Sound Level Meter with ESP32 and I2S MEMS microphone
I am trying to get your standard code working with a ICS43434 microphone connected as follows: #define I2S_WS 22 #define I2S_SCK 23 #define I2S_SD 5 I can see the I2S...
Hello, I'm working on the ICS-43434 sensor. I want to run this code on STM32 IDE but struck over the file SOS_IIR_Filter.h and the line is struct SOS_IIR_Filter. since I'm...
I can calculate sos and gain of b-weighting through the similar way of calculating a&c weighting. but the high freq part is not perfect, and descending too fast. could you...
Hi, I have used the following repo [esp32_sdcard_audio]( https://github.com/atomic14/esp32_sdcard_audio) to build an rotary phone to store voice messages on an SD card. It's work quite good now and I will...
I found on aliexpress quite cheap i2s mems board, eg. https://www.aliexpress.com/item/33054636550.html Sellers state it is using MSM261S4030H0 chip. Datasheet: http://dl.sipeed.com/MAIX/HDK/Chip_DS/%E9%BA%A6%E5%85%8B_MSM261S4030H0(%E4%BD%BF%E7%94%A8%E7%9A%84).pdf Looks better than inmp441. Sensitivity Matching within +/‐1dB Maybe you...
Hello, I am using ESP32-WROOM-32D and using ICS43434 as a mic. In the schematic, I have set the LR to HIGH so it is set in the right channel mode....
Trying to use esp32-i2s-slm with a PDM microphone TDK T3902. Changed the interface config to PDM mode, however still some issues remain and getting just inf response. Would you be...
Hello there! Thank you so much for this project, its amaizing! I've been trying to incorporate the code to a multisensor I'm creating but when the ESP reads Serial.printf("%.1f\n", Leq_dB);...
Hello, I try to get this example to run with the [SPH0645 I2S mic](https://www.adafruit.com/product/3421). I'm using an ESP32 NodeMCU Board. The pins are mapped correctly, as I can read raw...
