It goes without saying that with its skilled team of RF engineers, LM also makes excellent audio products.

What doesn’t go without saying, however, is that we also utilise a variety of silicon vendors and technologies to offer our customers the best solution possible, anywhere from a low-bitrate mono audio over Bluetooth® low energy, to aptX® high-quality stereo audio over Bluetooth® v2.1, v4.x  + EDR.

LM’s hardware origins spur from its Bluetooth® adapters that utilise Cambridge Silicon Radio (CSR) silicon. CSR is sole the inventor of the renowned aptX® high-quality Bluetooth® audio streaming technology that is found within almost all high-end smartphones and Bluetooth® enabled speakers, headphones and earphones on the market today. LM offers a variety of audio modules within its line-up based around CSR silicon and its associated leading-edge Bluetooth® audio technologies.

Our LM745 Bluetooth® Audio Module features an on-board DSP for intensive audio codec processing, including support for aptX®and a high-quality 95dB SNR DAC.


In the near future, LM will be expanding its audio range to include products from Broadcom, specialising in high-quality and lossless HD audio streaming over WiFi, including multichannel 5.1. Broadcom have a proven track record for working closely with large corporations to ensure the best possible support for their propriety profiles, such as Apple AirPlay™ and have chosen to extend this same level of support to LM Technologies, who are also a member of the Apple MFi program.
