haddy Posted January 27, 2021 Share Posted January 27, 2021 I am currently unable to download any new Android apps as I await a new phone so I cannot confirm if Tempo is supported. Is Tempo supported? Going by the app screenshots, it doesn't appear so: https://play.google.com/store/apps/details?id=com.maxmpz.equalizer&hl=en_GB&gl=US It would be AMAZING to be able to alter the Tempo (and later Pitch) of my focused YouTube Music songs. What are the technical possibilities or limitations of this? Quote Link to comment Share on other sites More sharing options...
andrewilley Posted January 27, 2021 Share Posted January 27, 2021 No, I can't see how Tempo could be implemented in an EQ (only) app? The speed of audio playback has to be governed by the provided audio from the playing app, the PA EQ can only adjust the sound it is given.

YouTube's video player (youtube.com and phone app) gives the user option for 'Playback speed' much like 'tempo' in Poweramp. Is this because the video being streamed is cache locally to the users PC/phone or not? Surely Temp is possible with Poweramp EQ app. Right?

andrewilley Posted January 27, 2021 Share Posted January 27, 2021 Pitch would be possible in an EQ app, but tempo (actually changing the playback speed) would not. Andre Quote Link to comment Share on other sites More sharing options...
haddy Posted January 27, 2021 Author Share Posted January 27, 2021 Thanks for your support. What is the technical limitations for changing the playback speed in the EQ app? I wonder how Youtube's video player allows for changing playback speed for so many users around the world? Quote Link to comment Share on other sites More sharing options...
andrewilley Posted January 27, 2021 Share Posted January 27, 2021 Given that the audio playback data is suppled from the source app (e.g. YouTube or Spotify) at a fixed real-time rate, how would you propose Poweramp plays it back any faster or slower? The only option would be to break sync from the player source and buffer the whole real-time song in memory first, and then (for example) start double-speed playback after about half of the track has been received - meaning that a four-minute song would be silent for two minutes and then start its double-speed playback for the next two minutes. Not really feasible or desirable. Andre Quote Link to comment Share on other sites More sharing options...
