Hi,

Can the biquad parameters be updated on the fly without any adverse artifacts in audio?

Thanks in advance,

For mono use case, can the 7 biquads of each channel be combined to yield 14 biquads?

Hi Goldy,

1. The device support coefficients on-the-fly change without audible noise;

2. No, in Mono use case, the 7 biquads can't be serialized to be 14 biquads along the signal chain.

BTW, TAS5707 is quite an old device, would you like to take a look at the latest generation device TAS5805? It provides better performance and lower cost.

Thanks!

Regards,

Sam
