lame -vs- oggenc

Hello all,

I am using both to run a test of both encodders.

For mp3

Code:

lame -b <bitrate> infile outfile

For ogg

Code:

oggenc -b <bitrate> infile -o outfile

What I can't find a good answer to is what are the defaults for both commands. I want to compare apples to apples. So if one defaults to Variable Bitrate encodeing and the other defaults to Average Bitrate, then the test I am doing would be in error.

Also if you have any input on how a test comparing the two formats should be done, please post those as well.

Thanks,

Norm

If you want to get an overview about encoders, their quality and other info take a look at http://www.hydrogenaudio.org/forums/index.php?act=idx. There you can find lots of info about these kind of questions and good comparisons (that are done quite objectively).

hey im using lame too and im wondering if you can change the bitrate to higher than 128 the default?

It's been a while since I visited this. I think you can. Check out the man page on lame.

could i have a link to that please. thx

This is the best one on the internet I could find http://www.die.net/doc/linux/man/man1/lame.1.html

The most up to date one will be on your computer, just type

Code:

man lame

at the console.

nice link but it didn't tell me this: is there a way when making a higher bit rate like 320 to 128 to my songs. Is there a way i can do the whole folder at once or just one song at a time?

Code:

 ABR and VBR options:



-b bitrate

    For MPEG1 (sampling frequencies of 32, 44.1 and 48 kHz) n = 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320



    For MPEG2 (sampling frequencies of 16, 22.05 and 24 kHz) n = 8, 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 128, 144, 160



    Specifies the minimum bitrate to be used. However, in order to avoid wasted space, the smallest frame size available will be used during silences. 

-B bitrate

    For MPEG1 (sampling frequencies of 32, 44.1 and 48 kHz) n = 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320



    For MPEG2 (sampling frequencies of 16, 22.05 and 24 kHz) n = 8, 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 128, 144, 160



    Specifies the maximum allowed bitrate.



    Note: If you own an mp3 hardware player build upon a MAS 3503 chip, you must set maximum bitrate to no more than 224 kpbs. 

-F

If I am understanding you correctly the switch you want is:
#if you are using MPEG1

Code:

lame -v -B 320

Aparently lame does not support bitrates higher than 160 for MPEG2

Hope this helps

sparxxx13: lame will do only one file at a time. To do an entire folder of mp3s, you must write a script.

ubuntu-norm: did you get the answer you were after?
