I have been really impressed with the sound quality results using this sample rate converter.  Downsampling from 192/24 to 44/16 has given high quality results in terms of subjective listening, and I have also used it for upsampling 44/16 to 48/16 with excellent results. (I always use the highest quality setting.) If you really care about the audio quality of digital music and are using high quality files, I recommend using this converter.  I have tested it against most of the other well known options and I find it subjectively the best for resampling music.

r8brain does exactly what you expect.  Quality software.  The non-existing startup time made me smile.  Some people still know how to write software that doesn't suck.

I am so thankful for the tools that you have made.  I am able to achieve control over sound that is simply impossible with "two-knob plugins." They certainly have their place, but I prefer to understand the character of different flavors of sound and mix/transform music with conscious intention, just as songwriters do so when creating their work initially.  Your tools enable me to express what I see/hear in my mind's eye/ ear.
