NOTE:
Now the latest CML compiled binary is included in the project rev11 boundle.
From now on, the latest version be put on the top.


ChangeLog:

rev11
fix 22050 output crash
all printf change to fprintf(stderr) [setup.c, bitallos.cpp, bitallo3.cpp]
ICL9 compile with speed increase (with a different name "hmp3enc.exe")

rev10:
Length bug found by level fixed

New compile with asm enabled, several small bug-fixes.

-V0 -X should give correct vbr-header now.


Edit: Uploaded the wrong file. Please Redownload. This time is OK

Edit2: second compile obsolete

The third compile. All asm optimization used. Slitly undeceivable speed increase can be expected.

Edit: This compile is recommended.

Edit2: Use "-U2" option to achieve better speed via P3 optimizations

Project files to compile

The whole thing here.

Problem: pow34.asm not used (don't know how to compile)

TODO: gapless plaback support (somebody can do this?)

Can you please provice VC6 project files too?

rjamorim,

I cannot provide VC6 project file. But I think it's not too difficult for you to creat one with all these sources in the uploaded package.

Regards,


Edit: My friend CML made a VC6 compile. But the result .exe file is bigger, while the speed is more slower than that compiled with VC7. I have no idea why.

BTW, the asm file need MASM to compile (pow34.asm as an exeption).

Thanks to my friend CML, who changed the asm code that cannot be compiled directly by MASM. Now all code can be compiled by VS7.

And some unused file (.c and .asm) is eliminated to keep project clean.

The whole package is uploaded here.

Helix mp3 encoder binary rev5

Changelog:

1). -hf switch description in -Help
2). other minor tweaks

Note: can encode high frequencies in low bitrate or low vbr_scale. (not a good idea, I know, will change to the default in next rev.).

hmm, tried to download rev7 and rev8 but downloads are corrupt here. FF and WinRAR. anybody else experience this?

This post has been edited by Digga: Jul 19 2005, 16:36

Works fine here...(FF & winRAR too). here is a link mirror if you want.

No problems here.

Get them at http://www.neilpopham.pwp.blueyonder.co.uk...p/mp3enc-r7.rar and http://www.neilpopham.pwp.blueyonder.co.uk...p/mp3enc-r8.rar if you want.

I see kurtnoise beat me to it. Rev7 here as well.

thanks guys, that did the trick.

rev9 (Project & Binary included)

A lot of small tweaks
Add -EC switch to show parameters used with the encoding

Thank you.
I want someone to up-load the binary to the Rarewares.

Will it take on magical powers then?

Cool!

Edit: There seems little point in releasing it to the masses until it stops being revised twice a day.

Following the requests for VC6 project files for this, you can d/l a complete cml version 9 source with VC6 project files in an 'hmp3' sub-directory, plus an executable compiled with VC6/ICL8.1 (but without any specific optimisations) from: http://homepage.ntlworld.com/jfe1205/helix_mp3enc_cml9.zip BTW, the executable generated is called 'hmp3.exe' just to differentiate it from the other binaries. You can call it what you like!!

Although I haven't tried, I am assuming that all likely optimisations for speed are already taken care of by the extensive asm code.

As already mentioned, not much point in putting this on Rarewares until it stabilises.

There's some known bugs with this encoder. It cannot take 22050khz & 11025khz files reported by Raffles. Can someone fix this issues?

Rev9 is quite clean and stable, I hope someone more specialized in audio science can take over the job.

,it's a mp3 encoder not a mp3 decoder.

CML's rev10

Length bug found by level fixed
