Alrighty. My mom just recorded a 4 day lecture she gave in Texas, on some sort of recording device, and a microphone. Not important.
She asked me to put the recordings on her computer, so she can hear them, and I did. Only 6 out of the seven lectures she gave was on there, but that's not important....
I opened up the first one in Quicktime (it was an mp3 file), and started playing it. The lady introducting my mom was talking, and it sounded great. I fast-forwarded into the middle, and low and behold there is an awful loud buzzing noise stuck to my mom's voice. She was obviously talking too loudly too close to the mic, so her voice buzzes when she speaks.
Is there any audio editing software that can restore good quality to this recording???
