Is there a way to either alter the coefficients of an existing FIR filter or design a new FIR filter, which can be used to convolve with the raw CD data in real time?? I would be interested in trying a Lanczos filter, which works great with image files- I'm very curious to see if such implementation would also work with audio playback.
Responses are appreciated!! Todd |

Todd  I'm pretty sure it can be done via Foobar2000 - get a CDDA reading plugin and the convolver plugin. The convolver plugin loads a certain impulse response (wave file) and uses it for convolution. But... What's your goal ? Lanczos is AFAIK for interpolation / resampling. It's probably less useful for audio. Better do "sinc interpolation" Funny thing: I'm currently working on a real-time-convolver in Java bye, Sebi This post has been edited by SebastianG: Jul 20 2004, 22:38 |
