Though the film Manu had failed at the box office it has been lauded for its artistic work in every department. The makers of the film had not compromised in a single department and had delivered a top-notch output. The film's sound design is also one among them where the music director had used the Shepard Tone which was used in the films like Dark Knight, Interstellar and Dunkirk, where the sound feels like it is constantly increasing the intensity but it will be in a straight line. The music department had done a fantastic job that our eardrums can experience even a minute sound from the frame. The makers have released the OST's (Original Sound Track) from the film which are haunting the audience. Check them out.
