If improved it has the potential to be great

There is a noticable difference when you first use the app. The music sounds so much more clear, crisp, and even louder. However, there are still small problems with the app that are preventing it from becoming a great app. First of all, it won’t let you adjust the volume at times. In order to change the volume you will need to do it through the bitperfect app instead of itunes, which can get a bit annoying. Secondly, sometimes it won’t change the song playing. It seems as if bitperfect will be playing one song and itunes is playing another–I still haven’t found a way to fix this problem.

Overall this is a solid app with huge potential if the minor problems are fixed. It does enhance sound quality but has a couple bugs that makes it frustrating to use at times. If these problems are fixed then the app is defintely worth the $10.

Mixed blessing

First of all, the price for this program is very reasonable for which the author must be applauded but the effects of the program on my music is mixed.

With CD quality music (16 bit, 44 kHz) enabling Bitperfect had a noticeable effect on the music. Basically it produced a very pleasing atmosphere to the music. Listening to Verdi's Requiem the recording became more alive, and I felt like I was transported from a recording into the concert hall. This was with upsampling enabled, which I believe is beneficial to standard resolution music.

With high resolution files, however, say 24 bit, 192 kHz, it had an opposite effect. The music felt more dead, like the magic was taken out of it. The sound of piano was muddied. I feel that at high resolution there should be no effect on the sound as iTunes is bit perfect on its own, but there was definitely an effect and it was not a positive one.

Which leads me to a mixed conclusion and three stars. As far as up sampling, it is a form of digital processing, and to my mind, is no different from enabling artificial surround sound on an inexpensive receiver. In other words, opposite to the audiophile goal of pure signal path. The psychoacoustic effect on standard resolution files is pleasing, but an artifice. That pleasing effect is probably worth the small fee for this program if most of your music files are CD quality or less.

adds versatility

My iTunes music library contains a variety of lossless formats: 16 bit/44kHz, 24 bit/96kHz, and 24 bit/192kHz, and I prefer to listen without upsampling or downsampling. BitPerfect makes that effortless and switches on the fly 'within' iTunes. For my purposes, this is a solid product at a good price which adds a welcome utility and versatility to iTunes. Of course, you can use it to upsample or downsample too if that’s your thing.
