PandaBoard audio upsampling demos

This is to let people know I’ve just made improved versions of the
‘upsampling’ audio programs available from

http://www.audiomisc.co.uk/software/ARMiniX/Upsampling.html

These fix some bugs and include some improvements to get better results.

There are two programs:

!DRPlayer = allows you to play audio using higher quality upsampling on
modern hardware that can support the higher audio sample rates.

!WAV_Upsampler = allows you to generate upsampled wave files.

Given modern hardware like the PandaBoard – as used for the ARMiniX and
PandaRO – these allow much better audio quality to be obtained. However
they are mainly written as ‘demos’ so people can see what is possible and
how it is achieved. Hence the source code is included and anyone who wishes
is welcome to use/modify it as they wish.

Just to update this. I’ve now released ‘new improved’ (I hope) versions at the same address. These have an additional choice of conversion filter.
