Thoughts on Live EVP and DC6 Software

Several years ago, I was monitoring over speakers with a microphone in another room. A manís voice faintly said, "Do you want to speak to Chris?" and louder, a young man said, "Hello Chris, this is Chris Ö yeah!" The man then said, "You need to speak up. Do you want to try again?" Then the conversation faded out. That started me thinking and experimenting with live EVP sessions. What I needed was software that would do the filtering live. Searching the Internet, I found a company named Enhanced Audio, with a computer program called DC4, which is now DC6 (Diamond Cut Six).*
DC6 is an audio editing program just like the ones we use for EVP (Audacity, Audition, GoldWave), except it has a neat feature called "Live Multi-Filter." With this feature, audio coming into the computer can be filtered live and the result heard with a short delay of a second or so. A typical setup for EVP would be a microphone into the Microphone In jack of the computer with DC6 Live filtering what comes from the microphone and the output playing on the headphones connected to the computerís Headphone Out.
DC6 is available as a free demo from the Enhanced Audio website. It wonít stop after a month or so and has a sixty-second limit on the file size it will process. This is not a problem for EVP clips. File saving is disabled but there are workarounds. For instance, the Live Multi-Filter output that youíre monitoring will save as a wav file (up to sixty-seconds). [A DC6 license is $159 online or $199 for a CD.]
To configure a personal computer so that the input sound is directed to DC6, open the SOUND AND AUDIO DEVICES program in the Control Panel, select the AUDIO tab and click on the SOUND PLAYBACK VOLUME button. Select all of the MUTE check boxes except WAVE and PLAYBACK. Click on the SOUND RECORDING VOLUME button and select the MICROPHONE check box.
After downloading the file from Enhanced Audio, installation is simple: Just keep clicking OK. To get started, install a microphone at the MICROPHONE IN jack and set the Windows RECORD and PLAYBACK boxes as described above. Use either a headset or speakers.
Open DC6 and select the LIVE MULTI-FILTER and click the PRESET tab, find LIVE CONTINUOUS NOISE FILTER, click it and it will appear in the MULTI-FILTER window. Then click LIVE PREVIEW. If all is well, youíll hear your voice after a short delay. To record, click LOG OUTPUT. Remember that the trial version of DC6 will only record for just less than 60 seconds. Each time you make a live recording youíll have to exit the LIVE window and open it again. With the full DC6 version of course thatís not necessary. Keep the master volume down until you are familiar with the routine. You donít want any acoustic shocks when using headphones.
The simplest use of DC6 is as live denoise. The default filter settings are not optimum for what we do. The main thing is to get the software working and get used to it. There are several of us using it and results are being posted on the forum, so ask there for help. The hope is that live conversation with our spirit friends will be forthcoming.
