ESP8266 Audio | Play audio file with Esp8266 or Nodemcu without SD CARD

[@shivanSpS]

This works rather well, dont expect super clear or very loud sound but it can still produce a fairly good sound. For anything better you will need to use a external I2S DAC. I would also recomend not to upload to PROGMEN like it is showed here, thats OK for a simple test, but it is way better to use LittleFS on the ESP8266 and SPIFFS on ESP32, for one simple reason, PROGMEN is limited to 1MB and the LittleFS partition can be up to 3MB on a 4MB ROM model (you can select how you partition the ROM on the arduino IDE), by using LittleFS you can upload the file directly to the ESP using the plugin for the arduino IDE. On this way you can also use AAC, FLAC or MP3 files that are way smaller than a WAV. There is even a ESP-01S with a 8MB flash you can partition to have 7MB LittleFS, and this code runs out of the box on it since it uses the RX pin that it is avalible on the ESP-01.

Great project, thank you! What is the amount of flash memory available on the ESP8266 that can be used for the sound file? In other words, how much memory space does the sketch needs without considering the audio file? What I'm trying to find out is how big the audio file can be, before the ESP 8266's storage memory is full... Thanks!

Please give answer 01. How much seconds long audio we can put in esp 02. How to apply 3 times loop 03. How to amplify audio Signal

that's one hell of pretty beaten up little veteran speaker ... don't you thing it's time to retire him?

[@andrewandrosow4797]

Hello! Good video! Can a esp8266 moduletransmitt audio (for example 8kHz 8bit digital sound ) to another esp8266 module with a speaker? I mean using only NodeMCU (maybe C++), because assembler is very difficult ..especially for me))

[@brandontechnerd]

Is it possible to stream the audio from the SD card using a buffer? This would be theoretically possible due to the ESP8266's massive 80 KBs of RAM.

Wow thank you its nice project but i have 2 questions. can i use this code with wemos D1 R1 micro-controller? and the other question is ....... by using NODMCU ESP8266 micro-controller and by modifying the code, can I play 3 different audio sequentially?

[@electronicGURU]

Yes you can.

It works! Now It seems like If I made it, then it will not be like something very good. I am unable to get a loud and super clear if I make it.

[@techprolet]

Thank you for the great tutorial! Have you been able to measure power consumption of the setup? I would be interested to power this with a cr2032 button battery, which would not go above ~80mAh (peak).

Very good video bro, awesome, can you make video producing engine car sound using this

[@electronicGURU]

Well you can do it on your own , download some engine audio from web and use it here.

[@jayaram00001]

This is really useful. Do you know a way to use an amplifier like pam8403 instead of TIP120 transistor ?

[@electronicGURU]

I mean to be honest i tried but it didn't gave a good output. So this is more of a educational less of a practical use

[@surflaweb]

what's the value of the resistor? 42 ohm?

[@isidrorosales476]

bro, can i use 2N2222 npn instead of TIP?

hi, have you turorial with playing some samples from sd card by uno or esp?

[@electronicGURU]

No sir ,very sorry but i don't have.

[@abhishekreddy2425]

Did you notice that it plays only once when NodeMCU is booted? You have to press reset again to play more than once... What's the way to implement in your project code and still be able to playback any no. of times when it is called?

[@electronicGURU]

Yes it does that, because the begin method is used in setup and in loop part we put a if condition to stop it so i hope you get the idea.

[@abhishekreddy2425]

@@electronicGURU Ok, so if we simply remove the condition to stop from the loop and begin it only once in setup we can call any no. of times right...

[@electronicGURU]

I haven't tried but i think it could work. Or try to begin it in loop as well.

Hello, sir! What could you say about the audio fidelity? I'm about to build and Loop Station for guitar using ESP866 with and ADC converter (PCM1802), but I'm not sure about the sample rate and possible delay when using esp8266 as a DSP.

[@electronicGURU]

To be honest noticable delay would be there and audio could be okay okay types but not very pleasant.

Thank you for the video, but i have one question, can be TIP120 replaced by TIP122 ? because i hate to waiting shipping online guy 3-5 day.. i want to test it before asking, but i want to find out more info before something bad happens. :) hope somebody will answer my question. Thank you

[@electronicGURU]

well its a general Darlington pair USE case scenario any Darlington pair transistor would work , even you can use two small BJTs to make a Darlington and it will work. Even you can run with a simple BJT , the only difference you gonna see is in output, depending on transistor power delivery and other characteristics the output would be low or high , clear or unclear, but you will get output no matter what and i think TIP122 will do just okay

[@kannadanudi8444]

How can we, play continuously (infinite)

ok so when you edit the audio in audcity decrease the sound simply.

ok is also doable but it great idea to make the wave amplitude small in audacity which will reduce the sound for sure
