I will try that.
Hello,
I 've tried it. But is was no success.
It looks like the client misses some bytes now and then.
In de debug output I see in the original version:
D: ICY 200 OK
D: icy-notice1:
This stream requires <a
href="http://www.winamp.com/">Winamp
D: icy-notice2:SHOUTcast Distributed Network Audio Server/Linux v1.9.8
D: icy-name:NAXI LOVE RADIO (NAXI,Belgrade,Serbia, NAXI,Beograd,Srbija) - 128k
And in de async version:
D: ICY 200 OK
D: icy-notice1:
This stream requires <a
href="http://www.winamp.com/">Winamp
D: icy-notice2:SHOUTcast Distributed Network Audio Server/Linux
v1.9.8
icy-name:NAXI LOVE RADIO (NAXI,Belgrade,Serbia, NAXI,Beograd,Srbija) -
128k
So at least one linefeed is missing. After that, the separation between mp3-data and metadata is not possible.
You will find the new source below.
Greetings, Ed.
//**
//* Esp_radio -- Webradio receiver for ESP8266, 1.8 color display and VS1053
MP3 module.
//* With ESP8266 running at 80 MHz, it is capable of handling up to 256 kb
bitrate.
//* With ESP8266 running at 160 MHz, it is capable of handling up to 320 kb
bitrate. *
//**
// ESP8266 libraries used:
// - ESP8266WiFi
// - SPI
// - Adafruit_GFX
// - TFT_ILI9163C
// - EEPROM
// - ESPAsyncTCP
// - ESPAsyncWebServer
// - FS
// - ArduinoOTA
// A library for the VS1053 (for ESP8266) is not available (or not easy to
find). Therefore
// a class for this module is derived from the maniacbug library and integrated
in this sketch.
//
// See http://www.internet-radio.com for suitable stations. Add the stations of
your choice
// to the table "hostlist" in the global data secting further on. This will be
written to
// EEPROM and can be modified through remote access through the web server.
//
// Brief description of the program:
// First a suitable WiFi network is found and a connection is made.
// Then a connection will be made to a shoutcast server. The server starts with
some
// info in the header in readable ascii, ending with a double CRLF, like:
// icy-name:Classic Rock Florida - SHE Radio
// icy-genre:Classic Rock 60s 70s 80s Oldies Miami South Florida
// icy-url:http://www.ClassicRockFLorida.com
// content-type:audio/mpeg
// icy-pub:1
// icy-metaint:32768 - Metadata after 32768 bytes of MP3-data
// icy-br:128 - in kb/sec
//
// After de double CRLF is received, the server starts sending mp3-data. This
data contains
// metadata (non mp3) after every "metaint" mp3 bytes. This metadata is empty
in most cases,
// but if any is available the content will be presented on the TFT.
// Pushing the input button causes the player to select the next station in the
hostlist (EEPROM).
//
// The display used is a Chinese 1.8 color TFT module 128 x 160 pixels. The
TFT_ILI9163C.h
// file has been changed to reflect this particular module. TFT_ILI9163C.cpp
has been
// changed to use the full screenwidth if rotated to mode "3". Now there is
room for 26
// characters per line and 16 lines. Software will work without installing the
display.
//
// For configuration of the WiFi network(s): see the global data section further on.
//
// The SPI interface for VS1053 and TFT uses hardware SPI.

Reset circuit
//
// The reset circuit is a circuit with 2 diodes to GPIO5 and GPIO16 and a
resistor to ground
// (wired OR gate) because there was not a free GPIO output available for this
function.
// This circuit is included in the documentation.
// Issue:
// Webserver produces error "LmacRxBlk:1" after some time. After that it will
work verry slow.
// The program will reset the ESP8266 in such a case. It seems that this error
will show up
// less frequently if DNS is not used. Now we have switched to async webserver,
maybe that
// results in a better stability.

Somehow I can not see the source, but I was able to get the sketch running here and listen to some music, so I'll give it a go also. Bytes should not be missing
Here is the source. Esp_radio_async.zip
really interesting! I tried different stations and it's always that byte that is missing? always before icy-name... looking deeper... btw I meant to use AsyncClient instead of the Sync one, but I'll look into that too.
Sorry, it was the wrong source indeed. Her is the right one (I hope). Esp_radio_async.zip
this is nice :) i finally found a problem with assimilating data. Onto fixing it... Issue is that data is acked too early and the heap get's emptied quickly
delaying Acks fixed SyncClient (result is in latest git). What it showed though is that the ESP will not be able to handle the data asynchronously, because the rate of incoming packets and rate of consumption differ much. On another note, I totally removed the 20K buffer and the streams are playing fine (since you fill the buffer and right after that you read it, you can just skip it and use the buffers that the clients have).
Performance of SyncClient vs WiFiClient will not differ, and to be honest, in your exact case, you are better off using the regular WiFiClient to buffer the stream, because it uses the TCP layer's own packet buffers and saves a bit of transactions with the memory that way.
I saw you are trying to start MDNS. MDNS is now a global service and is started by ArduinoOTA.begin()
or just MDNS.begin(hostname)
. to change the default hostname for MDNS you can call ArduinoOTA.setHostname("ESP-radio");
before ArduinoOTA.begin();
Okay. I will stick to the regular client. I introduced the circular buffer for better performance on high bitrates only. Lower bitrates will work without the ringbuffer.

Ed,
Awesome work, have one already knocked up and playing my fav stations, have you thought about adding the parametic EQ functions for bass and treble?
Great work mate, well done
Dans
Thanks for kind words. In the sourcecode you will see a remark on bass and treble as a "todo". The next version will also save settings (preset and volume) over a restart. Ed.

Fantastic, roll on version 2 Woooo
Cheers mate

Hi @Edzelf ,
Do you have some sample routines to increase / decrease bass and treble parameters?
I now have added a simple 5 button push button panel reading from the analogue input pin, allowing me based on the 100 ms timer to increment / decrement preset, I would like to use the other buttons for EQ bass and treble for now.
Big thanks buddy and so impressed with the quality of the streams I have added :)
Cheers
Dans
The new published version has bass/treble control. Don't forget to upload the index.html as well.
Ed, you are simply a Guru, just got in now really excited to see how this has been implemented.
I was racking through the datasheet last night and came up with a superb idea, I am sure you may have thought about this. What about turning this the other way around and making an ESP-MP3-Encoder?
The board I have is the same as yours, the idea would be to reverse your operation and to stream the MP3 microphone encoded to a version of the radio code to pick up the stream and in effect create a point to point audio link. What do you see as the main complexity's involved with this?
Adafuit have implemented a ogg example recording to SD card, the initialization is pretty simple although will require a plugin for the vs1053 which is available. This would be seriously cool and allow for high quality point to point streaming.
Well done mate, keep up the awesome work.
Dans
Nice idea. Technically it is interesting. The sender can act as an accesspoint, that makes it portable. A complications might be the synchronization: what happens if the sender and receiver differ only slightly in bps-speed... The coding have to be ogg, because the VS1053 cannot encode MP3. I will do some experimenting with encoding, but personally I have no usefull application for point to point streaming.
Hi Ed,
I think it would be a really cool project. Thinking about operation, the client "sender" attempts connection to the server basically the mp3 decoder running ogg. Basic socket connection and then some form of simple authentication, I.E chip id is sent from client, server checks validates and then sends a command back to client to start sending the stream, maybe this approach would allow synchronization to take place, I don't know a lot about ogg format and will be researching this now. Would be superb if you get a chance to tinker with the encoding and send stream side. I think this system would only work point to point due to ESP limitation in remote connections, but would be really cool concept.
Glad you are interested in this, what other stuff do you get up to in your day job?
Big thanks
Dans

Ed,
Wow so excited, well done you, had a look through the code, awesome mate. Just ordered another VS1053 board to try. I think for an interim I can use winamp to connect and test, will give this a go in the short term.
Any major issue's you encountered while putting this together? how did you test it and where you impressed with audio results?
Superb work, cheers Guru

Dans, It was not that difficult to cut and paste things together. Major problem was (again) the fact that GPIO[0] and GPIO[1] are floating on my cheap Chinese board. Then the conversion stops right after generating the Ogg header (699 words), see http://www.vsdsp-forum.com/phpbb/viewtopic.php?f=7&t=595&sid=b902cfa400af926. Another problem is that sometimes the initialization of the board fails. After one or 2 resets it starts suddenly and it will work for hours. I will try to find out what the problem is.
I tested it with Firefox, and the quality (microphone input) was good. I noticed a delay of 2.5 seconds. I tried Winamp, but no success.
Have not tried the Esp-radio yet, but it should work.

Ed,
Amazing work, I have just downloaded Firefox and yes all connected up fine same view as yours connection alive, I am using the onboard microphone but no sound is coming through, did you use an external mic or line input?
Those chinese cheap boards are a pain, I have this knocked up on a NODEMCU, I have changed original pins 4 and 5 and swapped to GPIO 0 and 2 as using I2c. works perfect on ESP radio, not sure if this is causing the no sound issue on ogg encoder?
I will keep tinkering, A plus mate

Dans, I used the microphone. During conversion, you can monitor the sound through the headphone connection.
I made some changes to Esp-radio and Ogg-encoder and now the radio can receive data from the encoder. Issue: the radio reads a bit faster than the encoder produces. So the ringbuffer is always empty. I replaced boths sketches to http://smallenburg.nl/Ogg-encoder.zip. You can also find my mailaddress on the website, so you can mail me directly.
Ed,
Awesome work buddy, sorry for delay had to re build all data on to new laptop, my old one suddenly decided to type when no keys pressed lol. Too much programming for it Haha.
Super stuff buddy, I did try the last encoder and found that although mozilla locked on to the stream no audio would come through, I did plug in to the headphone socket and audio was their from the microphone strange. I will get some time hopefully next week to follow this up, finishing off my garden lighting system since the weather is really nice, features 5 outputs all PWM controlled by android app on my phone, I will send over some pics when up and running.
Keep up the amazing work.
Dans
Since I see you already have the Async server up (yeah! :)), why not move the mp3 stream to async as well? You will not need to buffer the client and you can write to the VS1053 as data comes. Using that will also ACK the data only after you have it loaded to the VS, which will make networking a little more predictable :) Let me know what you think, I can help if needed :)
