[FEATURE REQUEST] I2S Speaker Output about esp32-cam_mjpeg2sd HOT 18 OPEN

I'll start with browser on mic enabled pc to send stream to esp32

telemetry.cpp intended as a user edit

from esp32-cam_mjpeg2sd.

could you give a more specific use case for the speaker.

from esp32-cam_mjpeg2sd.

Some Ideas

1. Doorbell camera. Push button and plays a selectable doorbell chime sound.
2. Doorbell camera with 2 way audio so you can talk to the person at the door
3. Intercom so one mjpeg2sd could talk to another in a different room
4. Pet camera so when your away you can see and talk to your pets
5. Application voice feedback like Wifi Connected, camera recording etc.
6. Surveillance camera with human voice deterrent pre recorded like "Recording Started"
7. Make car/truck/tank sounds like a horn or rev engine through remote control
8. Robot with vision, hearing and a voice in 1 perfect package

I know a few ideas could be classed as 1 but trying to give user cases. To be able to play sounds from sd card or stream to device, would be nice but both would be great. I know it could be difficult to implement. Think this would be a great next step into this project.
Using a i2s MAX98357A amp board. Would only need 1 extra pin if using with i2s mic too

Off Topic.
I am starting to get my head around your code and started to add a oled screen, hlk-ld2410 radar, also updated telemetry.cpp to use just BME280 or BMP280 or GY91 not conflicting, not sure if you wanted a pull request or leave telemetry.cpp as a user edit. Happy to help in anyway I can.

what pins are you using for for i2s on esp32s3 cam wroom?

from esp32-cam_mjpeg2sd.

You can pretty much use any free pins for i2s

i tried a couple but some of them not quite ideal.
i modify them in the menu but there's what i got:
pin 14 may cause the led out of control
pin 3 or 4 may interrupt the camera
it worked immediately after pressing the reset button, but not working after a reboot
pin 46/47/21 works but it only records sound in the first 3 seconds
i will try other pins later or maybe reinstall the app

What is the pin map of your board. Sorry I don't have that board.

i bought the esp32s3 from the link

i don't know if this pin map is correct, the board looks the same

Are you talking about microphone or speaker

Are you talking about microphone or speaker

sry, microphone. i didn't think about using i2s as a speaker. maybe i reply in a wrong issue

from esp32-cam_mjpeg2sd.

47,21,42,41,1,14 should be free pins according to pin map. Yes this a feature request for i2s speaker. Not issue about microphone, I have no issues with microphone that I have noticed

from esp32-cam_mjpeg2sd.

the tricky thing is when i used pin14 it kept led on. idk why

from esp32-cam_mjpeg2sd.

Wrong place for issue. Create a issue, if there is a issue with a selected board in appGlobals.h

from esp32-cam_mjpeg2sd.

Implemented code in v9.7.1 to stream device microphone via browser to speaker on esp32. This works fine on my VoiceChanger app, but not on this app due to lag probably as too much else going on. The speaker code and notes is in audio.cpp

from esp32-cam_mjpeg2sd.

For the life of me, I could not find the setting. Need to change appSpecific.cpp config going to submenu 9, not 3. Just found the issue, but there is no time to fix.

from esp32-cam_mjpeg2sd.

Sorry, I did that to hide the parameters so it wouldn't confuse anyone else, in your copy change 9 to 3

from esp32-cam_mjpeg2sd.

Glad I worked it out lol, sorry not going to be able to test till about Sunday
