improve the performance of audio echo

[alexd555]

Hi,
Could you explain how to use this library ?
How much better can it improve the latency than OpenSL ES ?

I have this implementation of audio echo with hpf filter and I want to improve performance and latency.
Maybe, do I need to add threads ?

Could you help ?

Thanks,
Alex

Oboe is a wrapper for the AAudio and OpenSL ES APIs. It will use AAudio on devices running Android version 26+ for best performance.

Could you be more specific about your problem, are you getting audio glitches? Are you trying to improve computational throughout?

I want to improve latency.
What do you mean "glitches" ? Give me example please.

A glitch is caused when you cannot supply audio data within the audio callback deadline. https://youtu.be/C0BPXZIvG-Q?t=15m52s

You cannot improve latency. All you can do is use the Oboe library and follow the best practices for setting up an audio stream (sharing mode: exclusive, performance mode: low latency, buffer size: 2 bursts). This will give you optimal audio latency on the widest range of devices.
