Title: fix audio saturation
Post by: dsanchez on June 08, 2007, 21:22:55
Hello

Yesterday I used for the very first time my iRIVER IHP120 Audio Jukebox (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=300114395541&sspagename=ADME:L:RTQ:US:1) in Robin Guthrie's show here in Lima (Robin Guthrie is a former Cocteau Twins member).

Unfortunaltey, it seems I recorded with a high volumen, and now the audio is too saturated (attach a sample)

Is there a way to fix this?, or at least improve it a bit?

Where I can change the volumen-recording settings in this IHP120? Crowby? :)

Thanks

David.

There was a similar topic when A.D.L.'s recording of Taormina had similar problems:

It was concluded (on another forum?) that there's really not much you can do. :?

You can try adjusting the EQ a bit. That could get rid of some boominess, but it's not going to take away the distortion.

What kind of mics were you using? Some can't handle high volumes at all. However, I'm sure there's an input level on the recorder. You did Rockbox it to handle WAV and make it a proper recording device, right?

Unfortunately I didnt have time to buy proper mics, and so I just used a simple "Olympus" mic  :lol:. I will go to local-bands concerts to improve this.

I don't know exactly what you mean with "doing RockBox". I just press the button to change to WAV and record. But I didnt find anywhere where to adjust the volumen level thought...

Yeah, I seriously doubt that mic is meant for recording loud music. ;)

But you're definitely going to need to "Rockbox" the player to make it a proper recording device. I'm just assuming this will add more functionality, such as levels adjustments, etc.

I Rockboxed my iPod to make it play FLAC. It took a while for me to figure out, but it was worth it in the end. Bye-bye iTunes! :twisted:


I found this at www.rockbox.org. This is the software meant for your player:

There should be instructions in the zip file. Good luck! :rocker

David,

I never tried recording before I Rockboxed my iHP-120.  My recommendation would be to Rockbox it.  My device is now setup so when I turn it on it's pre-recording.  This shows me the levels of each channel without actually recording.  Nice feature so you don't waste HDD space.  Try doing this during the opening band.  If the meter is clipping you just need to press down on the dial until both channels are selected, then left to lower your gain.  Once I'm set all I have to do is hit the record button on the left side and it starts to record.  Be sure to watch your levels for a few songs to make sure everything is going smoothly.  Once you feel comfortable with everything it's recommended to lock the device so you don't accidentally hit a button.   

A few other things.  Yes, you should get a different mic.  Sounds like you are going with Giant Squids.  They are a great starter mic and I think you'll be happy with the results.  Do get a battery box from another dealer, though.  Also, make sure you are plugging into the optical line in.
