Member audio_upsample_words (int16_t *input, int16_t *output_aligned, uint output_word_count, uint32_t step)

similar but the output buffer is word aligned, and we output an even number of samples.. this is slightly faster than the above todo we are currently limited to 4095+1 input samples step is fraction of an input sample per output sample * 0x1000 and should be < 0x1000 i.e. we we are up-sampling (otherwise results are undefined)

Class mem_buffer

This module needs to be checked - think there are issues with the free function

Must be more we need to say here.

certainly need an example
