Re: [fluid-dev] Help with latency using bluetooth headphones

Hi Paul,

I haven't seen any lag with the headphones elsewhere where I try latency tests, and using garageband's musical typing isn't as slow to respond.

As Philippe says, bluetooth headphones have inherent latency issues and are not really suitable for real-time audio. But you say that you only notice the latency when using FluidSynth, so maybe you need to reduce your FluidSynth buffer size. The default is quite high at 16 * 64 samples. Maybe start with the lowest possible buffer size:

fluid_settings_setint(settings, "audio.periods", 2);

fluid_settings_setint(settings, "audio.period-size", 64);

 

And if you get buffer underruns, increase the period-size.

Cheers,
