5.1 Audio; I can see one definite speech channel. Can I cancel it out?

May 5, 2012 4:01 AM

Aspiring soundtrack composer here.

I've imported a movie with 5.1 audio. Here's a screenshot:

Can you see the channel with the red arrow?

 

It's by far the highest when there is only speech, it's about the same as others (or lower) when there is no speech. Is there a way to mute one channel? or mute all the others and leave the speech?

    I beleive that the standard mixes for 5.1 audio all involve a centre front speaker which carries all the major dialogue. Edit: larger mixes susch as 6.1, 7.1, 9.1 etc as well as dual sub arrangements (5.2, 7.2, 9.2) all carry this channel in the common arrangements, not seen any without it.

     

    What precisely is the end result you want with the audio? In effect muting this channel will cut all noticible dialogue, muting everything else will leave only speach.

    With 5.1 Source Material, you can use Break Out to Mono for that Clip, from the Project Panel, and then adjust the Center Channel, as needed.

     

    If I did not understand your question, then please ignore my comment.

     

    Good luck,

    In order to re-write the music myself, a musicless soundtrack is ideal.

    If I could mute the music and keep the speech (and sound effects), that would be very helpful.

     

     

    I've found that if I export the 5.1 audio from premiere to a 5.1 .wav format, and import it into audacity, I can control each channel separately.

    Only one track includes the speech, but unfortunately it also includes a heavily filtered version of the music.

    If you guys know a way to filter the music from the speech channel, I could easily have a speech-only soundtrack!

    If you have Adobe Audition, it has many ways in Multi-track Mode, to handle "karaoke," or the reverse.

     

    Some possible tutorial links are HERE.

     

    Good luck,

    You're much better off finding some local filmmakers who need a music track for their projects than trying to do this.

    Alright thanks everyone. Here's a method I'm quite please with. I recommend it to every guy who wants to practice composing music for movies.

     

    1.Convert the file to .mp4 with Handbrake, while keeping the surround sound.

    2. Export the audio only with Premiere.

    4. Keep only the speech channel with Audacity.

    5. Move the aformentioned channel through a "keep vocals" effect in GoldWave.

    6. Import the speech only alongside the original soundtrack to any audio editor (I use Cubase), and use the speech-only track only when there is speech and music at the same time. Remove the music-only sections from the OST, and keep the natively speech-only sections.

     

    Viola. Happy composing.

    Sounds like you have a plan and a workflow.

     

    Thank you for sharing.
