increasing volume with tooLame / TMPGEnc

[theDruid]

Hi,

does anyone know some commands that you can add to the path for tooLame in TMPGEnc (when using tooLame as an external mp2 encoder) to increase the volume in the final mpg? Is there a gain command?

I'm making VCD compliant mpg's from DVD rips, but the volume always comes out really quiet. (I use SmartRipper->DVD2AVI->VFAPI->VirtualDub, then frameserve into TMPGEnc with tooLame picking up the wav produced by DVD2AVI, by-the-way).

A quiet source with the volume turned right up never sounds quite so good at playback & I'd like to be able to increase the volume of the audio in the mpg without having to de-mux/edit audio/re-mux.

any help appreciated! - any other suggestions apart from commands for tooLame?


cheers,

BeSweet allows you to set gain. Get the gui and experiment until you get the correct command line and then copy it into Tmpgenc with the proper excape variables for input and output.

thanks for that - I'll give it a go when I've got some time!

hi - i'm back to this one again - i was searching on how to add commands/switches to TMPGEnc when you use tooLame / SSRC as the audio engine, and I came back across this thread.

I found out (via BeSweetGUI) that SSRC can do 2-pass normalisation by adding switches.

e.g. "C:\Program Files\SSRC\ssrc.exe" --rate 44100 --twopass --normalize [..then the files]

..but, my question is, how do I add these switches to SSRC in TMPGEnc?

I've tried just adding them to the path (under Environmental Settings -> Audio Engine), but this throws an error.

Any bright ideas please?

cheers,

PS. I'm using the latest TMPGEnc 2.11, but I don't have 'Plus' - just the MPEG1 version.

You're making your life far too hard. You have no need to frameserve via virtualdub.

DVD2AVI frameserves to TMPGEnc by itself. Also DVD2AVI will normalise the volume of the WAV file it decodes for you as well ! Do a F8 before you extract the audio.

Then in TMPGEnc, open the m2v file as the video source, and the WAV file as the audio. Encode away.

Much easier & quicker.

Hi Scumbag,

yeah you're right - if you look at the dates the original posts there were from last year.

If I'm ripping from DVD now, I'll got straight from DVD2AVI into TMPGEnc, using DVD2AVI to downmix the audio & normalise it.

I'm still really insterested in how to get the switches into tooLame / SSRC in TMPGEnc's audio engine for when my source is already an avi.

I really want to cut out any other steps, as if I could get TMPGEnc to switch on SSRC's 2-pass normalise, TMPGEnc (in batch mode) would be able to the whole lot.

thanks for you suggestions anyway,

mcdruid.

8) I may be missing something but what about the audio edit boxes in tmpeng surely they will do exactly what you want? I always increase the volume by x2 using this even though I use sscmp for an external audio. Are you saying this is having no effect??

[theDruid]

thanks RabidDog,

I must admit I haven't tried the normalise under 'audio edit' there

However, as many people have said that TMPGEnc's own audio processing is not as good as the external tools tooLame / SSRC, I'd still like to find out how to use switches for these utils.

Point taken though - I'll give the internal normalise a go.

Thanks again,
mcdruid.

it must have worked becuase you havent replied... I think the audio proc in tmpgenc is pretty good.. I will check out other ways just to compare quality..which audio encoder gives the best dynamic range?? I want to make some music svcd, so I will try other audio encoders.

[theDruid]

he he - yeah sorry; that's a bad habit.

I think the normalise in TMPGEnc's not too bad - and there's something like it in VirtualDub now as well I think.

I've now settled (pretty much) on always exporting the audio, and using SoundForge to normalise - that way you can see clearly if just one loud noise is getting maximised, and the rest of the soundtrack is really quiet.

You don't really have that luxury with commandline stuff (or the simple functions like TMPGEnc's).

I still stick to using tooLame/SSRC as the audio engine in TMPGEnc though - although I have read that the built-in engine has improved a lot.

Just out of curiosity RabidDog, how did you find your way back to this topic? It seems to have been brought out of retirement a couple of times!!

cheers,
mcdruid.
