audio mixer ic

Hello all,

I really don't want to have to use a 8 ch ADC, a DSP and a DAC just to produce a simple 8 to 2 (4 stereo) audio mixer.

I want this project to be as simple as possible. Ideally I want a digitally controlled analog mixer IC. Analog Devices and a few other companies made some very capable ICs for this purpose. Now that digital is fasionable they're all discontinued.

Suggestions please? Who still makes these things?
If there are no suppliers I'm gonig to have to go for a design with many more components, or change my control circuit.

Thanks,
Alan G

Added after 43 minutes:

Looks like I'm going to daisy chain 4 LM1972 2 chanel audio attenuators onto a 3 wire bus and then route the analog outputs to 2 summing amplifiers.

not quite as neat as a single IC solution, but it will have to do.

I'm still open to suggestions for 8+ input parts.

I basically want the smallest, cheapest 8 input, 2 output (4 stereo) digitally controlled mixer for line level signals possible.

This is for a box to sit between DVD players, CD players, etc and an amplifier. Pretty simple once I've chosen the parts. The hardest bit will be on the software side for the uC.

Thanks,
Alan
