question about LAME and commands

2016-12-02 22:50:34

Hello, I'm using foobar to convert FLAC to mp3, mainly for the use of SoX resampler, but I do have a question about the Y switch, I've read that it's better to use it on V 0, and since my FLACS are HiRes vinyl rips (24/96-192) I do have a question if I'm using this code correctly inside the Custom encoder settings within foobar.

I choose Lame.exe which I downloaded from SourceForge, so, here's the code

-S --preset insane --noreplaygain -V 0 -Y --lowpass -1 - %d

in resampler settings I choose SoX to resample to 44100 kHz

I've been trying various commands and they all give me different sizes, let alone spectograms

I want to get the highest quality possible, without artifacts, can somebody orient me? A 843 MB album gives me a 81.9 MB size with the settings above. Is the -Y switch necessary? I've read this:
"

The Y switch prevents global gain quantization from being decreased solely to accommodate the needs of sfb21.
"

So what settings should I use to maintain the highest quality? Let me note that this mp3 is for playback and portable playback.

Cheers and thank you.

Regarding the -Y switch, preset insane is 320 CBR:

Also, --lowpass -1 makes no sense to me.

If you want to make use of the VBR algorithm and impose a minimum bitrate of 320 kbits just use:
-V0 -b320 --noreplaygain

thank you for your response, I mainly got my info from here:
sound.stackexchange.com/questions/38109/lame-why-is-a-lowpass-filter-used-with-preset-insane

and regarding the lowpass -1, if I use it, when I right click the file to check encoder settings, I do not see the -lowpass 22.1 activated, contrary to see it when I don't use that command, it displays this with the settings I'm using

"-m j -V 0 -q 0 --vbr-new -b 32", from MediaInfo v0.7.90

If I play with different commands it sometimes show -lowpass 22.1

So what do you recommend me to use?

Unless you can demonstrate that you can tell the difference through ABX testing:
-V2 --noreplaygain
