"Push the tempo" but without pitch correction (based on resampling)

Would be awesome if foobar2000 on Android could do that.
So instead of a "stretch" effect, it would be "simply" based on a resampler (followed by re-interpreting the sample rate as the original value again), and if you make it play faster, it will also play higher, and vice versa, just like it naturally happens with any analog media.

For reference, currently, on desktop, MPV can do this, when configured with:

<< ~/.config/mpv/mpv.conf
audio-pitch-correction=no

and, optionally, to change the speed in logarithmic steps of 1/12 (semitones)

<< ~/.config/mpv/input.conf
[ multiply speed 0.9438743126816935
] multiply speed 1.059463094352953

FB2K on desktop has a DSP plug-in with speed, tempo, and pitch controls ("speed" is what you're talking about).
