Playing Audio and Video in Delphi 10.1

I've been using D7 and DSPack supplemented with calls to DirectShow for
many years.

This has been quite powerful and allowed me to use various filters.

Now I need to find a solution that works with D10.1 on Windows, OSX,
Android and iOS.

Most important is I need to be able to change the pitch and speed of
playback independently and also be able to playback more than one file
at the same time.

What options are available?

Changing pitch and speed in audio is available with BASS:

Thanks for the suggestion.

Over AUD$5100 is considerably more than I can afford.

Are you aware of the free, open source, SoX library? There is a multi-platform Delphi example project here:

Disclaimer: I have not used this myself.

No, I was not. On initial read it sounds like it's not real-time, but
I'll look into it. I also need to access the audio streams from video
files, not just audio files.

Thanks for your reply.
