I need advice on using audio cleaning lab mx.

I am on a trial of the audio cleaning lab and I am trying to widen the frequencies to hear speech coming in on lower frequencies than usual. I am talking about being able to hear frequencies of -60hz or maybe I mean just 60hz. Somebody who knows audio will probably know which one I mean to say. I am using this for recording and listening to electronic voice phenomena. (and don't roll your eyes ) This program seems to be very good. I wanted to add to this question to try to help the person who tried to answer me but didn't quite understand what I wanted to do. By widening the frequencies, I meant make the spectral view go down to lower frequencies so I can view them. I have good speakers and a good digital recorder as well as a good mic for recording such things as spirit voices. (I do have audacity also, but it is full of static when I try to boost the sound) I needed to get a better program and this seems like it would work. I think I need to know how to use the equalizer and para equalizer better because from what I've read in the manual, this is where you can set the frequencies. I want to set them at, say, 20hz up to 20,000khz. Do you think that is something I would be able to do? And do you know how I would do that? I was just fooling around with an older recording that I knew had spirit voices on it and I was already able to pull up more voices that I didn't know were there so if I could really get those to those lower frequencies, I'd really be in business. I am not trying to isolate anything though, I just want to be able to see them on the spectral view and that way I could hear them play through my headphones. All my equipment is made for those frequencies of 20hz up to 20,000khz so I will be able to hear them. I appreciate you trying to help me before and maybe now with some clarification, you may be able to help me after all. I just couldn't figure out how to do those equalizers even after reading up on it several times. It was just confusing to me. Every sound program is different and I've worked with quite a few so they all use some different words to mean the same thing and I get confused. So if you can come back and help me again that would be awesome. Thank you very much.

I'd like to help, but quite frankly, the things you are saying just don't make any sense.

"Widen frequencies" - What does that mean exactly?

Your use of the equalizer suggests that you're either accentuating or attenuating certain frequencies, but you haven't explained what you've tried to do. Do you mean you're trying to isolate those frequencies?

To "HEAR" frequencies at or below 60 Hz,...

First of all, they have to exist in the source material. "Normal" human vocalizations do not extend to such low frequencies, but that's not to say humans cannot make low frequency guttural sounds.

Second, to "hear" them, you need to have audio tranducers (speakers, headphones, etc.) capable of producing sounds that low. If you're using tiny computer speakers, you not going to hear them properly.

Third, to "hear" those frequencies, your hearing has to be sensitive to them.

I think you're expecting too much from Audio Cleaning Lab. It sounds like you're trying to do things it was simply not designed to do. You might want to look into the freeware audio editing program Audacity. It is also capable of some basic spectral analysis.

What you are asking for is not possible with ACL.

It sounds like what you are looking for is a wide range audio spectral analyser which will have a very low noise base, distortion levels and high spec signal processing in order not introduce 'artifacts' into the boosted/widened audio spectrum.

You are talking mega bucks for such hardware/software.
