A Mixing system automatic combines the skills of all the experts involved in music and sound production. Artists, engineers, producers, managers, executives, manufacturers, and marketing strategists all come together to turn creativity into a product that can reach the world.
Auto mixers are capable of reducing feedback, minimizing extraneous noise and improving sound quality by preventing comb filtering. They can also be adjusted to different levels for different talkers, making them useful in applications with a wide range of skill levels.

The world of music and sound production is a complex and diverse realm. It involves artists, engineers, producers, managers, executives, manufacturers, lawyers, media, marketing strategists, and more – all combining their expertise to achieve a single end product that can be enjoyed by the listener.
Despite the many advances made in technology, audio mixing remains a highly manual process that requires a trained professional to produce quality sound. That said, automatic microphone mixing is a tremendous problem-solving tool that eliminates common problems such as insufficient gain before feedback or muddy speech quality for large-room applications such as conferences, houses of worship, and government facilities.
This research focuses on developing an automatic mixing system capable of producing mixes that are comparable to those prepared by a professional human mix engineer. This will be achieved through subjective comparison and error distance measurements between a target mixture style and the automatically mixed input tracks.
Feedback, that annoying squealing or howling sound that comes through the PA, is a real issue for performers and engineers. It can ruin a show and can be distracting for the musicians on stage.
Feedback is caused when the signal enters a microphone, is sent to a sound system and amplified through speakers. When the amount of amplification is higher than what is necessary to reach the desired sound, feedback will occur.
A number of factors can cause feedback problems. Placing the mic too close to the speaker, using a microphone that is not directional or turning up the microphone level too high can all increase the chance of feedback occurring.
When a problem is detected, it’s important to locate the feedback frequency and apply equalization to reduce its presence. Typically, feedback frequencies are in the 250 to 500 Hz range, but can also be above 1 kHz.
