- Regular Example:
This example shows how to forge audio files that are input by ESP-ADF's multiple pipelines and then play them back.
Audio forge involves resample, downmix, automatic level control (ALC), equalizer, sonic and other processing processes. You can select which process to combine via the mask of the component_select member of the audio_forge structure.
The audio forge pipeline is as follows:
---> fatfs_stream ---> wav_decoder ---> raw_stream --->
| |
[sdcard] ---> (NUMBER_SOURCE_FILE) ---> audio_forge ---> i2s_stream ---> [codec_chip]
| | ▲
---> fatfs_stream ---> wav_decoder ---> raw_stream ---> |
┌───────┴────────┐
│ resample │
│ downmix │
│ ALC │
│ equalizer │
│ sonic │
└────────────────┘
This example runs on the boards that are marked with a green checkbox in the table. Please remember to select the board in menuconfig as discussed in Section Configuration below.
This example supports IDF release/v5.0 and later branches. By default, it runs on ADF's built-in branch $ADF_PATH/esp-idf.
In this example, you need to prepare a microSD card and two audio files in WAV format. Rename them test1.wav and test2.wav, and copy to the card. Finally, insert the card into the development board.
The default board for this example is ESP32-Lyrat V4.3. If you need to run this example on other development boards, select the board in menuconfig, such as ESP32-Lyrat-Mini V1.1.
menuconfig > Audio HAL > ESP32-Lyrat-Mini V1.1
If you need to modify the audio file name, please enable FatFs long file name support.
menuconfig > Component config > FAT Filesystem support > Long filename support
Build the project and flash it to the board, then run monitor tool to view serial output (replace PORT with your board's serial port name):
idf.py -p PORT flash monitor
To exit the serial monitor, type Ctrl-].
See ESP-IDF Programming Guide for full steps to configure and build an ESP-IDF project.
