4TUNE automatically detects the pitch of a vocal performance with low-latency, real-time pitch tracking, and rates the pitch deviation within a pre-defined scoring system.
The 4TUNE algorithm offers an easy-to-use interface, and requires only the karaoke backing track and some information regarding the vocal’s melody. The 4TUNE SDK’s lightweight architecture is designed specifically for karaoke platforms, making it suitable for mobile devices.
Thanks to the SDK, implementing the 4TUNE algorithm in karaoke applications and other tools is a simple process. Developers can integrate our advanced signal processing into their own tools with even a basic understanding of the deeper signal processing.
