Comparison and differences between Classic Audio and LE Audio in Bluetooth audio:
- Low Energy Consumption:
Classic Audio: Bluetooth Classic audio is known for its relatively higher power consumption, which may not be ideal for devices with limited battery life, such as headphones or IoT devices.
LE Audio: One of the primary goals of LE Audio is to reduce power consumption, making it more suitable for low-power devices and enhancing battery life.
- Improved Audio Quality:
Classic Audio: While Bluetooth Classic audio supports various audio codecs, the quality may vary, and some users may experience issues like latency and compression artifacts.
LE Audio: LE Audio introduces the LC3 (Low Complexity Communication Codec) codec, which is designed to provide better audio quality compared to previous codecs used in Bluetooth audio.
Classic Audio: Typically, Bluetooth Classic audio supports single-streaming, meaning one audio source connects to one audio sink at a time.
LE Audio: LE Audio supports multi-streaming, allowing one audio source to connect to multiple audio sinks simultaneously. This feature is beneficial for scenarios like audio sharing or connecting to multiple headphones from a single source device.
Classic Audio: Bluetooth Classic audio is widely adopted and supported by a vast array of devices, including smartphones, speakers, headphones, and more.
LE Audio: As LE Audio is a newer standard, its adoption may take time, and device compatibility may be limited initially. However, as the technology becomes more widespread, more devices are expected to support LE Audio.
- Backward Compatibility:
Classic Audio: Devices with Bluetooth Classic support may not be directly compatible with LE Audio devices, and vice versa.
LE Audio: Some efforts have been made to ensure backward compatibility, allowing LE Audio devices to work with Classic Audio devices, but it may depend on the specific implementations.
