Recording Chord MScaler Output

The link I provided above gives the basics of what needs to be done... A perfect or infinite sinc function does the heavy lifting... You could start with a OpenSource program that already does audio format conversion and filtering like SoX... Add a little hacking sinc function and there you go... I wouldn’t be surprised if someone hasn’t already done this...

Again, HQPlayer can do the 1MTaps and filters that approximates what an MScaler does...

The Qutest does a WTA1 16FS filter 49,152 taps and upsamples internally so no need for you to... Actually, the designer, Rob Watts, suggests not to upsample for any of the Chord DACs...

Additionally..  Rob Watts said: "For Hugo 2/Qutest the signal path is:

1FS to 8FS input > 16FS WTA1 filter (49,152 taps) > 256FS WTA 2 filter > 3rd order 2048 FS filter > pulse array noise shaper at 104 MHz > analogue

When an M scaler is connected, the WTA1 filter is not used, and it is passed through to the 256 FS WTA 2 filter."

I suspect that anything that approximates an MScaler in software would not splice into the above internal signal chain the way the MScaler does and might not sound the same...

akwilson501,
I love your idea, and it seems technically possible.  And if you did it once, why not a second or third time, each time using that upscaled file as your new starting point.  But maybe the files would be massive and use up too much memory.   You should check the M-Scaler page on Head-Fi...   Rob Watts responds to inquiries there...
