2lame/mp2enc confusion

[Hawk]

Please can someone help me out here

Ive noticed when I specify 2lame in the commandline Mp2ENC pops up when encoding??? Should it not display 2lame??

for example look below...Ive highlighted what i mean + in the GUI it also says MP2ENC in the guides the gui shows 2lame??

BeSweet uses mp2enc, aka 2lame <-- written by Albert Faber.
BeSweetGUI supports tooLame <-- written by Mike Cheng.

[Hawk]

Thanks for the quick reply

One more question, so is the MP2enc in Headac3e also 2 lame?

Hawk

[DSPguru]

yeap.

there isn't any tooLame.dll release.

[DSPguru]

tooLame v0.2k is released under LGPL, so i had created tooLame.dll.
now you can use both with BeSweet v1.5b16 (http://DSPguru.doom9.org/beta.html) :
for mp2enc, use -mp2enc( )
for toolame, use -toolame( )

inner syntax is the same, i guess ;)

Hi Dg,

I think I found a little problem with BeSweet 1.5b16 and toolame.dll. Here is the logfile:

I'm not sure, were the problem is, but it seems that the '-e' switch is ignored. This may be a potential problem when muxing the final audio stream for SVCD. I didn't compare both streams quality wise, though.

hi tiki4,
thank you for paying my attention to this bug! though, i believe this is only a display bug.
please playback the mp2 file encoded with tooLame.dll (eg. with winamp) and see if it indicates crc protection.

[tiki4]

Thanks Dg,

I didn't know how to find out about CRC is there or not. I'll do as you told.
