In Encspot I noticed there is a quality index in the lame header tag. How seriously should this be taken?
I've read how it measures the quality settings that were used in the encoding process & I believe this is what determines this index. I've noticed this index is about 78 with alt preset standard. Yet you could use switches like -b 192 -m s -V 0 -B 320 -q 0 and get it up to 100. From what I've read, alt presets are always superior to any switches. Just wondering if anyone has thoughts or opinions about this.
I apologize if this has already been discussed & is a redundant post.
http://www.hydrogenaudio.org/forums/index....3381#entry33922The quality index doesn't take into account the code-level tweaks of alt-preset standard,extreme and insane.
In practise I wouldn't take the quality index very seriously, even when not-talking about --alt-preset standard,extreme or insane, simply because it expects everything to work ideally, which is not the case.

Thanks for the info.

Hi,
I’ve been reading different forums and recommendations about quality MP3 encoding for about 2 months up to now, but I still hesitate what switches to use. To be clear, my intention is to encode all my music in MP3 archive with best possible quality, but to be able (if I decide for some reason to do so) to decompress it again and write it to Audio Discs, without furthermore loss of quality.
So here are some questions for you:
1. Some people say “--alt-preset insane” is the best quality you can get from MP3 format (at least for LAME 3.92). Other people say “extreme” is better because of its “intelligence” during coding “simple” and “harder” parts of a song (e.g. “extreme” is better than “insane” in passing on the “stereo panorama”). What is the truth?!
2. Is there any official place where developers classify, in order of their quality, the LATEST, TESTED and STABLE switches (presets) for command – line? It is very confusing to me to see different developers recommending their own switches and to choose between them… Which is best!?
3. These days I understood LAME 3.93 have been released. Is it safe to use it, or should I wait for further tuning?
Thanks in advance for helping me.
Sincerely, George
