Centshift

Your music. Finely tuned. Centshift retunes existing recordings to your chosen reference, from 380 to 480 Hz. Switch between 432 and 440 Hz or save your own tuning favourites. Tempo and duration stay the same. Care you can hear The audio engine processes stereo channels together and has been tested with different genres and vocals. Centshift checks the actual pitch shift and file integrity. A clear traffic light shows whether the conversion is confirmed or remains inconclusive. Larger changes may introduce audible artefacts; use the preview to judge the result. Compare with confidence Listen to the original and retuned preview side by side. Automatic analysis estimates the source tuning. If you know your recording's reference, you can set it yourself. One track or a whole collection Open multiple files, process them in batches, and choose the output folder and filename suffix. Your originals stay unchanged. Favourites are saved on the device you use. Private on your device Analysis and retuning happen locally. The shared free-export counter stores only technical export identifiers in your private iCloud database at Apple. Your music is not uploaded for this purpose. Take your time trying it The built-in music example can be previewed and compared, but cannot be exported. The free preview includes a spoken “Centshift Demo” notice after 45 seconds of actual playback. Five exports of your own music are free in total per iCloud account.
