SqueezeEsp : The cheaper squeezebox in the world

[brjhaverkamp]

This indeed looks awesome.

What DAC did you use?
My personal usecase would likely be speaker based. With a MAX98357A or similar.

Did you get further with the slim protocol?
Let us know. And please please open a github for the source, in whatever state it is in! We can all support improving it and and make this happen.

Just like to say, I think this looks very cool too!

I used the mp3 decoder from MrBuddyCasino on an ESP32, without DAC, just to see how the quality was.
It's not bad, I guess it can be compared to FM radio with mediocre reception. Much better than I expected, anyway.

I tuned it to stream.mp3 on my LMS server, and this worked quite alright. There is quite some lag when controlling it due to streaming, but thats ok for zero effort I guess.

There is also this project https://github.com/karawin/Ka-Radio Ka-Radio and https://github.com/karawin/Ka-Radio32 Ka-Radio32 which further expands on this work.
There is also an Android app to remotely control the radio.
Maybe this can server as a starting point, since streaming and control protocols are already implemented?

Not sure how much memory is available when this is flashed though....

That is impressive. Up to 320kbps MP3 plus a method to play other formats by adding more hardware and it is being actively worked on.
If the developer can be persuaded that LMS would bring a lot more options ... then maybe would help/advise on implementing Squeezelite/Slimproto.

Yes, the ESP32 is much more powerful than the ESP8266. And I did not get any stutters through WiFi, even without extra SRAM as buffer. Granted, I was next to the WiFi AP, but still...

I'd be happy if the ESP could work as a regular client without going through stream.mp3, as a first step. Not sure how much of the squeeze procotol would have to be implemented, but I guess the squeezelite and squeezeslave sources can give insights on that.

I think this is really cool, but my first thought was the old saying: "Just because you can, doesn't mean you should!"

I have finnally receive my ESP32 and the vs1053 module. They can decode 320kbs stream wihtout any trouble. Sound quality seems to be good to. I get some issues after few minutes and the 'command socket' stop to receive any packet from the LMS server. Probably a bug in my code.

I have prepare a projet on github to share my source code but i have to clean it a little bit before push it. It will be a very basic version for start.

[Paul Webster]

That is good news and welcome back.

Command issue is fixed now. I was able to play MP3 et ogg file but i get no sound with flac format. Streaming seems ok but no sound get out the module vs1053. I read on the net that old version of the vs1053 needs 'plugin' to play flac files. I will investigate this part later. For now i have to analyse more in details the slimproto because at the end of a song, the server do not start the next one. I have probably miss something in the protocol.

AFAICT VS1053 doesn't support flac - so I think you'd have to make sure LMS can convert Flac to MP3 (i.e. lame has to be installed) - slimproto HELO packet tell LMS what audio formats are supported by the player.
