How to specify samplerate

[ossi]

// GUItool: begin automatically generated code
AudioSynthWaveformSine   sine1;          //xy=257,110
AudioOutputAnalog        dac1;           //xy=440,110
AudioConnection          patchCord1(sine1, dac1);
// GUItool: end automatically generated code

void setup() {
  AudioMemory(12); 
  sine1.frequency(1000);
  sine1.amplitude(1.0);
  }

If I send the sine-data directly to the DAC (see code) where is the samplerate specified?
How can I change the samplerate of AUDIO projects ( at first: no I2S devices used).
What do I have to do if I2S devices (SGTL5000) are involved?

sample rate is fixed 44.1 kHz
you can change it, if really needed, by additional SW
see for example https://github.com/WMXZ-EU/BasicAudioLogger and routines within
