| 1 spkr0 is the new (as of 2021-10) audio mode config for FCDEV3B | |
| 2 loudspeaker+microphone voice call kit. The other two configs are historical | |
| 3 and should no longer be used: | |
| 4 | |
| 5 spkrmax config was my (Mother Mychaela's) concoction at the time when I tried | |
| 6 to use tiny cellphone-sized speakers, which were too quiet in the absence of | |
| 7 special mechanics and acoustics. It needs to be noted that setting a positive | |
| 8 speaker "calibration" gain in the Iota ABB with the volume control set to max | |
| 9 and with the waveform at full scale produces clipping instead of more Vpp | |
| 10 output, hence this approach is not really a solution. | |
| 11 | |
| 12 mcsi config was an early method of entering MCSI digital voice mode, but this | |
| 13 method should no longer be used, as it is broken - use AT@VSEL=1 instead. |
