Technical field

The invention belongs to Audiotechnica field more particularly to a kind of balance parameters matching process based on interpolation processing, dress It sets, terminal device and storage medium.

Background technique

Speaker is the terminal of entire sound system, and effect is audio electric energy to be converted into corresponding sound energy, and its spoke It is mapped to space to go, it is the extremely important component part of sound system, is responsible for the ear that electric signal is transformed into acoustical signal for people Piece directly listening to for task.But in some cases, for example performance is live, may not provide the speaker of speaker or offer Because using the time longer, equipment is weathered, and tone color quality complies with one's wishes not to the utmost, and speaker volume is heavy, if performance all carries every time It is outgoing, it is also inconvenient for musician.In addition, a good speaker is expensive, for needing various other speaker sounds For the people of color, more speaker costs of purchase be undoubtedly also it is very high, the speaker moulds of various speaker tone colors can be simulated at this time by selecting It proposes standby, is a wise selection for musicians.

And the tone color of speaker is ever-changing, is influenced by parameters such as equilibrium, gain, overload, reverberation, volumes, it is existing Speaker analog machine in the tone color of simulated target speaker, need first the tone color by target speaker be adjusted to a satisfied tone color again into The replica samples of row tone color, simulating the tone color come at this time is the speaker tone color under this group of special parameter, if adjusting one of them Parameter then needs to carry out resampling.And in the numerous parameters for influencing speaker tone color, balance parameters play the adjusting of tone color Critical effect, existing speaker analog machine are needed when acquiring the tone color of different balance parameters for different equilibriums Parameter is frequently sampled, and cannot pass through the phase on speaker analog machine when the balance parameters variation on target speaker The adjusting balance parameters answered, to realize dynamic synchronization rock noise color change.
