In this example, we use `esp_codec_dev` dependency which contains the `es7210` driver. This driver uses `ES7210_I2S_FMT_I2S` format by default.

Recorded voice will be saved to SD card in `wav` format, and can be played or processed on PC.

The component can be installed by [IDF Component Manager](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/tools/idf-component-manager.html). This example already includes it.

* Change value of `EXAMPLE_I2S_FORMAT` to check I2S driver's functionality on different I2S formats.
|
||||
* Change `EXAMPLE_ES7210_MIC_GAIN` and `EXAMPLE_ES7210_MIC_BIAS` according your MIC's specs if needed.
|
||||
* Change `EXAMPLE_ES7210_ADC_VOLUME` if recorded voice is too loud or too quite.
|
||||
|
||||
Note: it's better to adjust `EXAMPLE_ES7210_MIC_GAIN` first. If adjusting MIC gain doesn't meet your demand, you can then adjust `EXAMPLE_ES7210_ADC_VOLUME`. That is to say, it's better to adjust analog gain than digital gain.
|
||||
The configuration macros are defined at the beginning of `main/i2s_es7210_record_example.c`, you can change the configuration macros according to your needs.
