Any idea how much $s the fabled cape will cost Russ? Ballpark of course.

Any chance of bypassing the xo reg(s) and using lifepo4 batteries directly (a pin header maybe)? Thanks.

Very impressive that the BBB is keeping up with these high bitrates. This is going to be good.

Much Kudos Miero, you're doing the community a great service.

Hey Russ,

Slightly OT, hope you forgive the intrusion, does the BIII play both .dsf and .dff dsd files or is that something that would be software related from what miero(Mr Wizard) is working at?

Just thought it from something else I have been reading and knowing what format to download or record vinyl in on the Korg unit.

Chuz,

Drew.

I've been able to play stereo DFF files from High Resolution Music DOWNLOAD services .:. FLAC in free TEST BENCH

And DSF is probably "stereo DFF", isn't it?

.dff and .dsf are different container formats.
DSDIFF (.dff) is the Philips standard, and the native container format used with SACD's.
DSF (.dsf) is the Sony standard.

Initially, only the .dff format was supported by MPD and Foobar. But recent versions of both applications now support .dsf as well. In the case of Foobar, it's the "foo_input_sacd" plugin which is relevant.

The difference between container formats only matters to the audio playback application. Once recognised, the playback application should output an identical signal in either case; one which I presume will be understood by Miero's I2S DSD driver.

Did someone want to use LCD cape together with the audio cape?

Because with the current design (audio must be also on top) it will not be possible. Moreover there is some pin conflict because LCD3 seems to use audio data pins for LEDs or something.
