Hey guys this is what I am trying to do:

I have audio recordings from my blackberry that have conversations on them. The only trouble is that there is music and tv playing in the background that really makes it hard to hear the voices.

Is it possible to lower or remove or do something to the music/tv sound in the back so the voice comes through louder?

Or who do I take this to to have it done because,full disclosure here, the voice on the recordings is no longer with us, so if anything could be done it would mean the world.

This question came from our site for engineers, producers, editors, and enthusiasts spanning the fields of video, and media creation.

Bell Labs once defined noise as "unwanted signal" with that in mind you might want to try the following with your Blackberry recording using a free download known as Audacity. I have used Audacity but not for these purposes so I do not feel completely comfortable offering this as a solution. However, since it's free software, and it should not take too much time to get a result you might give a try:

I also found this on Creative Cow:

You need to combine a number of tools to achieve this. It will probably not be possible to completely serperate the vocal. I use MAGIX Audio Restoration which I use for general audio restoration I often use its tools to widen the stereo image, seperate the centre and side channels even further. I then use bx_solo(free) or some other tool to ms decode the sound (seperate the mid channel from the stereo). Not a perfect solution.
