Mono MP2 from AC3 to VCD?
Hi there...
Does VCD compliancy include Mono-MP2s? And even more important: Can Headache output such a file? Any experiences? |
More than VCD, SVCD and DVD supports it with no problem. I did four KDVD this week with 10h of VCD program using 96 kbps mono audio on each.
I did that with besweet. I never use Headac3che. |
sometimes i use BeSweetGUI and it's good but
HeadAC3he results sounds better for me in musicals. i see posts in the forum from many people with headac3he problems.. and some more with BeSweet problems... i never did any problem with HeadAC3he ! :? Jell, HeadAC3he can do mono files easily! :wink: |
According to quality ....
HeadAC3he uses mp2enc.dll which can also be choosen i Besweet beside 2lame.dll .... but I never had bad experiences using 2lame.dll (maybe its just again a build thing?!) According to mono ... I also can't choose mono as output in HeadAC3he .. so maybe you got a newer version Jorel ;-) I always do use mono mp2/ac3 encoding for example in case of "classics" captures as they veeeery often do come in mono, so why doing encoding them in stereo?! :lol: |

Yep that would be nonsense if mono is provided by two channels 8O
In besweet I never got problems doing "real" mono encodings no matter if using 2lame.dll or mp2enc.dll as choice in besweet. |
8O :oops:
yeah, i see ! and the real mono can be used in the 2 channels with differents souces like: German in the right, English in left ! i never did it before cos i never needed that ! this is the idea ? (if is this the idea..) |

If your source is originally mono, then you can better do it in mono and not in stereo, you are right ? Okay, now, if you do it as two channel mono, let say at 112 Kbits, it's like you do it in one channel mono at 56 Kbps (56 * 2 = 112). Right ? :arrow: I do all my one chanel mono streams at 96 kbps; So I have a far better quality than you have with your 112 kbps 2-channel mono stream. And a use less space on the disc for that ! |

:mnkypile: fantastic option :!: |
But, when you set one channel mono, does the audio output for only one channel (left or right)?
I thought that mono has 2 channels with same audio in each one. But if you record in one channel mono, sound go out only for one speaker (left or right)? :( |
The st. VCD 2.0 can use:

Mono is Mono. Mono existed when Stereo didn't even cross from the brain of engineers and at this time, having one speaker was yet a miracle :-)
Mono will come out of the center speaker if you have a 5.1 system, or from both front speakers (L+R) if you have a simple stereo installation (or a stereo TV). |

If it's mono, keep it at mono, and encode at 64 (or 96) kbps. You will have the sound quality of 128 (or 192) kbps stereo using half the space. |
@muaddib: Well I guess I don't want my whole sound coming from the center-box and Subwoofer. :mrgreen:
I actually wonder why you can't make the receiver to play a the mono stream on L+R and on the Center at the same time... would that sound bad? btw: good to have you back! :wink: |
Jelly, you will have this simply by turning off your 5.1 decoder. Like when you are listening an audio CD : you put (or are supposed to put) your receiver in Stereo mode.
This way the center is not use and for sure, the sound from L+F as I explained ! Note : You can't have L+R+C with a mono signal as the definition of the center chanel (when you are not in discrete encoding like AC3 or DTS) is : the center receives the mono signal that is present on both L and R channels, and this signal is substacted from the L+R. If you don't substract it from L+R, you will have a signal a +3db (double of the power). |
jell,
today i change my signature and was wrote there: 10 speakers around the ears.... i have one simple 5.1 and + 2 stereo amplifiers (Akai and Polivox) see one of the reasons that i'm still using the stereo amplifiers: http://www.kvcd.net/forum/viewtopic.php?t=9439 if you don't want to read all the "conversation", (bla bla blas) go to the target with ilustrations: http://home.earthlink.net/~kantack/surround2.htm believe...amazing results...(ask Kwag about or read all the thread) my poor english can't explain better than posted there! complements..... if you want some "reverberations" effects in mono... http://sox.sourceforge.net/ take a look: * Channel averaging, duplication, and removal * Band-pass filter * Band-reject filter * Chorus effect * DCShift audio * Deemphases filter * Move soundstage to front of listener. * Add an echo or sequence of echos * Fade in or out * Apply a flanger effect * Apply a high-pass filter * Apply a low-pass filter * Display a list of loops in a file * Add masking noise to a signal * Pan sound between channels * Apply a phaser effect * Change the pitch of a sound file without effecting its speed. * Change sampling rates using several different algorithms. * Apply a reverb effect * Reverse sound samples (to search for Satanic messages) 8O * Detect periods of silence and start and stop processing based on it * Change the speed of samples being played (without effecting pitch) * Display general stats on sound samples * Stretch/shorten the duration of a sound file. * Swap stereo channels * Create sounds with a simple synthesizer * Trim audio data from beginning and end of file. * Add the world-famous Fender Vibro-Champ effect * Adjust volume of samples. and more.... :wink: |
