// to the last frame in the file and will do an implicit Pause() there.

// be played back.

// Runs the current playback session forward at a higher speed.
// TODO allow different fast forward speeds???

bool Pause(void);
// Pauses the current recording or playback session, or resumes a paused
// session.
// Returns true if there is actually a recording or playback session
// active that was paused/resumed.
void Stop(void);
// Stops the current recording or playback session.
int Frame(void);
// Returns the number of the current frame in the current recording or
// playback session, which can be used to start playback at a given position.
// The number returned is the actual number of frames counted from the
// beginning of the current file.
// The very first frame has the number 1.
