Could someone from TI please answer this one?

I posted the question below a month ago. It has had 51 views but no replies from TI or anyone else. Could Don Dapkus or someone else please reply to my questions below, even if the answer is no - there are no DACs that can do that. - Thanks.?

Hi, I am using a TLV320DAC32 with an external MCLK input and I want to continuously vary MCLK  on the fly while it its playing audio over a wide range e.g. a 4:1 frequency range to achieve artificial Doppler Shift of the audio signal. The DAC is in I2S Master mode.  I can vary MCLK over a narrow range, but not nearly up by 2 or down by half. I am using an external clock synthesizer chip to generate MCLK.

Does TI make any audio DACs that can do this?.

I just discovered your newer PCM5121/PCM5141 DACS. Could they do this?
