Software frequency response meter?

[k00zk0]

I just got a new mp3 player with a 7-band EQ thats fairly good and I'm wanting to set it up the same way as my pc is outputting. I can hear right away that its not exact when i approximately set the values the same as in foobar2000's EQ. What I want to do is plug it into my line in and use a program to acquire a frequency response graph of some white noise or a sine sweep playing from it. I'll then record the same sound playing through foobar and adjust the mp3 players eq until its the same. Question: Does anyone know of an app that takes a damn WAV file and generates a freq response graph of it? I've googled and found some but they all bug and glitch to hell.. don't give me a graph, crash, or even give me different graphs of each analysis of the same damn file. I can't trust that now..

Any input appreciated. Thanks.

DC6 demo will do 59 seconds of audio at a time.. It has an FFT function that works pretty well. DC6 will also generate white noise and sine wave sweeps.

Spectrum Lab will do it too but is considerably more complex.

I'm already marrried, but could possibly arrange an affair

So anyway, how did the actual sound turn out?

Is it sounding the way you want it to sound?

Well I haven't actually done it yet because with three computers I have in my house, two have a dead sound card, and you can say the same for the one on my primary laptop... I was soldering an amp WHILE plugged into the damn audio out/line in selectable port... touched the +12V to one of the channels..DOH!

I'm using an alternate sound driver that lets me use the mic port as an output.

I guess I'll be able to get it fairly close.

I hate the fact that my best sounding phones have to be so damn huge. Hopefully I'll mod the headband on my MDR-XD400 into something that doesn't act like an emergency upside-down pogo stick...

Well, I've visited a friend and done it. I just recorded the white noise output of my pc and then the MP3 player (Samsung YH-J70J) with sound recorder at high quality and then used DC6 to analyze the recordings.

The blue line is the mp3 players output overlayed over PC's before I corrected it. Mind you the values where you see the line dipping and spiking between 400 and 1000hz were actually set evenly to -10db on the mp3 player.. goes to show how inaccuracies exist when you may think its alright. I'll recheck tomorrow and make sure its even now, although I can hear it's almost correct. It's still not as brilliant cause I'm missing output at 18.5khz+ on the mp3 player (not in my control).

Portable Ayreon and Dream Theater never sounded so good

Thanks all.
