You are on the right 'track' Prashanth, no pun intended. AC3 is the way to go. And I have also used doom9 in the past.
To add to the software, may I suggest: Nero Editor & if you can get it , Adobe Audition, DVD to AC3 Ripper. --- In [email protected], "prashanth.palanisamy" <[EMAIL PROTECTED]> wrote: > > hi, > gr8 writeup dude ...would like to add something !!!! > about the software....(the hardware thing u said was greek and latin 4 > me...and gr8 u had the guts to cut the wires of your system :0) > when i did the voiceless bgms for some(Alaipayuthey,Tenali,Rhythm(was > just 2 good!!!),Padiyaapa ,Minsara Kanavu) > the basic funda as u said was to find a dvd ripper to convert it to a > audio format ...more specifically i converted the dvd vobs to ac3 > files (which can store all the channels of the movie and the software > i used is now in the dumps..)....and then use an ac3 to mp3 > converter(i used a software called headac3h...i think!!!) by choosing > which channels i wanted to downmix(either surround or front > channels)....the downmixing was a trial and error thing... > and i used the resources from this site to get me going... > http://www.doom9.org/ > > its been sometime since this site was updated but nevertheless it has > good stuff about this thing... > > hope i helped !!! > :) > > thnaks and regards, > prashanth > --- In [email protected], just me! <arrking4eva@> wrote: > > > > GREAT STUFF! thanks alot but those who use software can u guys pls > tell us wat softwares u use? > > > > Thulasi Ram <karokelip@> wrote: > knowledge showcased! brilliant!! > > > > appreaciate ur effort to share this to us Wasim! > > > > > > On Feb 19, 2008 7:49 PM, kaissiom <kaissiom@> wrote: > > Voiceless BGMs - Explained! > > > > I'm not much of any expert on this topic, as I happened to > accidentally or unintentionally discover the process of ripping > voiceless BGMs. There may be members on this group who have expertise > in this area who may be able to shed some more light on this topic. > Following article is my limited understanding of this subject, please > correct me if I am wrong. > > > > First, some definitions: > > * For the sake of discussion L refers to Left and R refers to Right > (speakers) > > > > Mono: Single channel (no difference in L or R speaker, both > reproduce one sound) > > L speaker = R speaker = One sound from both. > > [Note]: Rahman has been very disappointed that 'Kabhi Na Kabhi' was > recorded in stereo, but released in Mono. > > > > Stereo: Two or more channels (generally two channel, separate > recording/reproduction of sound, L and R) > > L speaker: recorded/reproduced separately > > + R speaker: recorded/reproduced separately > > = 3 different sounds possible: L sound + Shared L/R sound + R sound > > [Note]: Think of it as a Venn diagram: Both L and R speakers > reproduce same sound most of the time, but will also have variations > of their own.
