I have a stereo track that was recorded in a dslr camera using a lavalier mic. The right channel has all the voice information (along with a lot of noise) and the left channel has only noise. I tried to invert the left channel to see if it would cancel the noise from the other channel, but it didn't help. But I don't know if I did it right. Do you think there is some way I can use the noise information from the left channel to help me clean the channel that has the actual information I need? If it helps, I know this noise comes from the camera. It's a constant hiss in both channels.
