This solution, without using any low pass filters before and after the
desimation, will generate a lot of aliasing frequencies, Kjetil!
Here is another solution:

Maybe this will give you an idea:
48khz -> 8khz:
float get_output_sample(get_input_sample){
static int i=0;
static float sample;
if (i % 6 == 0)
sample = get_input_sample();
i++;
return sample;
}
8khz -> 48khz:
float get_output_sample(get_input_sample){
float ret = get_input_sample();
for(int i=1;i<6;i++)
get_input_sample();
return ret;
}
Not the best sound quality though.

Were you expecting real-time/time-critical resampling or offline?
