Title: testing esnips programme for mp3 soundclips etc.
Post by: alfafalfa on November 17, 2006, 01:25:07 PM
I have been trying to find a way to let people listen to some samples of soundclips that give a clearer insight in the issues discussed here. For example the noise I experienced with my Rebote 2.5.
So I am just testing.

Sorry for the terrible sound . I just discovered that when you change a perfect sounding wav file into an mp3  I get this horrible (digital ? ) wobbly distortion.

Anybody know how to convert it without this. I used Cool Edit. I have never had this problem but it's also the first time I have done this. I always go the other way round , from mp3 to wav without any trouble.

Will try again.

And one more thing : the TC chorus soundclip is not mine.
I just chose it because i have a TC.

This one was already an mp3 so there's no problem.

When you convert it to MP3 make sure to use a higher sample rate. Try 128

Just changed the sample to a higher rate of 128 .
I thinks it sounds better now.
This was my first attempt to record acoustic guitar with a Panasonic Capsule and a schematic I found on the net. I am not very satisfied with it.
I have a small sample where there is this nasty resonant peak.
It could be possible that this setup recorded some higher harmonics of my Collings guitar.

For accoustic Gtr recording try this:

Place the mic about 5 inches from the 12 fret. Then you can angle the mic either towards the soundhole or up the neck a little.
Did you use an Omni directional capsule or a Cardioid/unidirectional one?  If you built the Uni one you will have to fight off some of the bass and resosnance because the guitars body is so big and flat. It's a trial and error thing. The main thing is too avoid the sound hole area with a Unidirectional mic...

Recording acoustic is not an easy task without a good mic. I have built a few Panasonic capsule mics (omni) and they are pretty nice for the $20 (or less) they cost to make.

John,

I used the Panasonic P9959-ND Omni-directional capsule because it was recommended in an article.
What schematic did you use and  could I have it please ??
Normally I like to record my acoustic guitars directly from my acoustic preamp into a mixingdesk.
This gives the best results . The preamp has a high headroom because of the symetrical power supply of of + and -  15 volts.
I have recorded with a Beyer N 201 mike and a Senheiser 441 both rather good mikes but if your room acoustics aren't perfect it's (in my case) never as good as a direct recording.
The mixingdesk has the same sort of powersupply and Neutrik transformers at the input.
