    I have samplitude but havent got to deep into it yet.

    Is there a way to do this in Samplitude?

    If so can you explain it fairly easily?

    Thanks

    no, I can't. Cleaning up a noisey phone conversation can require a variety of tricks, some of them included in samplitude, some of them you just need to know yourself after a lot of practice and experimentation.

    First thing to check is clipping. Samp. (depending on the version should have a de-clipping function in the efffects panel.) Try the generic settings first and see what you come up with. You may want to "remove DC" as well, just in case something has crept in along the way

    A little EQ and limiting will help - after declipping, you'll want to make sure any rogue transients or spikes are reduced, so you can bring up the overall level. There may be some useles junk in the bass region as well, depending on the recording device.

    If there's line noise or AC hum, you can sample the noise (as it occurs in a region by itself) and put that on the clipboard for Samplitudes "noise reduction" applette. With a little experimentation, you may be able to get rid of some phone line junk as well.

    I'm not sure what this has to do with Mastering, btw. You may want to move this post somewhere else.....

    Thanks for tips Joe.

    Seems like I read about a method where take the info and phase invert it then recombine it that helps..Hafta research that somemore.

    Posting Forum;;I cldnt fig out where else to post it here. I knew some of you guys used Samplitude.

    I don't think inverting the phase - just by itself - is going to do much for you in this case. Samplitude 7 and 8 were pretty powerful as they were; I don't know what V10 carries, but I'll bet it's a lot better in terms of on-board tools.

    Declipping is probably your first step, when it works (and it doesn't always) it really does a lot for clipped material, but it depends on where/how the clipping happened. ALways worth a try.

    Mainly with a mono, lo-res phone recording, you want to just remove as much junk as you can, and hope for the best.

    Fortunately, you're working with one of the best audio tools on the planet, save for it's bigger brother, Sequoia.

    JoeH,

    I had a good time messing with it. Really liked being able to drag the freq value and loudness ard on the screen in real time. That enabled me to get close in 2 tries.

    Also, tried the diif male and female voices..
