Truly Effective Upsampler

I can hear the skepticism already: "Effectively upsample my CD collection? Really??" Ordinarily, it would be true merely increasing the bit depth and sampling rate alone does nothing to improve sound quality. It does nothing but add a bunch of trailing zeros. However, using the ffmpeg aexciter audio filter, this front end program fills in those zeros with actual numbers. The aexciter filter, like other harmonic exciter hardware and software creates additional harmonics and overtones. (See the Wiki tab for more details.)

This front end program opens up the sound, and makes it more transparent...as one expects to hear in typical Hi-Res digital, and/or analog recordings. Comparing an iTunes download with the equivalent Hi-Res download, the aexciter filter was set up listening primarily to the reverb characteristics. The resulting output is virtually indistinguishable from the equivalent Hi-Res download. Processed Amazon MP3 older rock albums closely resemble the original vinyl.
