Title: --verbose output of all --quality settings
Post by: Artemis3 on 2002-11-09 19:24:54

--quality 11 calls MACDll.dll (why not flac?)

So are you saying all quality levels (besides 11) automatically use xlevel coding?.

They don't. I think he just wanted to be a good boy and appended the --xlevel switch.

BTW Artemis3, what did you post this table for?

Oops, yes i used --xlevel, simply ignore the "+ Xlevel" part

What for? Information maybe? Reference? Seemed apropiate...
Its interesting to compare the current values, if nothing else.

Not to sound harsh, but this information is superfluous for newbies, and advanced users know how to use --verbose... also, will you keep this list updated each time a new beta comes out? No offense, just stating my opinion

--quality 11 calls MACDll.dll (why not flac?)

I thought that was meant as a joke... In the sourcefile there was only a message to the user "Can't find macdll.dll" and then it set quality to 10 when I had a look. Has it changed so that it actually workes now? Or are you only joking as well?

Hmm.. you have some point there.

However, imo we are going to the wrong direction, if information can't be published because of the fear of newbies. And anyway, it seems that there's not that kind of newbie tweaking tradition with MPC. MPC users seem to be generally more educated than your average Joe Xing-user.

I haven't done the table that Artemis made with 1.14 (haven't had time/enough interest). I have done it with older MPC versions. I'm just saying that I personally found it interesting, especially comparing the tmn/nmt value development through versions.

Imo what should be done instead of blocking information because of the fear of newbie missuse, is to educate people with few sentences like "these values are likely to be changed in the next versions" and "mpc presets are already highly tweaked" etc...

Another choice is to make newbie restricted areas, which means that newbies can't even read certain forums.

I think that the educational value of the table is not very high. Of course, it's valuable information for some, but it will soon become worthless, without maintenance.

Hmm, how should this be practicable... isn't it also a step in the wrong direction? I mean, we want to provide information to everyone, not exclude certain people.

of course, newbie restricted area, hiding information, is the wrong way.

So, if he would start a new thread with those verbose results, and comparing/collecting there the ouputs of different encoder versions, that could be interesting.
A kind of development history.

I think, it is not irritating newbies, as it is quite obvious, that the relevant, important, updated  information is contained only in the first post of the thread.

Lots of info becomes worthless/old in this business pretty soon. I don't think every information here has to be strictly educational.. If that was the case, this would be purely a newbie forum.

I also don't think that the table values are specifically "educational". But like I said the message could have contained some educational parts like "these values are likely to be changed in the next versions" and "mpc presets are already highly tweaked" etc...

Though granted, this specific thread (List of recommended MPC settings) was not probably the best place for that table.

I am a newbie to MPC (this time last week I was still under the impression that MP3 @ 128kbps was CD-quality).
I am quite intrigued by topics like this - even if I don't fully understand it yet. Reading any posts like these gives me some insight into how settings of a file format affect the recording of music. I am becoming very interested in sound/music and only just starting to delve into the depths of it really. I play guitar in a band, and one day I will need to know how to operate mixing desks, equalizers, compressors; know how to hear what frequencies are out in the mix and how adjust my settings on the run. Audio compression is also an interesting topic when it comes to sound and music playback from my PC which I use quite often. I only have about 4000 MP3s at the moment, so I figured before it gets much bigger - I might as well research formats that are going to sound better through better equipment and hight volumes than my PC speakers (as I'm sure most backing tracks, track recording, interlude songs etc will be played from a PC rather than CD in the near future).

So please, don't stop talking about these files for our sake. Truely, everyone is a newbie once - we have to learn. Teach us, pelase.

I found the table interesting.  I don't see any reason why not to post it.  If newbie's can't understand it, then they can ask questions: thats what the board is for.

I thought that was meant as a joke... In the sourcefile there was only a message to the user "Can't find macdll.dll" and then it set quality to 10 when I had a look.

I like this one. 
And this --q 11 really inspired me, so I did --q 20, and, yes, it produced a --q 10 track.
I didn't realise that encoders (oggenc as well) have such triggers to switch back to max available quality, if you mess with q settings.

Thread split (was originally in "List of recommended MPC settings").

This is now officially your thread, Artemis3!  ;)

Ok... hmm maybe i could update only when a release is made? The betas come too fast

Also i wonder, should i paste new results or replace the current ones? I could paste the results from older versions, i do noticed many interesting changes among versions. Maybe enlarge the first post with past results? that does not sound good...

results sorted by past versions are very fine.

perhaps put the newer versions at the top.

What about quality 5.xx or 6.xx?

--quality 7 --xlevel --verbose

yields 22000 Hz as maximum encoded bandwidth for v 1.14. Is there any problem with the encoder I am using?

Not if you are using a 44.1KHz source.

Hmm, pardon my ignorance. But how on earth do you find 48 KHz sources ?  Do you rip DVD audio or something? Or does someone have a studio?

Why does the insane profile raise the highest frequency encoded in that case? Is there any relationship between the sampling rate and the highest frequency in the sample when it comes to encoding?

My 48 kHz files are recording from vinyls or tapes, that I made with my computer. I prefer using the DAT deck as an external digital device for playback/record, than my soundcard, because it has CINCH analog in/outputs, instead of jacks, it has more headroom in the analog input (the soundcard clips), and an analog level setting.
But it's an old consumer deck, that only allows to record in 48 kHz 16 bits (short play), or 32 kHz 12 bits (long play). No 44.1 kHz available for recording.

Using a 44.1 kHz sample rate allows to record (in lossless mode) frequencies until 22.05 kHz, and 48 kHz until 24 kHz (N kHz allows to record until N/2 kHz). Other frequencies are not defined in the digital representation.
