Pitch-shifting and Speed changing of a track, how can this be achieved? (Djay 2 app does this somehow)

[432player]

Hi there, the existing app called Djay 2 for Android declares the following:

Spotify integration: mix and remix millions of tracks instantly • Music library integration (mix all files and create your own remix, no access to Google Play Music) • Match: intelligent song recommendation engine powered by The Echo Nest. Create a remix of your favorite tracks with intelligent song recommendations. Music selection and mixing has never been easier and more fun. • Audio FX: Flanger, Phaser, Echo, Gate, Bit Crusher (create your own sound) • Mixer, Tempo, Pitch-Bend, Filter and EQ controls ... We have a music player that relies on pitch-shifting and track speed control, how can we succeed in doing this as well?

Blessings,

Hi @432player I'm afraid that this functionality is provided by our deprecated streaming-sdk.

Unfortunately, we can't offer any functionality that modifies the original audio of the tracks in our catalogue.

Hi @mdelolmo so it is a legal problem not to change the original tracks? When it comes to audio books (that are often albums/compilations) a different playback speed could be interesting, but I get it if it's not allowed.

Hi @tobika I don't have much detailed information, but essentially yes, it's a licensing issue.

Wait, really? So apps like "Amazing Slow Downer" (https://youtu.be/qoI11hEww5k?t=54) are no longer going to be able to actually slow the pitch down anymore?
