[linux-audio-dev] Re: fast linear resampling on ARM - suggestions?

So ok, I can't use floating point - guess I missed that information.
Thanks for the heads up, Erik!

I tried to understand the original resample (JOS)  sourcecode which
also has a linear resampling besides the filter resampling. But I am
still not sure how I can use it to resample my 16bit mono
sample-stream instead of reading data from a soundfile. More than
strange enough it shifts the read data down by 8 bits before doing the
resampling operation on it. When it is done, data is shifted up again
by 8 bits to write it to a new file.. I cant understand why it does
that and if I can use my 16bit stream without the bit shifts..

I also googled for linear resampling sample codes in c - but found
none... maybe I searched with the wrong phrases.

So, if somebody is willing to give me a hint on resample, I would be
very happy!
