No nyt alkaa sitten Androidille tai ainakin Samsungin Android-laitteille tulla kunnon musasoftaa kun saivat aikaiseksi tuo Samsung Professional Audio SDK:n:
http://www.ikmultimedia.com/product … ndroid/index.php?pp=at-android-info http://www.synthtopia.com/content/2 … ime-audiomidi-solution-for-android/ Kovin vanhoille laitteille ei varmaan tukea tule, S5 taitaa olla eka tuettu puhelinmalli, ja sitten on noita tabletteja.
Latenssi ei taida olla ihan tarkaan speksattu vaan eri laitteiden välillä on eroa:
"Q:Is it possible to share some detailed breakdown of the latency numbers, e.g. touch input latency, audio output latency, audio buffer latency (which should be 5.33ms for 256-frame buffers at 48kHz), JACK system latency to connect multiple apps together, and application-dependent latency?
A: Professional Audio API supports 240, 480 and 960 frame sizes at 48 kHz sample rate. When the case of using: Galaxy Note 3 Samsung Exynos 5 Octa (Exynos 5420), 48khZ, 240-frame touch input latency : 56.84ms = Touch device (average 32.34ms) + UI framework (average 12ms) + Audio-Front-End-delay(2.5ms) + buffer latency (240-frame, 2 buffers = 10ms) audio output latency (without touch) : 12.5ms = AFE (2.5ms) + buffer latency (10ms) audio input to output latency : 12.5ms = AFE (2.5ms) + buffer latency (10ms)
** DEPENDING ON CHIP SET ARCHITECTURE LESS THAN 10ms ADDITIONAL LATENCY MIGHT BE REQUIRED"
Eli joillain piirisarjoilla on jotain max. 10 ms extralatenssia, ei kuulosta hyvältä.
