alirezasalehy / wavrecorder

Arduino Library for voice recording using Electret Microphones for ESP32, ESP8266 and Arduino Due.

Hi, I'm Alireza   

• As a passionate embedded systems engineer and modern C++ programmer, I have honed my skills in STM32, ESP32, and AVR MCUs, and their respective platforms including STM32Cube, Arduino, and Codevision and developed an open source user friendly lib WAVRecorder. I'm also highly interested in computer networks and database concepts and contributed to courses Embedded systems and Assembly (as head TA), Computer Networking and Principles of Database Design at AUT during my BSE designing HWs and Embedded systems' lab materials.

• Currently studying for MS.E in AI at UT with focus on Anomaly Detection leveraging Knowledge Distillation and maybe Vision-Language Models. I welcome opportunities that deepen my knowledge and fulfill enthusiasm in the field, especially if it's associated with the IoT workspace (which is my enduring passion).

wavrecorder's Issues

How to use with Flash Memory in ESP8266?

How can I use the WAVRecorder without an SD card and with the flash memory that comes with the esp8266?

Will this work using an analog audio source like a line-in?

Library not Valid

I cannot add this zip file to my arduino ide this error comes in the monitor
Error: 13 INTERNAL: Library install failed: moving extracted archive to destination dir: library not valid

Components

Which Hardware did you use besides the microphone and the arduino due? How is the hardware connected/ How is the setup?
Can you share a schematic or a picture of the hardware construction?
Thanks in advance

Zip file is not adding to Arduino ide

When I add zip file to Arduino ide library It's showing error like
error: 13 INTERNAL: Library install failed: moving extracted archive to destination dir: library not valid
Please give me solution

hwo is the output played?

In your example circuit I don't see an output/pin.

how is the audio played on a speaker and here is the setup of the output pin?

thx

Record as long as I want

Is there any method to record audio as long as I press a button? Like a proper recorder

reboot all again at esp32
