| Change the frequency of a sample instance in real-time? |

I'm trying to change the frequency of an ALLEGRO_SAMPLE_INSTANCE in real-time (to simulate the Doppler effect). Scanning through the docs, the only way I can see to do this is to create a mixer with the frequency I want, and create a new voice with the same frequency (since they need to match). To do this in real-time, I need to repeatedly create mixer/voice pairs every time I want to update the frequency of the sound. Is there a better way to do this? |

Obviously, that would be bad. You can't re-create your master voice and mixer on every frame. Luckily you don't need to change the frequency of the mixer to change the frequency of the sound. Use al_set_sample_instance_speed to change the frequency of the sample instance in real time.
