Hi Christos,

Yes, it's a limitation of m4a or mp4.

Thanks.

Hi Christos,

EQ example as examples/audio_processing/pipeline_equalizer, esp_audio has not support EQ.

Thanks.

Hi Christos, The esp_audio only one situation could use i2c via audio_hal for get/set volume,not i2c_bus. The configuration of the esp_audio by the `esp_audio_cfg_t`, cfg.vol_handle = board_handle->audio_hal; cfg.vol_set = (audio_volume_set)audio_hal_set_volume; cfg.vol_get = (audio_volume_get)audio...

Hi chr1st0s，

Which I2C APIS did you used ? `esp-idf/components/driver/i2c.c` or `components/esp_peripherals/driver/i2c_bus/i2c_bus.c`.

谢谢你的建议

Hi 小小攻城狮_yun,

How to reproduce your problem?

Hi dreams2084 ,
这个问题，刚在ADF上有修复（d5d7878dcdc611ed2d12b72024b4e96044da9cc3），请检查。

Hi username,

It can't open source right now.If you have any requirements for SIP, please let me know.

Hi vgonet，

Yes. You can calculate the time as size of recoding wav data/ (sample_rate * bits * number of channel /8)
