Is this slow for encoding an mp3?

[RSI]

40-60 seconds to encode an average length song from wav to 256-320 VBR MP3 using LAME 3.91 (using RazorLAME)?

I have a Tbird 1.333 (266 fsb variety), btw. It seems kinda slow to me, 40 seconds?

Sounds about right to me.

On my 800MHz Celery, the LAME 3.92 alt-presets work at about 2x real-time. Looks like you are getting 4-5x real-time so things are alright.

Thanks for the replies.

That's odd, I really thought it strange for it to take that long. Oh well.

i remember when it used to take 2.5 hours to encode an mp3!! on real time!!!!

seems slow my p4 1.5 ghz does 192kbs wma's in ~20 seconds, ive never done mp3s so i cant compare it for you.

Exactly, you can't compare encoding WMAs on a P4 to encoding VBR MP3s on a Tbird. Try encoding the same thing and compare... I wanna see if I'm actually getting reasonable rates here or not.

It will go faster if you are doing CBR. VBR takes more processing.

Your encoding times are about par from my experiences. Isn't the quality of Lame worth the wait??

Time for a faster processor..... On an unrelated note I overclocked my P4 1.6A to 2.4GHz. The speeeeeeed!

I think that sounds about right. My P3 1Gig does average length tracks in about 70~110 seconds (depending on the complexity) when using --alt-preset standard.

I want to say that sounds slow, but I can't say for sure...
