New audio technology will cause waves in karaoke apps in China

    The main KTV apps in China include Quanmin KGe, Sing Bar, and Teana KGe. Using an example, let‘s take a look at the large number of karaoke app users in China. The Sing Bar app alone has been downloaded 300 million times, with 70 million active users (more than the total population in the UK) and 4.5 to 5 million users online simultaneously. This is just an application. Tencent‘s "National K Song" is more popular. As of July 2016, Quanmin K-Song ranked eighth in China‘s app stores.

    In addition, users attach great importance to these KTVAPPs. Users can practice over and over again in practice mode until the final recording is completed, and share their songs with others through social network features. They can even record some songs or videos for others to perform a duet afterwards, and everyone can sing the same song no matter where they are.

    For Android users, the performance of the KTV app is not ideal because they cannot hear themselves singing while wearing headphones, which is the default mode of the KTV app. The 10 millisecond high latency on Android means that app providers cannot mix microphone signals onto the headphone path like on iOS, or at least do not produce any delay effects that affect the user experience. Removing headphones and using speakers can also be problematic as it produces "echoes". When the music played by the speaker is recorded by the phone‘s microphone and added to the original track, it will produce echoes, and the recorded audio effect will be severely distorted.
