Description

Technical Field

[0001] The utility model relates to the technical field of musical toys, and more specifically to a sound mixing popular science toy. Background Art

[0002] Mixing is a step in music production that combines sounds from multiple sources into a stereo or mono track. These mixed sound signals may come from different instruments, vocals or orchestral music, recorded from live performances or studio recordings. During the mixing process, the mixer will adjust the frequency, dynamics, sound quality, positioning, reverberation and sound field of each original signal separately to optimize each track, and then superimpose them on the final product. This processing method can produce a perfect effect with distinct layers that ordinary listeners cannot hear in live recordings.

[0003] In the past, the common equipment used for mixing was mainly synthesizers, sound processors and mixing consoles. Now, with the advancement of computer technology, it has become popular to use music production software for mixing. Complex mixing tasks can be completed using only a computer and mixing software.
