Greetings from Accuwave.
So here it is, the new APM-2.
We've worked a lot with the SSA team in the past year to bring you one of the coolest devices to hit the SPL scene.
The only stand-alone SPL meter compatible with Android, iOS and Windows 10 devices using Bluetooth Low Energy technology. No drivers required, no wires, no initial setup.
In order to use the APM-2 with your device you require one of the following:
iOS 8.4+ starting from Apple iPhone 4s
Android 4.4+ with Bluetooth 4.0 support*
Windows 10 enabled device(Phone, PC, Laptops, Tablets) with Bluetooth 4.0 support**
* Due to different implementations of the Bluetooth drivers in Android, some devices may have unexpected connectivity issues. We are currently working around these issues. Works on all major phone brands.
** App is going online in the following days
Individually tested and calibrated within 0.05 dB. Incredible measurement repeatability due to the 24bit industrial grade ADC, very short analog signal path and low noise design.
Accurate measurements can be achieved from around 95.0 db up to 174.0 db. The high end will be improved in a future firmware update.
2Hz report rate with 1 Hz frequency accuracy.
Stand-alone unit design.
9V Battery powered, with proper battery compartment (sorry for that APM-1 people). This was the only way we could achieve the proper low noise design, DC-DC converters in charging circuits are not friendly.
RGB Logo light. Used as identification color when multiple sensors are connected.
Approximately 10h continuous battery life with good Alkaline batteries.
Auto-off after disconnection.
OTA Firmware updates
Current app features:
Record Basscam videos with live SPL scores. No more wasting video time to film a PC screen. Realtime, Peak and Average scores on video recording.
Connect up to 2 sensors in Basscam, record instant battles.
Measure peak and view realtime scores.
Measure an average score over a time period, countdown and class limit included.
Video render time is device dependent.
Sensor number limitations are platform specific:
Max 5 sensors on Windows and Apple devices.
Max 2 sensors in Android - will improve in future updates
We are constantly working on adding more features, and you will receive app updates seamlessly.
