You may be seeing variations in CPU clock speed. That can lead to some puzzling benchmark results. I gave more detail in my answer on the Android list. By the way, one way to prevent overly aggressive optimization is to generate a check some of the results of your benchmark and then print that

Hallo again! Thanks for all the suggestions and for already starting the discussion - I would have many questions as well ;) Just as a quick summary, the two main suggestions were the JUCE forum: https://forum.juce.com/c/android And the andraudio group:

Re: [music-dsp] Android related audio group / mailing list?

Hi Nuno, Thanks for this opportunity to allow me to help you understand audio latency on Android better. Contributions to total round-trip audio latency on Android are best thought as stemming from two parts. A) Android service space (AudioFlinger etc) ← developers and middleware cannot affect

Hello Nunos, I just joined https://groups.google.com/forum/#!forum/andraudio I think that is a good place for discussion. If you repost your questions there then I will try to answer them. Phil Burk On Wed, May 25, 2016 at 6:15 AM, Nuno Santos wrote: > I have been

Patrick, Now that I had the chance of using Superpowered all I can say is that it doesn’t make miracles. It will not provide lower latency than OpenSL already gives. Android latency problem is much OS and device dependent. Looking forward to understand what is new and if it will bring any

Speaking of Android, we just released a fully configuarable and performant USB Audio and MIDI library for Android. It’s the Android equivalent of iOS Core Audio and Core MIDI for USB devices. http://superpowered.com/android-usb-audio-android-midi The Superpowered USB Audio and MIDI SDK provides

I have been testing DRC in 2 different Android devices: Nexus 9 (48000/128 buffer size) phone, Bq Aquaris M5 phone (48000/912) buffer size Nexus 9 is a beast. I was able to run DRC with full polyphony (8 voices) without any kind of glitch. The fake touches hack was essential to make this

Hi, I do not see drives in the andraudio group since he migrated to [1] Some years ago I tried see how some of my codes works in android, I wrote effects to work in real-time (automatic pitch correction, time stretch, pitch shifters in time domain and frequency domain) and I get a lot of

Re: [music-dsp] Android related audio group / mailing list?

At JUCE / ROLI we've been working with Google for over a year to optimize audio latency, throttle, etc for cross platform apps. Our app is featured also in the Youtube video from Google IO, and it runs on some devices with performances comparable to iOS. Whether you are using JUCE or not,
