Hi, I used your lib and have some problem with adc :)
I used it with adcChannel = ADC1_CHANNEL_5; and I need get value from analogRead(36).
When program comes to line with analogread it freeze.
I try adc1_get_raw(ADC1_CHANNEL_0) and still the same.
Is there any way to use lib and read value from ADC1_CHANNEL_0 ?

aaAudio.adcInterupts(false);

should be

aaAudio.adcInterrupts(false);

This causes a compile error in this example.

Could you provide an example .ino file that reads from the ADC with a fixed sampling rate and outputs it to the DAC? That would be very useful for a guitar effects project on the Arduino Due, for example.

I've been trying to code a pass-through using this library, but I couldn't quite make it...

Here's what I tried so far: https://gist.github.com/dangpzanco/10cd9ec34a38702c66015a535b142042

Edit: That code was functional, but the sound quality is awful... Maybe because the library sets up two timers, one for the ADC and another for the DAC?

The begin() function in the aaAudio library seems to be affecting the SPI bus. Attempts to find files, both images and sound, on an SD card after calling this function work, at best, only some of the time. This behavior is occurring on an Arduino Due.

Hi,
tried to use ur library to output number generated wav file, but can't get it to work. There is no playback sound at all. SDAudioBasics example working just fine (with that switch operator). I'm using Arduino Uno, here's code I'm using - basically generate random number up to 27 (which is last file on sd card -> "27.wav"), then checks if sensor value is above limit, if so the playback should occur. Thanks in advance.

#include <SPI.h> #include <SD.h> #include <AutoAnalogAudio.h> AutoAnalog aaAudio; void DACC_Handler(void) { aaAudio.dacHandler(); } int input = A4; int output = 8; int val = 0; void setup() { Serial.begin(115200); randomSeed(analogRead(A5)); pinMode(input, INPUT); pinMode(output, OUTPUT); if (!SD.begin(10)) { Serial.println("SD fail"); return; } else { Serial.println("SD ok"); } aaAudio.begin(0, 1); aaAudio.autoAdjust = 0; aaAudio.dacBitsPerSample = 8; aaAudio.setSampleRate(16000); } void loop() { val = analogRead(input); char buffer[10]; char buffer2[20]; int rand = random(1, 28); sprintf(buffer, "%d.wav", rand); sprintf(buffer2, "Status sensora: %d", val); Serial.println(buffer2); if (val > 10) { digitalWrite(output, HIGH); delay(500); Serial.println(buffer); //debug playAudio(buffer); } else { delay(500); digitalWrite(output, LOW); } loadBuffer(); } File myFile; void playAudio(char *audioFile){ if (myFile) { myFile.close(); } myFile = SD.open(audioFile); myFile.seek(44); loadBuffer(); } void loadBuffer(){ if(myFile.available()){ for(int i=0;i<32;i++){ aaAudio.dacBuffer[i] = myFile.read(); } aaAudio.feedDAC(0,32); } }

Hi, I'm new to Arduino.

My goal is to continues recording using buffer for long hours without the need to play wav files. Currently, I'm trying to test your code in my Arduino Due, MicroCard adapter and MAX9814. I understand 85% of it and try to create my own version however all the example seems to has been modify for ESP32.

1. Seems like example of ESP32 in AutoAnalogAudio/examples/SDAudio/SdAudioRecording/ has adcbuffer while older version of this example did not called this function. This confused me.

2. The example in AutoAnalogAudio/examples/SDAudio/SdAudioRecording/ also have stopRecording function that are far different than this version. I assume this also related to adcbuffer.

Hi Mr
I want to use this library to record a wav file with a microphone connected to esp 32 dev kit, but my problem is when recording the file because it starts working by pressing the 9 key first, but after pressing the 0 button for a few seconds To stop recording, this message is displayed File contains no data, exiting , and nothing is actually recorded
I used an onboard ADC 34 pin and also had another problem with this library at first and it was in the sd.h library because this library did not match esp 32 and it showed the error Failed to open file that I changed the sd.h library I fixed this error with mySD.h
What do you think is the problem for recording?
please...

Great library.
I would like to use it for ESPboy walkie-talkie NRF24 module for my www.espboy.com project
but as i see it does not support esp8266

Hi,
I was looking at this new library. Which are the differences with rf24audio library?

I want to send audio from a nord to the master using the radios. Which library is better?

Thanks!

When i use sd audio recording example with esp32 it show i2s0 is not intialised yet , is this example use i2s microphone

Hello, in my project I am trying to record sound onto an SD card using an STM32F4 microcontroller, I am wondering whether this library has support for the STM32 architecture in order to do this. Any help/ advice rendered will be greatly appreciated.

Minor artifact, if you look at scope of DAC output for example SimpleSine12Bit. Wavefrom at peak drops to zero for one sample, need to replace 0x1000 table value with 0xfff

Hello .. I tried to build an example, but I got the following output: 'error:' adcChannel 'was not declared in this scope'.
I declared the adcChannel variable in the AutoAnalogAudio.h header, so the compilation was completed without errors.

Hi, I'm using Arduino Due.
My goal is to write and save an audio with 8bit and sr = 16kHz to sd card. I'm using SdFat32. I have test run all component by itself however when I tried to combine SdFat32 and modify the code from your example, I can not initiate SdFat32 at all. It always gave me an error(can not find SdFat32).

Thank you in advance. I really looking forward to hear from you.

Hi!

Using an Arduino Nano clone with the library. Reading in audio from a keyboard (Casio Sk-1) at line level. Inputting to A0 and outputting to 9 as per docs.

Audio is successfully being read in and output through DAC to a 4ohm speaker and a rca output, but the audio is extremely distorted. Here's the wave being read in:

I tried using a PAM8403 breakout for amplification in but it didn't output anything useful. Still getting relatively low levels in.

When I plug into a power amp via rca it's EXTREMELY loud and distorted.

Thanks for help & for the wonderful library!

and simple code to recreate:

AutoAnalog aaAudio;
void DACC_Handler(void) {
  aaAudio.dacHandler();
}

void setup() {

  pinMode(A3, OUTPUT);
  digitalWrite(A3, HIGH);

  Serial.begin(115200);

  aaAudio.begin(1, 1);
  aaAudio.autoAdjust = 1;
  aaAudio.dacBitsPerSample = 8;
  
  aaAudio.getADC(32);
}

void loop() {

  aaAudio.feedDAC(0, 32);
  aaAudio.getADC(32);

  for (int i = 0; i < 32; i++) {
    aaAudio.dacBuffer[i] = aaAudio.adcBuffer[i] << 2;
    Serial.println(aaAudio.dacBuffer[i]);
  }
}

Hello,
I'm stuck on a problem regarding the communication between a sender device and a receiver (both arduino DUE with nrf24l01+).

Firstly, if i run pingpair_ack from rf24-library example then everything is working (I can see the ping-pong packet flowing with acks). But I had no succes with the SimpleSine deployed to the sender, and the WirelessSpeaker deployed to the receiver.
Same bad result with audioRadioRelay deployed on both devices.

The first debugging shows that the RX() function on the receiver is called only one time with pipeNo=0 but then it never goes inside the while (radio.available(&pipeNo)). So it seems to me that no radio data is available to the receiver.

If I deploy the SimpleSine and WirelessSpeaker, am I suppose to listen the sine from the DAC0 of the receiver without any change to the code? The sine plays well from the DAC0 of the sender..

Thanks for the support

Hi dear, I'm having an issue with the AutoAnalogAudio.h , I'm using esp32 board. The problem happens
when I include in my project the Audio.h library, I upload my code to the board no problems but when
I use the Audio.h library the library throws this message:

Analog Audio Begin
E (37) I2S: /home/runner/work/esp32-arduino-lib-builder/esp32-arduino-lib-builder/esp-idf/components/driver/i2s.c:1252 (i2s_adc_enable):i2s built-in adc not enabled

It says "i2s built-in adc not enabled" I don't know if there is a way to enable adc, I'm not esp32 expert, it is for that reason that I'm writing this issue to ask for help.

The library AutoAnalogAudio.h works well when I record audio, however when I include the Audio.h library it throws that message and I'm no unable to record audio because the board starts to reboot.

Hi, is there any solution how to record from max 9814? I try record by this mic, but recorded file is so distorted and indistinct.

I am trying to use a microphone with my NodeMCU V2 board and stream audio PCM data to a service over WIFI. I am using PlatformIO IDE to program this board. Last time I tried using this, it gave an error(undefined reference to functions) while compiling to ESP8266 target. I am not sure it is because of lack of support for ESP8266 board or I am missing some compiler options. Could someone help? @TMRh20

Does this library support esp32?

I tried but receive a lot of errors, especially with the registers.

Tried with pro micro and teensy 2.0, esp32 firebeetle, atmega2560.
Tried WirelessMicrophone, WirelessSpeaker.I put a microphone on the sender pin A0(I could see the signal with the oscilloscope) and probed all the pins on the receiver and nothing.
(attachInterrupt(digitalPinToInterrupt(4), RX, FALLING); does not work, there is no signal activity on the nrf24l01 pins; I put RX(); in loop and I see activity)

I used SimpleSine example on the sender(I could see the signal on the sender pins 9,10), uncommented lines to enable radio, probed all pins on the receiver and nothing.

Simple radio example hello world works.

Good evening everyone. I want to use the library https://github.com/TMRh20/AutoAnalogAudio on ESP32. But in the program I don't know where to define my microphone input. And so I don't know where to connect it to the esp board. Please help me.

Hello @TMRh20 I have made a connection to the arduino due using a max4466 mic as well as an sd card, tried using the sdaudiorecording library but it keeps popping an error failed to start recording, could you help with an example that I could use with the arduino due to be able to acquire an audio sample from the mic, thank you

TMRpcm couldn't compile for Arduino micro (just using to test your libraries first) but I get error fastadc:50:21: error: 'class TMRpcm' has no member named 'startRecording' same for stopRecording. So I turned to try AAAudio. Both libraries were installed by searching inside Arduino ide library manager. I tried running the SimpleADCStream example but get error ```C:\Users\AKIRA~1.KAT\AppData\Local\Temp\ccK7SMga.ltrans0.ltrans.o: In function `__vector_13':

C:\Users\akira.kato\Documents\Arduino\libraries\AutoAnalogAudio\src\avr/AutoAnalogAudio.cpp:212: undefined reference to `DACC_Handler()'

collect2.exe: error: ld returned 1 exit status ```. I try setting board to Arduino nano to try to just compile since it saids in wiki it works but the compilation failed for same error.

Hi,

Thank you for this great library.

I am willing to generate a sound wave that is higher than 40Khz. can this be achieved with wav files and this library?

Best,
Rani

Any instructions on how to use with SDfat? also does it work on a Arduino Zero?

Iam using AutoAnalogAudio library for Audio Recording using esp32 but my audio recording speed is too fast is there is any solution for that

Hi Mr
Is AutoAnalogAudio work with esp32 boards?
And if it works, with what kind of esp32 board's?

c:\Users\*****\OneDrive\Documents\Arduino\libraries\AutoAnalogAudio\src/AutoAnalogAudio.h:258:3: error: 'adc1_channel_t' does not name a type; did you mean 'i2s_channel_t'?

   i2s_channel_t

I'm using the Arduino IDE to try to record audio using the XIAO Sense and an external electret microphone. I followed the setup outlined in the documentation before uploading any code. I'm wondering if there's a missing dependency that wasn't installed initially or if it's a more underlying issue.

I'm not sure what exactly the problem is as I'm not too familiar yet with the auto updating of Github Pages from doxygen, so hoping @2bndy5 will come to the rescue.

G'day

I have been looking for a solution to play one and two word audio/pcm files from flash memory on the Nano33BLE board with no luck. The many solutions for this on other Arduino format boards don't work on the Nano33BLE.

Is there a solution with this player that someone can help me with?

Is it possible to stream not only video but also audio with esp-cam?

Esp-cam has pinout gpio12 ~ gpio14 that can do adc ，but these pins are of adc2，and i2s driver seems to be hard coded with adc1

This article says adc2 is use by WiFi on esp dev board，I guess it likely the same with esp-cam

esp-cam pinout and schematic
https://randomnerdtutorials.com/esp32-cam-ai-thinker-pinout/

That's too deep for me. I wonder if you are interested and have time to look into this question

Hey there!

Whenever I try to compile even the basic examples included in this library for my ESP32-S3 (Adafruit Feather ESP32-S3 TFT) I get the following error. I'm no pro with Arduino and C/++ in general and I can't really pinpoint the error source, but I think it could be related to the ESP32-S3 being rather new and this lib maybe not updated yet?

libraries/AutoAnalogAudio/src/AutoAnalogAudio.h:235:3: error: 'adc1_channel_t' does not name a type; did you mean 'i2s_channel_t'?
   adc1_channel_t adcChannel;

sup guys, i was trying to record some stuff with a old mic module and the esp32 module by itself, with sd card. but im having this problem when i send de record option to serial monitor, as you can see below

im using the sdaudiorecording.ino example, an esp32 regular board and an analog mic
by the way sorry for the bad english :(
