How to use other DAC chip type NS4168? #6

Closed franciscogimeno2000 closed 2 years ago

franciscogimeno2000 commented 2 years ago

Hello, thanks for your example codes. I am using a m5satck ATOM Speaker Kit with a NS4168 chip decoder, could you tell me how to implement the library of this chip so that it works with your example?

Thanks.

That would be unpossible as the ns4168 is a dac and not a codec. (So it expects/plays samples and not a coded stream)

See for example https://www.analogictips.com/what-is-a-codec/

You might try https://github.com/schreibfaul1/ESP32-audioI2S/ to decode the streams. I used that lib with a couple of different dacs and it should be fairly easy to get it running.

The stream has to be decoded before you send it to the dac which would be done by ESP32audioI2S which sends the decoded data (the samples) to the ns4168.

OK thank you very much.

CelliesProjects commented 2 years ago

Just try the example from https://github.com/schreibfaul1/ESP32-audioI2S/wiki#a-simple-project-to-receive-a-webstream, change the pin numbers to the numbers used by the ns4168 and it could very well be that it works.

franciscogimeno2000 commented 2 years ago

ok thanks, i'll try it.

franciscogimeno2000 commented 2 years ago

It seems to me that it is better to use a codec chip than a DAC. Faster, better quality and less problems. With a codec you get the transcoding of the flow done and you avoid noise, latencies and, as I say, problems. Ultimately more professional.

CelliesProjects commented 2 years ago

I can only agree with that. I started out with software decoding and after a lot of hassling ended up -very satisfied- with a hardware decoder.

franciscogimeno2000 commented 2 years ago

I have been using your library and with the codec chip vs1053 the sound is perfect. One question, is your library capable of automatically reconnecting if the server goes down? Or do I have to read the playback status and launch it again

franciscogimeno2000 commented 2 years ago

Another thing, if while it is playing I deactivate the server, the ESP32 gives a panic message and restarts. I don't know if it happened to you.

this is my network server: stream.connecttohost("http://192.168.0.145:8080");

Rebooting...

CelliesProjects commented 2 years ago

Interesting. I assumed -and the code does- that radio streams never stop. And as you probably know assumption is the mother of all fuckups so there you go.

What setup do you use to start/stop a stream? I want to test this scenario in my network.

franciscogimeno2000 commented 2 years ago

Use any vlc type player and generate a streaming of an mp3 and when it is playing do not hit the vlc stop, close it directly.

franciscogimeno2000 commented 2 years ago

I have also tried to remove the wifi while playing, and in that scenario no error occurs. With which I believe that the problem is in the reproduction, not in the management of the wifi or the client.

CelliesProjects commented 2 years ago

Thanks, got the streaming part running. Next thing is debugging. Stay tuned...

franciscogimeno2000 commented 2 years ago

ok

franciscogimeno2000 commented 2 years ago

One question... do you know how to synchronize several esp32 so that when connected they play the audio at the same time?

I have read that the WMA protocol sends the real time of the current position of the player in the encoding. But I don't know how to read this.

CelliesProjects commented 2 years ago

I am getting "application/octet-stream" mime-type headers from the local vlc streamer on all filetypes. You are using macOS of windows?
