MP3 - Tech / Re: Completely confused over these Spectrum readouts?! Encoding MP3

EAC and Audacity both use LAME so you should be able to set them up identically.

Yes I am am aware of this, hence my confusion with the different readouts, I was expecting them to be the same, that's why I'm confused.

Audacity doesn't rip CDs.   You could rip to WAV and then convert the tracks individually to MP3 with Audacity (or some other conversion program).

Sorry my bad, I'm also aware of this.  I meant I am importing Flac or Wav files in to Audacity.  EAC you can encode to MP3 straight from the CD.. maybe this is what is causing the difference in readout and possible quality difference?!

Frequently, I end-up editing some of the metadata with MP3Tag anyway.   (And of course, most CDs do have the same artist on all tracks and it's the only the various-artist CDs that you'd have to change.

This just isn't practical for me.  They are compilation CD's and have multiple artists.  This is what caused me to try and find an alternative, i.e. Exact Audio Copy.  Purely because it's much quicker for the quantity I need to do and having to edit all the metadata manually would literally add hours to the task.

BUT I'm still predominantly interested in the final audio quality, hence my hesitation.  Just to clarify I am doing this for pub/bar djing and with what equipment I use and my workflow Lossy is my only option.  For other types of DJing I do I only use Lossless formats.

Thanks for your reply,
Steve

General - (fb2k) / Re: Undo tagging operations

Just imagine Word, Excel, PowerPoint, Photoshop, and about 90+% of current software, without an "undo" function.
They are applications used to create. Then you need undo, and you want multiple undo levels (and you want multiple clipboard elements ... damn Microsoft).

For a DAW, (multiple) undo would be essential. A media player has a different scope. In fb2k you can surely undo before saving, but that is all.

That said, I would have welcomed an undo for not only tagging, but for moving files.

Sure Porcus, that would be a nice workaround... in the meantime, while hoping for a real solution. :)

Thank God the developers of all those apps didn't think that "undo" would be a "niche fringe request" !
They didn't poll their user base asking if that would be useful. They just assumed it would be.
And actually I'm pretty sure that half of the planet was impressed the day the "undo" function was invented.

You know, nowadays there are "good developing practices". Like having a clear and efficient code, etc..
I'm pretty sure that having an "undo" function is one of those "good developing practices". Something that users simply "expect" to find in any half-good software. And fb2k is more than just a "half-good" software. It's a damn good piece of software !
Except for that "undo" function.

But don't trust me : I'm not a developer, which means that I know absolutely nothing about anything in the world. ;p

I'm just a guy who likes to think that he sometimes has good ideas, is all.
But funny thing, I've rarely seen one of my arguably good ideas be adopted by a developer in rational terms.
More often, I've seen them be discarded by developers in irrational terms.

Like "if it doesn't exist, it's because people use software in a different way".
Sure, people walked before the wheel was invented. People used boats before planes were invented. But was that a reason NOT to invent wheels and planes ?

Or like (and this is the best irrational argument ever) "why don't you do it yourself ?"
Well, maybe because it's actually NOT my job to be a developer ? What if I was, say, a nuclear physicist working @ LHC ? Why wouldn't you come and try to do MY job for a change ?

Truth be said, those things have more to do with some developers' EGO than with rationality and pragmatism. I've seen a lot of devs develop stuff because it helped themselves, rather than developing stuff because it would help a lot of other people. I'm not saying all devs are alike. I'm just saying some of them are. And that is a hard truth.

MP3 - Tech / Re: Completely confused over these Spectrum readouts?! Encoding MP3
Last post by DVDdoug -
I'm pretty sure someone could make a file compression algorithm that makes great looking spectrums at the cost of sound quality... 

MP3 is lossy, but it tries to throw-away stuff you can't hear.

EAC and Audacity both use LAME so you should be able to set them up identically.

If you have a good-sounding original, good-quality MP3s should sound GREAT through a great-sounding system!   But, nobody is forcing you to use lossy compression.

it just repeats the 'Artist Name' from one of the tracks and copies it over to all the other tracks.

3rd Party Plugins - (fb2k) / Re: iPod manager
Last post by TheEmpathicEar -
I may need more up-to-date documentation. I am using this. But, this does not have "Allow the use of sort order metadata fields from tags" [which I hoped might help] in the Database tab displayed on my foodop v0.70fb2k.
I checked the box for this. I found the "Load library". But, could not find "Update Metadata on IPod"?? [Where the heck is this??] I am trying update everything and not individual tracks. So, I just did the "Rewrite database". 1. I don't know if this process will help my specific issue in my post above? 2. Or, if missing a step here means it will not work?

MP3 - Tech / Re: Completely confused over these Spectrum readouts?! Encoding MP3
Last post by greynol -
From our rules:

TOS 8. All members that put forth a statement concerning subjective sound quality, must -- to the best of their ability -- provide objective support for their claims.  Acceptable means of support are double blind listening tests (ABX or ABC/HR) demonstrating that the member can discern a difference perceptually, together with a test sample to allow others to reproduce their findings.  Graphs, non-blind listening tests, waveform difference comparisons, and so on, are TOS not acceptable means of providing support.

Put simply, those graphs are worthless.

MP3 - Tech / Completely confused over these Spectrum readouts?! Encoding MP3
Last post by Steve18 -
Hi,

I am a DJ and I am wanting to rip some CD's to the highest possible quality MP3.  I wanted to do all of this in Audacity as to what I can see it gives the best quality encoding, well from looking at the attached Spectrum graphs anyway?  Basically I can't use Audacity as it seems when I 'multiple export' it just repeats the 'Artist Name' from one of the tracks and copies it over to all the other tracks. I asked Audacity support and apparently you have to do every track separate, doesn't make sense to me lol!

Long story short, I have started using 'Exact Audio Copy' as this copies all the correct metadata over.  I have set it up to encode externally using the LAME encoder as I was under the impression this was the best to use quality wise.  I have EAC setup to High Quality/320kbps.

When running the final copies through SPEK I am concerned that Audacity is giving a better quality copy than EAC.  See the much more definitive line/shelf around 16kHz.  Obviously being a DJ I am running these tracks though big PA sound systems and I want the better quality copy... Can anyone more experienced with this please advise???

Thank you so much,
Steve

General A/V / Why does LAME cut off frequencies differently for CBR and VBR ?
Last post by leonsk -
This is mostly out of curiosity. I'll leave some screenies from Spek.

The original FLAC:
Spoiler (click to show/hide)
CBR 320kbps (-lowpass 20.5):
Spoiler (click to show/hide)
V0 (-lowpass 22.1):
Spoiler (click to show/hide)
I'm mainly interested in the difference between CBR and VBR from 0:00 to 0:50, I'd appreciate it if someone could explain this (preferably noob-friendly).

I just realised I've posted in the wrong section, sorry. Could a moderator please move this ?
