I have audio files playing on my Audio FX Mini Sound Board and I would like to control the playback speed, specifically the tempo, without changing the pitch/frequency. What I need is a physical knob that will act as playback tempo controller.
On the product page for this sound board (https://www.adafruit.com/product/2341) it says, "Control over UART (9600 Baud) via any microcontroller, we have an Arduino Library for basic control over playback and volume."
Does that statement indicate capability to do what I need? And where can I find the mentioned Arduino library?

Re: Playback control with Adafruit Audio FX Mini Sound Board
Our library for the Fx board does not support changes to the playback speed. I'm not sure if that is possible with the VS1000 chip.

The VS1053 used on the MusicMaker boards is a more powerful and programmable chip.

The MusicMaker library exposes only a subset of its functionality. The VLSI forums would be the best source of information about more advanced signal processing capabilities.
