'evening

I've been slowly moving some of my favorite CD's over to Mp3 recently, encoding in batches using RazorLame (source files from EAC). I've been using -b 320 -m j -h, with no problems so far. This last CD, however, I accidentally encoded using -b 320 -m j -h --resample 48. They play the same as the others and sound fine on the PC, but get horribly chopped and distorted on an Intel flash Mp3 player. Does anyone see a problem re-encoding them straight from the 48kHz .Mp3's to 44.1's? Or is there an advantage to 48's significant enough to warrant ripping a new set to 44.1's for the Mp3 player? It is my favorite CD; I wouldn't mind a double set for just this one.

Many thanks,
Kazix.

there is no advantage of resampling to 48000 in lame. just delete the 48khz mp3s and rerip/encode at 44.1khz from the cd.

What floyd said is correct. Resampling is pointless.. you won't gain any quality. The possible exception might be if your soundcard resamples to 48khz also.. but then I'd simply suggest using foobar2000 with the resampler, or Winamp2 with the SSRC output if you don't like doing that.

Reencoding from a 48khz mp3 to a 44.1khz is a bad idea.. quality will suffer quite a bit from doing this.

Also, I'd suggest using --alt-preset insane... it'd provide higher quality than the command line you are using.

Many thanks for the pointers/information. It's relativly easy to just get the disk out again and rerip/encode to 44.1, so I'll do that.

In the interest of educating myself, --preset insane translates to --nspsytune -b320 -h -mj --nssafejoint --lowpass 20 --athtype 2 -X3, right?

Best,
Kazix.

afaik, no it doesn't, in toggles some internal encoder switches that are not accessible by any commandline options. there is no way to translate any preset to commandline switches completely.

If I were you, I'd stop tweaking and just use --alt-preset insane, it is the best.

It has much better transient response than many other CBR 320 settings. There are several difficult samples which kill 320CBR to my ear, but not --alt-preset insane.
