With the continuous development of the digital era, digital technology is more and more closely combined with various fields, and the integration and development of digital music technology in vocal performance has also received wider attention. This study analyzes the hierarchical relationship of digital music in depth, explores the effect relationship of digital music technology in combination with vocal recording collection, and further studies the interaction effect of intervening digital music technology in vocal performance from the perspective of interaction relationship. In the actual vocal performance, the peaks of the left and right channels of the music signals of the intervening digital music technology were around ±0.30 and 0.10, respectively, and the volume of the left channel was larger than that of the right channel. In all aspects, the effect of vocal performance on music acquisition is better with digital music technology. Meanwhile, the highest ratio of audience silence in the interactive impact of vocal performance intervening digital music technology was reduced by 10% compared with the traditional vocal performance, which proved that the vocal performance based on digital music technology has a better interactive effect and provided a solid and reliable basis for the development of the integration of digital music technology and vocal performance.
