Hi,
I am not sure if this is the right fb2k-forum to post this question...

About the equalizer in foobar... one can change the bands in 1 dB-steps, which are very big steps. Feels like a surgeon working with an axe to me... even 0,5 dB-steps would be far too big imo.

How do you deal with that... is there another way to "shape" your own sound than in those really coarse 1 dB-steps?

Thank you,
Tom.

For me, the eq steps from fb2k are small enough. I used bandpassed noise (adjusted to fb2k eq bands) to get a frequency response from my crappy PC speakers that imitates the one of my Sennheiser Headphones as close as possible. For some of the bands I had trouble to decide which of 2,3, even 4 settings was best, because the audible difference was too small. (IIRC, ~ 1dB is the treshold of volume difference humans can hear.)

Anyway, you can use Garf's foo_convolve to 'clone' any eq of any software you want. Just run a Dirac impulse (1 sample click surrounded by silence) through the eq (e.g. by playing it back and capturing the output with total recorder), use a wave editor to cut off silence samples and use the resulting .wav as impulse file for foo_convolve.

Thanks for the response.

I guess those 1 dB steps were made for small PC-speakers in the first place, but if your PC is connected to a good stereo-system, it's far too coarse imo.

Thanks for the convolver-tip; sounds confusing and a bit complicated at a first glance (if one is not too experienced with that stuff like me), but I am sure if I search the HA forums, I find a kind of an easy step-by-step instruction how to use the convolver (means to do what you just posted).

Here you go:

- Take the software DSP (or DSP combination like EQ + Echo/room simulation) you want to 'rip', e.g. some 3rd party Winamp EQ and choose the settings you want.

- If the software has a .wav writing/diskwriting feature get + enable it (E.g. Winamp diskwriter). If there's no such thing like a diskwriter, get TotalRecorder or something similar to capture the player's output during playback.

- Get the zip attatched to this post, Extract the .wav file. (2 seconds of silence with 1 sample click in the middle (full scale), 44.1kHz stereo)

- Play it back (sending it to diskwriter or capturing the playback with TotalRecorder)

- Use a wave editor like Audacity or Nero Wave editor to remove silent samples from the beginning and the end of the resulting .wav file and save it. (In case the channels are identical, you can downmix to mono before.)

- Get foo_convolve, put it to fb2k components folder, start fb2k, move Convolver DSP to active DSPs and go to Preferences -> Playback -> DSP Manager -> Convolver. Click on "Load impulse" file and load the .wav you've created.

Now fb2k will sound exactly like the DSP (combination) you've used to create the impulse response .wav.

Thank you very much, that helps a lot!
