I need expert help on restoring audio from a concert.
The original source material was captured with a run-of-the-mill MiniDV consumer camera with a microphone that appears to not have been so good. The problem is that the audio of the video is raspy, lacks bass (low end) and rumbles/crackles/hisses at any point where the music seems to raise in volume. Any "emphasis" from the musicians results in crackles and dirty noise. My limited knowledge of amplifiers, frequencies, and recording would tell me that the problem is that the volume/gain of the recording was distorting the microphone's capability to capture the live audio. In soundforge, the peak indicators on the right were screaming RED, so I figured normalizing or compressing it below the RED would solve the problem but that just lowers the volume of the recording. If I compensate with more volume on the system, the cracks return.
I have Sony Soundforge 9.0 and I've tried my best to apply all types of different filters (the ones from DigitalFaq.com). I've tried normalizing, removing cracks related to high end, etc...nothing gives me what I'm looking for and maybe the issue that I'm new to all this and don't know what frequency to really lower to eliminate the dirty aspects of the audio stream.
I'm providing a link of a 1:10 minute sound clip of the entire concert in raw WAV format (15 megabytes). Could someone please take a look at the clip, attempt some filtering/cleaning up of the sound, and then post back what EXACT steps they took with Sony Soundforge 9.0, so I may replicate the procedure on the entire concert's audio feed? Thank you! This concert is probably the most important one I've ever performed in and it has immense sentimental value. Any help would be incredibly appreciated. If I can restore the sound to an acceptable range, I'm putting it on YouTube, so you're handiwork/advice WILL be seen online. I just need to clean up the audio, join it with its accompanying video file, and upload to YouTube.
