1、What is the advantage of WiFi Speaker over Bluetooth Speaker?

Apparently, there are two advantages: Bandwidth and range.

<1>High bandwidth of Wi-Fi over Bluetooth

Sound quality Bluetooth speakers sound great. But, when playing over Bluetooth, audio data often gets compressed. In that process, some gets lost, meaning your content might not sound as crisp or clear as it might over Wi-Fi. Wi-Fi's higher bandwidth means you can listen in high resolution, up to 24-bit/192kHz.

<2>Range

Of the two, Bluetooth generally has a shorter range, often around 10-20m, and walls and furniture might reduce that further. So, Bluetooth speakers work best when your device is nearby.

Wi-Fi speakers work wherever there’s a good Wi-Fi connection. As long as both your speaker and device are connected to the same network, you’re good to go. That’s handy because it means you can place speakers in any room and control them from wherever you are. If you want to switch rooms—say you’re playing music from your phone in the living room and want to head to the bathroom—you can take your phone with you without the sound cutting out.

2、Advantages of Bluetooth Low Energy for Audio Applications?

There are five advantage point as below.

<1>Extended Battery Life:

One of the most significant advantages in audio devices is their ultra-low power consumption – hearing aids, headphones, and speakers can operate for extended periods on a single charge or battery. Users can enjoy their music or conversation without the constant worry of running out of power.

<2>Low Latency:

Bluetooth Classic normally has a significant associated latency, which is fine for listening to music or having a phone call but causes problems when you’re listening to live content, such as a speech and trying to lip-read, or hearing a mix of acoustic and Bluetooth audio simultaneously. LE Audio allows much lower latency, which enables a whole range of new use cases.

 <3>Improved Audio Quality:

LE Audio included a new audio codec, LC3, which is a significant improvement from the SBC codec which was standard in Bluetooth Classic. Previously, to benefit from lower latency or high-quality audio you were reliant on both devices supporting third party codecs. Listening tests showed that the new codec provides better sound quality even at much lower data rates which means everyone gets these benefits as standard.

 <4>Broadcast Audio:

Everyone is used to the idea of pairing two Bluetooth devices before being able to use them together. LE Audio adds Auracast™, which allows a single transmitter to broadcast to an unlimited number of receivers simultaneously without an unwieldly pairing process. This unlocks a whole new world of audio sharing possibilities.

 <5>Futureproofing:

As technology advances, Bluetooth Low Energy is poised to keep up. Updates and enhancements can be delivered remotely through smartphone apps, ensuring that users have access to the latest features and improvements in their audio devices.
