| 1 As of 2021-07-29, our FC Tourmaline firmware has L1_NEW_AEC enabled. As a | |
| 2 result of this change, auw 12 command (sent via fc-tmsh) takes 12 data number | |
| 3 arguments instead of 5, and the full capabilities of the AEC block in the DSP | |
| 4 can be exercised. | |
| 5 | |
| 6 The 3 little one-line files given in this directory (aec-disable, | |
| 7 pirelli-handheld and pirelli-handfree) contain fc-tmsh auw 12 invokations with | |
| 8 different numbers, intended for manual experimentation with our new AEC - run, | |
| 9 for example, sh pirelli-handfree. The 3 AEC configurations are: | |
| 10 | |
| 11 * aec-disable is the default disabled state of the AEC block - the initial state | |
| 12 of your FCDEV3B/Caramel2/etc board if you do nothing. | |
| 13 | |
| 14 * pirelli-handheld is the AEC configuration extracted from Pirelli's firmware, | |
| 15 used in the handheld mode. | |
| 16 | |
| 17 * pirelli-handfree is the AEC configuration extracted from Pirelli's firmware, | |
| 18 used in the hands-free loudspeaker mode. | |
| 19 | |
| 20 Applying pirelli-handfree AEC config to an FCDEV3B setup with the "official" | |
| 21 FreeCalypso HQ loudspeaker and microphone produces noticeable improvement in | |
| 22 voice call quality, as perceived by the person on the far end of the call: the | |
| 23 delayed acoustic echo goes away, and the tester reported that my voice sounded | |
| 24 better too. |
