    nested for loops

    In Matlab I'm trying to find the nearest value of time1 to each value of time2 without going over the specific value of time2.

    Is there a way to speed this up? It's very slow.

    So I have two time bases: n1/44100 and m/48000, where n1 and n2 are integers. n ends at 176400, m ends at 192000.

    n2 = n1+1 (for...

    Re: Upsampling algorithm

    I see, I am not a proficient coder however, and am having trouble writing the actual interpolation algorithm.

    I could also upsample 11025 by 4x to 44100, interpolate to 48000, then downsample by...

    Upsampling algorithm

    Hey, I need to find an algorithm that will upsample from 11.025 kHz to 16.0 kHz. I am having trouble writing one. Does anyone have any insight or has anyone done this before?

    Regards,
    Dave
