How can I adjust my audio?

I am using CCCC codec pack.

We find on most Avi recorded with Dolby sound voices are too quiet and we have to bumb up the volume then when there is a loud bang it blows the roof off.

I am not too sure about the AC3 settings.

We are using a HTPC to play through to a kenwood Amp using Spidf

Help with tweeking the sound would be appreciated.

Cheers

Try switching between Direct Sound and Wave Out in MC's options for playback.

Hello
Thank you for your quick reply.

What I meant was how do I work out which settings I should use in the AC3 filter.

Cheers

Typically in a multichannel sound set-up, the dialog is passed through the centre channel. There are a few options that you can use.

First, in ffdshow audio decoder or AC3filter, or whichever filter you're using for sound (since you mentioned AC3filter, I'll use that example):

Go to the 'Mixer' tab and increase the Gain on 'Voice'. This will boost dialog, so you don't have to increase the volume to hear it. It leaves the bass and surround channels untouched.

OR:

In the 'Main' (default) tab, enable the 'DRC' checkbox. This stands for Dynamic Range Compression. What this does is decreases the playback volume range. That means, in general, quieter sounds are played more loudly, and louder sounds are played more quietly. Therefore the difference between the quietest whisper and the loudest explosion is less dramatic than the default in the movie file. This feature is also known as 'night mode' or similar in some AV receivers.

Hello

Sorry to be a newb but how do I do this in CCCC codec pack?

I have opened the settings in that program and can see nowhere to change these settings only boxes to tick.

Cheers

Sorry, I use standalone filters and not codec packs any more. Isn't AC3filter part of CCCP?
Look in the start menu under all programs. DO you see AC3filter listed there?
If so you can launch AC3filter config and make the changes there.
Or, if you have AC3filter selected within CCCP, just play a movie that will use AC3filter - and within MC's display view you can right click and select DirectSHow filters. If you see AC3filter in the pop-up menu under Directshow Filters, you can select it and it'll take you to the AC3filter configuration screens that I described above.

Hello,

Played the movie as instructed.

Right clicked and opened the direct filters which opens them in the task bar.

clicked on AC3 filter but no settings appear I can only tick or untick the AC3
Thanks

[fitbrit]

Okay, I think I know what the confusion is. I'm talking about an AC3 filter called AC3filter <- notice no spaces. I find it to be the most configurable one.

This is what I* would do:
Disable AC3 and DTS decoding in CCCP - is it ffdshow?
Do a search for AC3filter 1.51. Try Google
Download it.
Install it.
Use it for AC3 and DTS decoding.

You will see all the options I've been talking about.


* You may choose to do anything you want, of course.

when you use cccp, it might be that it uses fdshow audio. when it does, play a movie, rightclick on it go to directshow filters. and choose fdshow audio decoder. you get a list with a lot of options, choose and enable volume at the left. here you can set the volume for the channles. you could choose normelize, and set the overall volume higher, and playaround with the slider for the front channels.

Hello Fitbrit,

I have installed the AC3filter and Disabled AC3 and DTS decoding in CCCP

When I put it on SPDIF you cant change the volumes if I untick you can change the volumes.

I do not get Dolby unless I have SPDIF ticked.

What am I doing wrong??
Cheers

Using SPIDF sends the sound digitally to your amplifier. It's assumed that you will change the volume using the remote, or controls on the amplifier/receiver. You do have a multichannel AV receiver don't you? If you're decoding the sound and sending it via an analog route, you should be able to change the volume using your computer's controls.

Hello,

What is a multichanel AV receiver?

If I use SPIDF does that mean I cant change the voices to be louder.

Cheers

[fitbrit]

What is the sound coming out of? The TV? Or lots of speakers around the room? If it's lots of speakers around the room, what are they connected to? Also, if there are terms we use that you don't understand, it'd be a lot faster to help you if you looked them up on google first.

Hello,
The sound is coming from a Kenwood Multichanel amp.

Cheers

[fitbrit]

If you use SPIDF you can do what I've suggested with AC3filter. You can increase the 'voice' signal. Please just go back and read my first post about what you can do with AC3filter. On the other hand, you should be able to increase the volume of the centre channel sound on your Kenwood amp. Oh wait, you DO have a centre channel speaker don't you? If you don't, that might explain a lot.
