Sonoma Low Latency Solution for AndroidFor Android users, this new solution from Sonoma could make creating music on your phone or tablet a far more responsive experience. Further information from Sonoma follows. Press Release: Sonoma Wire Works, makers of the FourTrack™ iOS multitrack recording app, the AudioCopy™/AudioPaste™ SDK, and the GuitarJack™ audio interface, has developed a low latency audio (LLA) solution for Android™ devices.

Fantastic! 26-Jan-13 05:19 PM Gaz Said... Now things are about to get interesting... Low latency audio in Android 4 (Ice Cream Sandwich) This is a short video I made showing a song I produced using my ASUS Eee Pad Transformer TF101 dual booting to Linux, including links in the description on how to: I don't know if this is exactly relevant, because it's not Android OS BUT it is on Android intentioned hardware.

So if anyone has the hardware and is looking to experiment (root and flash at your own risk, though not too risky or complicated if you follow the instructions in the xda forums completely), have at it! This opens you up to having a mobile sequencer with soundfont support and tablet keyboard working as a midi controller (LMMS), Hydrogen drum sampler (latency issues, but good enough to export to wav or ogg once you have a pattern down), and Audacity for (very) basic sound recording and fairly decent editing. Everything used in this recording (except the tablet) is free and open source. Hope someone finds this useful! Oh, and that's not even mentioning Open Office and GIMP running on this system =)[/url]

Android, High-Performance Audio in 4.1, and What it Means – Plus libpd Goodness, Today. It’s called “Jelly Bean.” But a 4.1 version of Android might also be called, at last, a version of Android musicians will find tasty. (Those last versions were a bit more of the disgusting variety from Bertie Bott’s Every Flavor Beans; this is a bit more Jelly Belly.) Photo (CC-BY-SA) Hermann Kaser. Android devices may, at last, get the kind of sound performance that makes music and audio apps satisfying to use. An update on the Android audio latency issue. With the advent of newer versions of Android (4.1, 4.2) and newer devices, the topic of latency has come a bit more into the mainstream of system development.

Newer APIs in the Android SDK are providing means to enquire devices about low-latency parameters (buffer sizes and sampling rates). But how does that translate in practical terms to latency reduction? My tests with Csound Well, I got hold of a Google Nexus 7 tab this week and went about measuring it. Using the latest Csound, whose OpenSL IO code is (I expect) optimal, I first measured touch-to-sound, and then round-trip latency. Results were as follows: best touch-to-sound latency: ~120msbest round-trip latency: ~105ms The parameters for Csound were -B1024 and -b128, which means, in this particular case, circular buffer and audio buffer sizes of 1024 and 128 frames, respectively.

Although the round-trip figure is far away from low-latency, it is actually becoming more usable. Other reports Conclusions 1. 2. 3. Latency_and_latency_correction [Audio Evolution Mobile Manual] Latency, what is it?

Latency comes in different flavours, but what we will talk about here is the time delay between succesively recorded tracks. When you have an audio sample on the first track and you record a second track playing along the first one, you want these two tracks to be perfectly aligned. On desktop systems, this problem is taken care of by a good audio system that has facilities like synchronised start of playback and recording, very accurate reporting of play head position and more.

Examples of these are ASIO (Windows), Core Audio (OSX) and ALSA (Linux). Also, our own USB audio system that is available since 1.8.0 has relatively accurate positioning information. Android however, was made primarily to make phone calls and play your mp3's. NAMM 2013: Sonoma Wire Works announces Android low latency audio solution.

NAMM 2013: We're not sure exactly what this means, but Sonoma Wire Works has thrown a potential lifeline to Android music makers by announcing a low latency audio solution (LLA) for the platform.

Available for license to device manufacturers, this promises to bring latency down from the typical 100 to 250 milliseconds to a much more palatable 20 milliseconds. Many questions remain - which versions of Android and which handsets will this work with, for example - but at least users of Google's mobile OS now have some hope on the horizon.
