-acoustic models, don't usually affect the value of fmax; but the sampling frequency (fsample) does that.

...
Magic Monty

It's definitely a better codec but remember to use a bitrate above 160kbps or so for best results. Doing so will mean complete transparency with any source material. I have only used the lower bitrates to highlight the difference in quality between the codecs for those who have not trained their ears to hear artifacts, and to minimize the effect of youtubes compression on the overall perceived quality. There are very noticeable artifacts in all codecs at this bitrate. I never use less than 192k.

...
Magic Monty

Its pretty obvious.
