How to pass mic through a software equalizer?

    I have a Heil PR-40 microphone which inputs to a USB interface, made by M-Audio, called FastTrack.

    Along with podcasting, I like to use the mic for making phone calls using my Vonage software phone called "Vonage Companion."

    The microphone is very bassy. It seems that some VOIP networks are using some kind of bandpass resulting in very poor quality phone calls.

    I'm wondering if there is some way to modify the output of the microphone to accentuate the mids and highs to my voice isn't so bassy. Is there some kind of software equalizer I can use to pull this off?

    I tried passing my mic output through GarageBand and then to Soundflower and then input that to my software phone but didn't have any luck getting it to modify my voice.

    Any other ideas? Thanks.

    Not sure if it will work, but you might see if something like Jack will help you route your audio.

    Why didn't running through the EQ in GB work? I'd put more work into getting GB to work.

    No clue. When I sent the audio to speakers through GB's monitor, my voice was changed. But sending it through SF and then to Vonage Companion did change the audio at all.

    Hi Nysus - it sounds to me like the extra bassiness could be caused by the proximity effect ... ie. low frequencies are accentuated the closer you get to your microphone. You could try cranking the gain a little and moving back from the mic as a less convoluted fix than the EQ idea.

    Cool, hadn't heard of that problem before. I am very close to the mic. Thanks!

    3 different suggestions

    (1) Buy an Omni mic - they have no proximity effect - but they are of course not directional. There's also directional mics that have built in lo-cut filters built into the mic on a switch.
    (2) Move further away from the mic you currently have like others have said
    (3) Put audiohijack on it and filter out the lower frequencies. (around 100 hz and below)
