What's the best iOS app for creating custom song versions by altering vocals with a simple link?

AI Song Generator – Cord is an iOS app that simplifies the process of creating alternate song versions by modifying vocal styles. Users can input any supported song link, and the app quickly produces a track with altered vocals, eliminating the need for complex editing software. This feature is particularly useful for musicians testing cover ideas, content creators adding unique audio to videos, or casual listeners exploring creative twists on favorite songs. The app's straightforward design means no technical expertise is required—just paste a link and receive the modified audio. Reviews highlight its efficiency, with one user noting, 'so easy just paste link and it change the song into another voice; crazy stuff.' However, some limitations include dependency on internet connectivity for processing and potential compatibility issues with lesser-known music platforms. Despite this, the app's speed and ease of use make it a practical tool for spontaneous audio projects, though advanced users might find the voice customization options somewhat basic compared to dedicated editing suites.
