I understand that you want echoCancellation and noiseSuppression in most cases, but I would like to be able to turn off all the filter processes for this particular use case. When I set echoCancellation: false in navigator.mediaDevices.getUserMedia, Safari 26 on MacOS produces stereo recording even if I set channelCount: 1. When I set echoCancellation: true, it produces mono recording as expected. How can I get mono recording with echoCancellation: false and channelCount: 1? Thanks!

I can't seem to execute Voiceover command with JXA. The following AppleScript works. tell application "VoiceOver" tell commander to perform command "item chooser" end tell However, the following script in JXA throws a mystery error. vo = Application("VoiceOver") vo.commander.performCommand("item chooser") Error 6: An error occurred. I'd really appreciate any help with this! Thanks so much!
