AviSynth isn't the best audio processor. It's much better with the visual side of frame rate conversion. Its other strong points are: dealing with interlacing correctly, resizing, pseudo HDR, and improving how the clip looks (denoise, deblock, dehalo, sharpen, ect...). It's something I play around/code for with in my spare time. Check it out, you might like it :)
