Thread: MONO to STEREO

  1. #1

    Default MONO to STEREO

    im working on a rush short film project right now and the only tool i have for audio recording is a lousy powershot a510 dig camera which has a mono output. the rest of the film is recorded in stereo, the dig camera ill use to record for background music and voice overs. will the mix of mono and stereo ruin my film? if yes is there a way in adobe premiere pro to convert mono to stereo?

    You have two solutions here. The first is buy a Mono to Stereo convertor plug. Stick the mono plug into the camera and then stick the other mono end into the Stereo convertor plug and then plug it into the sound card socket (can't remember if it's Line or Mic - try both to see which one gives the best sound). The second solution is creating left and right mono in Adobe Premiere, click on the mono audio track in the timeline to highlight it. Next click on the Audio Effects folder to open it. Then click on the little triangle at the side of the Stereo folder to open it and scroll down to you find FILL RIGHT. Click on it and drag it onto the audio clip you just highlighted and release. Now play the audio track and you should see both left and right (Mono) audio tracks in the sound levels indicator.

    What Nikosony suggests will give you two (left and right) tracks in mono, so that you get the same sound out of both speakers. It will avoid sound just coming from the left (or right) of the image and will sound much better than sound from just one side.
    If you're asking if it's possible to convert mono into true stereo... such that you get two different (left and right) tracks. The simple answer's no.

    It can (sort of) be done with lots of work in an audio editing programme but it involves a huge amount of copying, filtering, tweaking and such. Despite all the work, it never sounds right though.

    What you can do is "cheat" a stereo image by recording two separate "wild tracks" of the amosphere at the location.
    Copy the mono recording onto the left and right tracks (as Nikosony has described) then add one "wild" track underneath the left mono, the other "wild" track under the right mono.
    What you'll end up with is the original mono track coming from both speakers but with softer "background" noises coming from left and right speakers. The fact that each speaker is slightly different will "cheat" the listener into thinking he/she is hearing stereo.

    In days of old (ie the sixties) it was common to have one instrument coming from the left speaker, another coming from the right and so on.
    (listen to the start of "California Dreaming" from the Mamas and the Papas to hear what I mean).

    Nowadays the "norm" is to have the main audio (talking or lead instruments) coming from both speakers, with only minor differences between the left and right. It's not so "impressive" but sounds a lot more natural. If you go to a concert, you don't hear particular instruments just in one ear (unless you're really, really close to the front) do you?

    So, to answer your question. If you're only recording one instrument it won't sound funny to record it in mono, providing that it comes from both speakers. However... If there's anything as well as the one instrument, then recording in stereo is worth it because it gives a "spacial" element to the reproduction.
