Chri O. Posted April 25, 2023 Share Posted April 25, 2023 (edited) For all of you Falcon owners. I'm just curious if you guys are interested in new Falcon Digital Interface+ Note this is work in progress... Currently what I have developed so far: ADAT out 8ch. SPDIF out 2ch Stereo. USB 2ch to PC (but this is only a side effect for testing). 🙂 Edited April 25, 2023 by Chri O. 8 Quote Link to comment https://forums.atariage.com/topic/350669-falcon-030-fdi-work-in-progress/ Share on other sites More sharing options...

sunaiac Posted May 2, 2023 Share Posted May 2, 2023 Is that an optical out replacement for all audio (including YM) or just a part of it ? Quote Link to comment https://forums.atariage.com/topic/350669-falcon-030-fdi-work-in-progress/#findComment-5248772 Share on other sites More sharing options...
Matej Posted May 3, 2023 Share Posted May 3, 2023 Please keep USB recording to PC too. This can be nice feature to record stuff from AceTracker.

I hear you I wish it was that easy but unfortunately USB has a bit of glitching sound, possible fix means a deep dive into USB descriptors and buffers and low-level code.

What I found fascinating about Atari Falcon audio its the TDM 8 channels protocol, normally digital audio is communicated between chips using I2S protocol. I got to admit the engineers were way ahead of their time. 😲 Edited May 4, 2023 by Chri O. add pic. 1 Quote Link to comment https://forums.atariage.com/topic/350669-falcon-030-fdi-work-in-progress/#findComment-5249480 Share on other sites More sharing options...

Atari74user Posted June 2, 2023 Share Posted June 2, 2023 That sounds like a nice idea in my opinion! So the FDI / SPDIF would be the main part of the unit, and if the user wanted they could add the ADAT In / Out illustrated top left above on your design, not separate PCBs like SPDIF / FDI and ADAT SoundPool built units of old?

Chri O. Posted June 2, 2023 Author Share Posted June 2, 2023 To be honest it's only the input ADAT side that gets expensive as the ADAT output is implemented on the microcontroller. See this: 🙂 Let's just say decoding the ADAT stream is kind of CPU demanded so I am off loading this task to CoolAudio V1402 IC ADAT Optical Audio Data Generator and Encoder DATASHEET PDF:https://mediadl.musictribe.com/download/documents/coolaudio/docs/COOLAUDIO_V1402_DATASHEET.pdf 1 Quote Link to comment https://forums.atariage.com/topic/350669-falcon-030-fdi-work-in-progress/#findComment-5263724 Share on other sites More sharing options...
Chri O. Posted June 2, 2023 Author Share Posted June 2, 2023 Oh I forgot to mention the second port on the PCB is regenerated and clocked ADAT THRU to allow daisy-chaining.

Chri O. Posted June 2, 2023 Author Share Posted June 2, 2023 (edited) Still double checking everything as I was missing 2 decoupling capacitors...

Chri O. Posted June 11, 2023 Author Share Posted June 11, 2023 Just a quick update, this whole ADAT input was a head scratcher so far. Thank God I know how to make good Irish coffee. Just few budge wires and I got this thing going finally. 🙂 1 Quote Link to comment https://forums.atariage.com/topic/350669-falcon-030-fdi-work-in-progress/#findComment-5267822 Share on other sites More sharing options...
