"After September 1st, important functionality in the streaming SDKs will stop working. I don’t own an android device so I can’t test it there. It will then load the audio track and allow pitch manipulation. On iOS, I can do a screen recording of a track, then go into ASD, click import song, and open the video file. Since our app also supports playback and slowing down of streaming Apple Music, many of our users will probably switch from subscribing to Spotify to subscribing to Apple Music. Since no one is looking at this post, it’s fine for now. We believe Spotify will loose thousands of users, so many that the minimal cost Spotify need to spend on maintenance will pay off manifold.
We also have an Android version of our app that uses your Android streaming SDK and it also works very good. Although there are certainly some bugs in the “ios-streaming-sdk”, they are very few and don’t affect our app. We only use "playlist" functions and after fixing a couple of bugs in the "metadata framework" available on github, everything works 100%. Amazing Slow Downer is the ideal tool for an musician, transcriber or dancer wanting to improve their skills. Setup seamless loops by touching the 'Set' buttons during playback. We believe our app gives Spotify many many new subscribers, so many that it would actually pay off for Spotify to maintain the "ios-streaming-sdk". No problem, Amazing Slow Downer handles that as well. All of the best 2023 alternative apps are listed below and regularly updated. Other Amazing Slow Downer like apps are Music Speed Changer Pro 2, Music Dash - Full Mod Fight, GuitarToolkit - tuner, metronome, chords & scales and Mon EcoleDirecte. We have been using those SDKs since they became available. Many users switch from other streaming services such as "Apple Music", Tidal, Amazon Music etc to Spotify just to be able to slow down streaming music in real time. Musicians Toolbox is the best alternative.
It might be that the "ios-streaming-sdk" is more difficult to use for an average developer but that also makes it more powerful. In our case it makes it possible to access the raw audio samples and this way process the sound and then playback the processed audio using our regular audio playback engine. The "ios-streaming-sdk" is a beautifully designed framework that lets an audio developer do practically everything needed. Our particular app (Amazing Slow Downer) lets the user play music more slowly, since a couple of years ago also songs from Spotify. We have been using those SDKs since they became available.
