How it works
The Song Transposer shifts the pitch of your track while leaving its tempo alone, so a song moved down two semitones still runs at exactly the same speed — handy when a song sits just outside a singer's range, or when you want a recording to match the key your band actually plays it in.
Small moves sound the most natural. A semitone or two either way is usually indistinguishable from the original; by five or six you will start to hear the processing, particularly on vocals and cymbals.
Nothing is uploaded. Your file is decoded, transposed, and encoded entirely on your own machine, which is why it works offline and why large files are limited only by your device's memory.
