systems asks also for positioning devices (i.e. GPS) to be turned
ON to make the BLE work. Our app doesn’t use positioning data
but to have it working you probably have to turn ON this
parameter. In some cases the app will try several time to
download the soundbank a nd it won’t complete the download.
In those cases is necessary to allow the use of internal storage
from the Android SETTINGS/CONFIGURATION panel.
Avoid using Bluetooth headphones or speakers with the
re.corder app. The Bluetooth Audio transmission standard
doesn’t allow low latency audio. You will experience long delays
between the production of a note and the audio that you hear!
Use only wired connections to your headset or speaker. Many BT
speakers comes with a standard 3,5mm jack audio input.
TECH: Performance Notes:
While under iOS the performance of the app (which needs
realtime audio generation and processing, and low latency
communication) is quite consistent through the entire range of
Apple devices, Android presents a wider variations due to
different hardware and driver implementations on different
manufacturers and models.
In general, a newer device will perform better, but the optimal
performance with relation to delay, sound quality and
responsiveness of the instrument is not related to the price range
of the device.
