Latency: Bluetooth LE Audio vs Classic Bluetooth

Classic Bluetooth Latency Challenges

Classic Bluetooth often struggles with latency issues that can disrupt your audio experience. Typical latency measurements for Classic Bluetooth in audio transmission hover around 100ms. This delay can lead to noticeable lag, especially in activities like gaming or watching videos. When you play a game, even a slight delay can affect your performance. Similarly, during video calls, you may find that the audio does not sync well with the video, making conversations awkward.

Benefits of Bluetooth LE Audio Latency

In contrast, Bluetooth LE Audio significantly improves latency, achieving times between 20ms to 30ms. Some benchmarks even show Bluetooth Low Energy (BLE) achieving latency as low as 6ms. This reduction in latency allows for much more responsive device communication.

Lower latency in Bluetooth LE Audio leads to a more synchronized audio experience. This synchronization is crucial in gaming, where timing impacts performance. In video calls, lower latency aligns audio with video, enhancing communication and engagement. The Dimensity 9400 supports low latency audio streaming, which is essential for immersive experiences in gaming and video calls. You can enjoy longer listening times due to lower power consumption, making Bluetooth LE Audio a practical choice for daily use.

With these advancements, Bluetooth LE Audio not only enhances your listening experience but also opens up new possibilities for applications that require real-time audio feedback.

The LC3 Codec and Audio Quality

LC3 vs SBC: Key Differences

The LC3 codec offers significant advantages over the SBC codec, especially in terms of audio quality and efficiency. Here’s a comparison of their key features:

Aspect	LC3 Codec	SBC Codec
Audio Quality	Significantly improved, better even at low bit rates	Default codec with lower audio quality at similar bit rates
Compression Efficiency	Provides acceptable audio quality at lower bitrates, enabling lower energy consumption	Requires higher bitrates for comparable quality, leading to higher energy use
Battery Life Impact	Enables longer battery life due to lower bitrate and energy use	Higher energy consumption reduces battery life
Bitrate Range	Scales between 345 kbps to 160 kbps with 16-bit depth	Typically higher bitrates needed for quality audio

This table illustrates how LC3 maintains high-quality audio even at lower bitrates. Extensive listening tests confirm that LC3 delivers improved audio quality over SBC, even when operating at half the bitrate. This efficiency allows you to enjoy better sound without draining your device’s battery.

Impact on Power Consumption

The LC3 codec excels in power efficiency. It allows for high-quality audio transmission at lower bit rates, which leads to reduced energy usage. This feature is crucial for wireless audio devices, as it directly correlates to extended battery life.

The LC3 codec enables developers to create devices that can either extend battery life or maintain the same battery life while improving audio quality.
Listening tests indicate that LC3 can provide better audio quality than the SBC codec at a 50% lower bitrate, which directly contributes to lower power consumption.

By using LC3, you can enjoy high-quality audio without worrying about frequent recharges. This low power consumption makes Bluetooth Low Energy (BLE) devices more practical for everyday use, enhancing your overall listening experience.
