I think its important the samples be at the same volume, so dont think its necessary, since the encodes as well as the lossless would be at the same volume anyway.
 
But if the encoder does not use any replaygain..i don't see how that can happen. You can encode at different settings but the volume will stay the same for any given sample.

It's a nice thing to have, sure, stuff all at more or less the same volume.
 
I think LAME might be encoding properly. But since we are using foobar I don't see the point of not using replaygain.
 
Zhps, wouldn't it be better to keep it simple...just leave everything at default levels with no gain applied anywhere?

edit: just chkd, default setting on foobar playback setting says apply gainso i'll leave it as is :)

Though Slight chage of plans.

I moved the Mac back to my bedroom and the HTPC gets the b**ch rig running XP

So here is how it is going to work

volunteer gets a CD(s) of his/her choice

the CD(s) gets ripped to Wav or Apple Lossless

The CD(s) also gets ripped to mp3 320/256 CBR

Dbl Blind ABX test for the songs bought in + the following song courtesy I

- What it is - Mark Knopfler

- Come away with me- Norah Jones

- Alive - Pearl Jam

Any other song suggestions?

as for the setup,

foobar o/p in ASIO mode in 88200/24bit mode on a M-Audio Transit fed to Marantz PM17SA fed to Phase Tech Velocity V12



so who's the first bakra

bottle?

(actually 2nd, 1 st was Saiyan :P)
 
OT: Get a new cabinet re :P , even the zebronics Bijli will do ( costs only 1.4k incl. 400 smps ) :D

Did you miss the part about VBR ?

..thats whats been actively encouraged for at least several years now (when lame 3.90.3 came out in 2001!)

a v0 encode will take up less space than a 320 CBR and should be the same.

a v2 encode will approximate 192-256CBR.

Most ppl want to save space if there is no difference in sound.
 
hahaha...too much of an effort to move out the ol' b**ch from her ol' house to a new one

hmm..true, buut the idea here is to judge if there is any qualitative difference between lossless, 320 and 256 which (perhaps?) doesn get answered by VBR

else it'll be a comparison between lossless, targeted 320 and targeted 256
 
What is the reason for 256 & 320 CBR ?

You refer to them in the same light as i do VBR.

the only reason i'm aware those CBR settings might be used by some vendors is that typically CBR poses the least playback problems with the wide variety of portable players out there. But that's hardly a reason for personal use.

lol dunno, btw add my masta eddy to the list too :ohyeah: :cool2:
 
Equipment: Sennheiser HD650, Home built amp, Citypulse DA7.2x, Creative XFi

Song: Dire Straits - Private Investigations

A is Uncompressed WAV ripped by EAC, B is the same encoded by lame (latest) with VBR in best mode.

My score as of now:



Will try a longer series of tests later. Let me tell you its bloody hard and painful :P.
 
This on a track I am sure you are totalllllly familiar with :P

*foobar n00b warning

did you get ABX running in ASIO mode?

How?

The moment I choose ASIO as the output mode, ABX stops working
