[Reads MAS spec] You're certainly right about the mixing (assuming that the mic is attached to the mic input and amplifier in the MAS, which seems likely; I'll admit to not being good enough at reading schematics yet to grok that from the schematics you drew)... ... and you're correct, I missed the bit that implies that multiple applications may be enabled at once (although I imagine it draws more power when you do that). But I'm still not sure where the microphone input gets reported, except in the peak meters. Was that what you meant by `monitoring'? I'll try turning both encoding and decoding on, and see how it goes. -- #ifdef USE_ISPTS_FLAG } else { /* else pty, not pts */ #endifReceived on 2003-03-15 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
