Title: Oscilloscope for fun
Post by: Le québécois on December 01, 2011, 09:42:17 PM
I recorded and exported tracks of guitar on my computer as wave file. Ten minute ago I was listening to one of them in windows media player and I found in the visualization option a scope. Select it and you see your pure sine wave (not so pure  :o) flying around as the song is playing. I saw the chorus effect (offset of the wave) that was cool! 
It can't replace a real scope but for one who don't want to invest in scope it's possible to just record your bypass signal and compare it against your stompbox signal to understand what happen.

OK, I ear some of you saying, doooo It's there since windows 95? maybe? If you knew sorry to disturb ;)

I used to do this all the time when I was listening to Kansas City Internet Audio, the KCIA1 "radio" station.  I kept looking for a Fourier Transform and there might have been a frequency analysis pattern on one of the visualizations, but it looked more like amplitude on each channel of a ten-channel EQ than a real FFT (Fast Fourier Transform).

But I used the scope visualization until they went to a different bit rate and WMP couldn't handle it.

> I kept looking for a Fourier Transform

There are several "techie" displays in Media Player. Yes, they seem to be more decorative/amusing than precise.

I found the spectrum tool on the Adobe Audition software, its cool, not only for view, you can edit selectively

That spectrum tool is just about the only reason I'd ever buy SoundBooth.

Audacity has a FFT viewer too but it can't edit and needs some manual tuning in the options to be useful.

Tskk .. i never ever bought any of my editing software ...
That includes photoshop CS5 , vegas 10 and after effects CS5  :icon_mrgreen:

  IT works anyway though, I use it to analyze my arrangements and mixes, the 'better' ones to listen to make more interesting and diverse patterns appear, it seems [or maybe my mind is more open when the tracks playing are ones I'm already more fond of...

I used to use alot of the plugins for Winamp. Tiz the Shiz, IMHO. Some of them are written by people just for being able to have that accuracy. I used to use a couple spectral analyzers after recording to give myself an idea of what kind of post-mix adjustments I needed to make. Basically I could see the places that needed EQ'ing, which took a ton of time off that process (gets me to some kind of baseline before I have a chance to wear my ears out for the session).

Free, open source, tons 'O fun.

AIMP is a good alternative too , get the visualization pack ( on the russian aimp original site )
Compatible with WINAMP's plugins .
