Icon4 Looking for some help clearing up some audio..

Hey all,

Last night I recorded a fundraiser for the local school here where a bunch of solo artists, bands, groups, etc. came together and played some songs in a 'CoffeeHouse' style. Video came out perfect, shot with a tripod and everything. Only problem is that when I plugged my mic in, I forgot to check the mic battery -- which was of course dead.

I had found a Digital Voice Recorder (Olympus VN-960PC) and a mic in my house before hand, and figured I would give it a try and see if it would record some audio. Luckily, that recorded the audio. However it is somewhat muffled and distorted, and in a .wav file about 100MB. I'm just looking to get this cleaned up and get rid of the hiss and make it sound presentable. They asked me if I would make a DVD and such, which I'm planning to do but this audio is an embarrassment.

They had the soundguy recording it, supposedly, but I won't find out until I talk to the organzier again which could be a few days. Anyways, I'm looking to use what I have at my hands right now, and make it presentable.

If someone could help, that'd be greatly appreciated. Not very inclined in the audio department, I tried a few things using 'GoldWave' and it still sounds rather..not good to me.

Thanks for anyone who's willing to help!

Upload a 30-60 second sample to somewhere like Rapidshare.

At 100MB the WAV is probably low quality and not even as good as a high bitrate MP3. I would wait until you talk to the sound guy and see if he has a good quality copy he'll provide you with.

Re: Looking for some help clearing up some audio..

Well, it's what I have now and it's what I have to deal with. I'm just looking to get some help regaarldess, even if it is crappy. The DVD will be made for a benefit/fundraiser kind of thing so it doesn't have to be 100% top-notch best quality, but it wouldn't help. Planning on using the mix whenever he gets back to me (some people that were there last night said it takes him awhile, he works on a lot of stuff...). Figured if this can get cleaned up I can put it as a second stream on there. I'm uploading a 10 minute clip, which ended up being 100MB with GoldWave....I'm thinking GoldWave up-converted it to a higher quality WAV but anyways, it's what I have to deal with so I'm just looking to get it cleaned up. With a 10 minute clip (one song that was played) I figure someone can try working on a full song rather than just a small sample.

You might as well be recording in mp3 with this kinda quality. With a total capacity of 128MB, as compared to an average show being 1GB+, well...you're not going to get anything good.

Hopefully the soundman can hook you up.

As I said before, I understand it's not good quality. But regardless, it's all that I have to use right now so if the sound guy doesn't come through, I need to use what I have.

Re: Looking for some help clearing up some audio..

What you refer to as hiss is distortion due to brickwalling. Your levels may have been OK, but the microphone or internal pre-amp in the recorder were overwhelmed.

There's really no cure, but I managed to lessen it a good bit using a tool for removing clicks & crackle from vinyl sources.

I knew the recorder wasn't going to be great, but I figured I'd give it a try. Thanks anyway for trying.

Planning on buying/upgrading to a good audio unit in the near future...heard Edirol's are the best?

It's not perfect, but it's a bit more listenable.

I use an Edirol R-09. The newer model is the R-09HR. Either one will be fine.

Tell them you got mugged on the way home and the only thing they took was the master recordings.

Re: Looking for some help clearing up some audio..

I tried adobe "clip restoration" on it -- better for the eyes only, the sound was just a little dulled.

heavily clipped audio is pretty much unfixable unless its momentary
