Есть в продаже вот такой Bluetooth модуль Dension Compact BT , вот его характеристики:
specifications for the Bluetooth :
Bluetooth v2.1 + EDR Specification System
Best in Class Bluetooth Radio with +8dBm
Transmit Power and -90dBm Receive Sensitivity
64MIPS Kalimba DSP Co-processor
16-bit Internal Stereo CODEC 95dB SNR for DAC
Low-power 1.5V Operation, 1.8V to 3.6V I/O
Integrated 1.5V and 1.8V Linear Regulators
Integrated Switched-mode Regulator
Integrated Battery Charger
Enhanced Audibility and Noise Cancellation
8 x 8 x 1.2mm, 0.5mm pitch 169-ball ≤FBGA
Support for 802.11 Co-existence
In quality the 2 and 4 and not very different, other functions have been added, the bit rate ( it has 2.1 + EDR ) the EDR can give you 2.1MBit/s, the basic BT is for 781 kbps, but I think in sound related matter, 320kbps is the best where you won't feel quality problems. The output rms is the standard, it should be 750mV. Based on the specifications, the Kalimba supports SBC only, if you ask about the file formats, usually the typical formats that can be played through bluetooth like mp3 wav etc. should work if your phone is capable of handling it.
Какое будет качество звучания с такими характеристиками? На сколько я знаю лучше всего звук будет с кодеком AptX?
Спасибо
