    Hi guys, I dont know that much about audio , I am more a video guy. I am making a video for a friend in costa rica and I hired a costa rican sound guy to make the audio..... It is terrible. ohmy.gif

    He recorded the levels VERY low and there are some sort of cicada's or locusts making a high pitch hiss in the background. I am now back in the states and looking for any way I can salvage this audio to be used for an online only video. Keep in mind I work in final cut and only have the audio filters that come stock (apple & fcp)

    here is a sample audio clip so you guys can here it, what filters should i use?

    Avid

    THANK YOU ALL SO MUCH IN ADVANCE!!!!

    it doesn't sound that bad to me. typical b/g noise for a remote done outdoors with ambient noise.

    You can export the audio to be used with better software and then import the fixed audio back into FCP.

    well basically the client (even though he is my friend) isn't happy with the audio so I need some advice on what filters to try? someone told me maybe the graphic EQ and a low pass filter? or maybe high shelf? does that sound right? I tried it and it seemed to cut out the cicadas but made them sound as though they were in a small boxy room if you know what i mean

    Most of the noise is around 8.5kHz. That's also fairly important for vocal clarity so cutting that range with filters will affect the voices. You need something a bit more sophisticated to reduce the cicadas without harming the desired content. I fooled around a little and came up with this:

    Honestly, that background noise sounds like ambiance to me. It's not bad at all. In fact, I think it adds to the sound. If you are in a tropical area, these noises are common. They are part of the environment. You can't change that. Editing that out is going to do terrible things to your dialogue IMHO. You'll need to convince your client of this. It really does sound fine.

    Define a "quiet" area that exemplifies your definition of noise... apply... done.

    Thanks everyone, I'm thinking about lowering the cicada's just a little then lightly adding some birds and stuff so it sounds like it's supposed to be like that. Thanks again...

    there are some noise reduction programs that sample a part of the audio where there is no one talking and then applies some algorithm to remove the noise without damaging the audio. usually when recording on location the sound person will record 30 or 40 seconds of background audio to accommodate the n/r program.not sure how well it works or what it's called.

    I tried to get rid of most of the background noise, but due to its loudness (compared to the dialogue) the voices lose a lot of tonality and start to sound "boxy".
    There was also a lot of low-end rumbling from handling the boom or the wind hitting the micorphone┬┤s diaphragm.

    Kurt... it's called Izotope's RX... what I linked to above.

    It's extremely comprehensive and deals with "noise", clicks, pops, and electrical "hum".
