Audio Sub-Board #9
Description
Audio Sub-Board
This segment of the project is mandatory for having a complete single run capture chain for VHS/Betamax formats like SMPTE-C/2" Quad/Umatic only have linear audio capture so they are stuck in automation limbo without the addition of a sub-board or version with audio inputs.
This issue tracks the ideas & solutions for audio.
Requirements
2-4 Channels with balenced/unbalenced support
For a dedicated device these connectors are suitable:
Quad TRS / Quad XLR TRS Combo - Nutrik Connectors
For a PC add-in card module style system however 6.35mm jacks are the best way to go.
Perposed Solutions
Pi Pico + Clock Source
Using the current clockgen board as a foundation this would be easy to script into current CLI capture.
Namazso made a more slim down version here which will prob be the quickest solution to capture scripted using the MISRC clock source.
Custom Board
Using an PCM1840
Using an PCM4204
