- Regular Example:
This example uses an ADF API to playback and record audio simultaneously. In the playback pipeline, you can choose to obtain MP3 audio from a microSD card or an HTTP server. In the recording pipeline, you can choose to store the recorded data in the microSD card or directly use it for speech recognition.
The playback pipeline is as follows:
[sdcard] ---> fatfs_mp3_reader ---> mp3_decoder ---> i2s_stream_writer ---> [codec_chip]
^
| (CONFIG_OUTPUT_STREAM_HTTP)
[http_server] ---> http_stream_reader ---
The recording pipeline is as follows:
[mic] ---> i2s_stream_reader ---> resample_filter ---> fatfs_stream_writer ---> [sdcard]
|
(CONFIG_INPUT_STREAM_ASR) |
---> raw_reader ---> wakenet_model ---> [asr_relsult]
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/v3.3 and later branches. By default, it runs on ADF's built-in branch $ADF_PATH/esp-idf.
Prepare a microSD card. Go to Audio Samples/Short Samples page to download the audio file ff-16b-2c-44100hz.mp3, rename it test.mp3, and copy it to the microSD card. Of course, you can use your own audio sources, if they are renamed according to the above rules.
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
Configure the Wi-Fi connection information first. Go to menuconfig> Example Configuration and fill in the Wi-Fi SSID and Wi-Fi Password.
menuconfig > Example Configuration > (myssid) WiFi SSID > (myssid) WiFi Password
You can select and configure the target of the recorded data, either used for automatic speech recognition (ASR) or directly written into the microSD card.
menuconfig > Example Configuration > Input stream selection > (X) record for ASR
|
--> ( ) record and save to sdcard
You can also select and configure the source of the audio, obtained from either the HTTP server or the microSD card.
menuconfig > Example Configuration > Output stream selection > (X) play music from http
|
--> ( ) play music from sdacrd
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.
- After the example starts running, it connects to the Wi-Fi hotspot as configured by default. After a successful connection, it plays the MP3 audio file obtained from the HTTP server. The log is as follows:
