While being easy to use, Tunesify also strives to perform the highest quality conversions possible. The following features are some of the reasons why Tunesify should be your number one choice if you are at all concerned with audio quality.
Tunesify can convert all popular lossless formats including Free Lossless Audio Codec (FLAC), WavPack, Monkey's Audio, Windows Media Audio Lossless and Real Audio Lossless. These files can be converted to Apple Lossless, which results in no loss of quality. Tunesify can also compress WAV and AIFF files into Apple Lossless with no loss in quality.
Tunesify can convert files containing high-resolution , better than CD-quality audio up to 32-bit and 192 KHz. These can be downconverted into lower quality files that are playable on iPods, iPhones and iPads. With the High-Resolution Audio Add-on, Tunesify can retain their full quality while allowing them to be playable in iTunes. The add-on can be purchased through the Tunesify preferences window.
Audio sounds best when the sample rate is scaled by an even factor. iPhones and other Apple devices will accept a maximum of 48 KHz files. Tunesify can scale 96 KHz and 192 KHz sources to 48 KHz and 88.2 KHz sources to 44.1 KHz. Files that have sample rates below 48 KHz are not scaled at all and the converted files will have the same sample rate as the original.
Tunesify uses Core Audio for encoding AAC, the same encoder as iTunes, and LAME for MP3. These are the best codecs currently available, as demonstrated by blind listening tests for AAC and MP3.
