Lossless wireless audio: The next generation of BT audio

• Popular codecs used to store music

– MP3, AAC, WMA – lossy formats, which compress audio using algorithms that discard data
– FLAC, WAV, ALAC – lossless formats use compression algorithms that preserve audio data

• Codecs used to transmit music via Bluetooth (limited max bit rate)

– SBC, AAC, aptX, LDAC, LC3 – lossy formats up to 96kHz/24bit
– aptX Lossless – lossless format up to 44.1kHz / 16bit, bit-for-bit exact in CD quality

• LE Audio supporting devices are expected to be exponentially available in 2024/2025
• LC3 codec with superior BT efficiency

– Same audio quality with 50% less bitrate than SBC

• LE Audio enhances BT performance and enables new use cases

– Low-latency gaming mode with parallel voice backchannel
– Phone calls and stereo audio in parallel
– IoT integration, e.g., Babyphone/Doorbell

Your sound, your way with the Smart Control

With a fresh, modern design, Smart Control introduces exciting new features such as Soundcheck to help discover the best EQ preset for your taste and Sound Zones that adapt the sound and settings to your location. The app also provides user accounts to make it easier to enjoy sound your way on all your devices.

Soundcheck

A powerful new feature that lets you identify the perfect EQ preset. A fast and simple, three-stage guided process lets you listen to and select your preferred tuning from several options and shows you which preset is the best match for you.

Sound Zones

Automatically switch to your preferred settings for specific locations. When at home, in the office, or even in the streets, the location data will automatically adjust the EQ setting, switch ANC on/off, or change Transparency Mode when entering these areas.

Sound Personalization

By using advanced technology, this feature can create individual sound profiles for the
users' headphones. By the use of a simple and engaging listening test, the technology will create a profile perfectly fitted to the user's sense of hearing.
