Espressif has launched **ESP Audio Analyzer**, providing a convenient and efficient testing approach with a standardized process, combining an intuitive web interface with supporting test firmware to enable standardized audio testing. Using this tool, users can comprehensively test microphones, speakers, and AEC functionality and performance, quickly identify and troubleshoot issues in audio systems, thereby effectively improving development efficiency and product quality. Key features include: - Comprehensive functionality: Covers microphones, speakers, and AEC — 11 audio tests in total - Easy adaptation: Based on ESP Board Manager, supports rapid adaptation to different hardware - Performance analysis: Provides audio metrics such as THD and SNR for evaluating system performance - Standardized process: Unified test methods and pass/fail criteria - Source data download: Supports exporting original recording files for retesting and in-depth analysis - Visual reports: Generates structured test reports with data, charts, and test results ## Example Set Up ### IDF Default Branch This project is compatible with ESP-IDF release/v5.4 (>= v5.4.3) and release/v5.5 (>= v5.5.2) branches. ## Prerequisites ### Environment Requirements To ensure the accuracy of test results, the testing environment should be an anechoic chamber or a quiet environment (background noise less than 30 dB). ### Equipment Requirements The ESP Audio Analyzer testing project uses a computer as the testing platform. The following equipment is required: - Computer and router: The computer is connected to the router and can access the ESP Audio Analyzer web page (`https://audio-tools.espressif.com.cn`) - Device under test: Requires at least 4MB Flash, PSRAM recommended, supports playback and recording functions, and can connect to the router via Wi-Fi - Playback device: Use high-quality audio equipment such as speakers, requiring no distortion during playback and a flat frequency response curve in the 100Hz-8KHz range - Recording device: Use a computer microphone or external microphone for recording - Testing tools: Sound level meter, modeling clay (for blocking microphone pickup holes) ### Configuration 1. Wi-Fi Configuration Configure Wi-Fi SSID `WiFi STA SSID` and password `WiFi STA Password` in `menuconfig -> Example WIFI Configuration`. 2. Test Function Configuration Configure AFE functionality in `menuconfig -> Audio Test Solution Configuration`. Note: When enabling wake word and voice command recognition, at least 8MB Flash is required, and the `partitions_sr_model.csv` partition table must be used. - AEC enabled by default: `Enable AEC` - Wake word recognition disabled by default: `Enable Wakeup` - Voice command recognition disabled by default: `Enable Voice Command` After enabling AFE functionality, further configure AFE-related settings according to the hardware design: `ESP GMF Loader -> GMF Audio Configurations -> GMF AI Audio -> Initialize GMF AI Audio AFE -> Audio Front-End (AFE) Configuration` - `Feed Task Setting` and `Fetch Task Setting`: Task-related settings - `AFE Channel Allocation`: Configure microphone channel information according to the hardware design, using `M`, `R`, and `N` characters to represent microphone, reference signal, and unused channels respectively The `Enable store test audio in embed flash` option is enabled by default, embedding necessary audio files to be played into the firmware to reduce dependence on network bandwidth. 3. Partition Configuration Configure the partition table in `menuconfig -> Partition Table`. - Default uses `partitions.csv` partition table - When enabling wake word and voice command recognition, the `partitions_sr_model.csv` partition table must be used, or customize the partition table size according to log information ### Build and Flash Before building this example, ensure that the ESP-IDF environment is configured. If already configured, skip to the next configuration step. If not configured, first run the following scripts in the ESP-IDF root directory to set up the build environment. For complete steps on configuring and using ESP-IDF, please refer to the [ESP-IDF Programming Guide](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/index.html): ```bash ./install.sh . ./export.sh ``` - Execute the prebuild script, select the target chip, automatically setup IDF Action Extension, use `esp_board_manager` to select supported board and custom board On Linux / macOS, run following command: ```bash source prebuild.sh ``` On Windows, run following command: ```powershell .\prebuild.ps1 ``` - Use `esp_board_manager` to select supported board and custom board, be sure to see [ESP Board Manager](https://components.espressif.com/components/espressif/esp_board_manager), taking ESP32-S3-Korvo2 V3.1 as an example: ```bash idf.py gen-bmgr-config -b esp32_s3_korvo2_v3 ``` - Configure the project using menuconfig, refer to the [Configuration](#configuration) section to modify configuration items ```bash idf.py menuconfig ``` - Build the example program ```bash idf.py build ``` - Flash the program and run the monitor tool to view serial output (replace PORT with the port name): ```bash idf.py -p PORT flash monitor ``` - Use `Ctrl-]` to exit the debug interface ## How to Use the Example ### Features and Usage - After the example starts running, it will automatically connect to Wi-Fi and start the WebSocket service, waiting for the computer to connect ```plaintext I (1059) main_task: Calling app_main() I (1062) MAIN: [1/4] Initializing board...

Please open a new browser tab and directly access the device address printed in the logs, then click "Advanced" and select "Accept the risk and continue" on the page. After completing the trust operation, the browser will automatically redirect to the [ESP Audio Analyzer web page](https://audio-tools.espressif.com.cn/). For example, if the address printed in the device logs is `https://192.168.0.179/`. > [!CAUTION] > You must manually trust the device, otherwise you will not be able to connect to the device. - Enter the WebSocket address printed in the device logs (e.g., `wss://192.168.0.179:443/ws`) into the `WebSocket URL` input box on the [ESP Audio Analyzer web page](https://audio-tools.espressif.com.cn/), and click the `Connect Device` button. After successfully connecting to the device, select any test item and follow the prompts to perform the test. ```plaintext I (12461) APP_WS: Mic gain set to 32 dB I (12461) APP_WS: Volume set to 15 I (12462) APP_WS: Channel type set to: MRMN I (12462) APP_WS: Configured: 16000Hz, 16bit, 4ch, mic_gain=32, volume=15, channel_type=MRMN I (12506) APP_WS: Duplex: recording to ringbuffer (buffer: 1048576 bytes), AFE: disabled I (12507) APP_AUDIO: Starting recording: sr=16000, ch=4, bits=16, file=NULL, buffer_size=1048576 I (12511) I2S_IF: Paired data: 0x3fcecd04, current mode: record, paired in_enable: 0, paired out_enable: 0 I (12521) I2S_IF: TDM mode, dir: RX, data_bit: 16, slot_bit: 16, total_slot: 4, slot_mask: 0xf I (12529) I2S_IF: TDM mode, dir: TX, data_bit: 16, slot_bit: 16, total_slot: 4, slot_mask: 0xf I (12538) ES7210: Bits 16 I (12547) ES7210: Enable ES7210_INPUT_MIC1 I (12549) ES7210: Enable ES7210_INPUT_MIC2 I (12552) ES7210: Enable ES7210_INPUT_MIC3 I (12555) ES7210: Enable TDM mode I (12560) ES7210: Unmuted I (12560) Adev_Codec: Open codec device OK I (12560) APP_AUDIO: Codec device opened: sr=16000, ch=4, bits=16 I (12588) NEW_DATA_BUS: New ringbuffer:0x3c2e49f4, num:1, item_cnt:1048576, db:0x3c376ccc I (12588) APP_AUDIO: Created record ringbuffer: 1048576 bytes I (12591) ESP_GMF_TASK: Waiting to run...

You can try increasing the size of `WS_AUDIO_BUFFER_SIZE` in `app_websocket.c` - You can also try improving Wi-Fi performance by referring to the [Wi-Fi Performance Optimization](https://docs.espressif.com/projects/esp-idf/en/stable/esp32s3/api-guides/wifi-driver/wifi-performance-and-power-save.html#how-to-improve-wi-fi-performance) documentation, or reduce the distance between the device and router ### Cannot Start WebSocket Server - This is often caused by insufficient internal memory. It is recommended to enable PSRAM to preserve more internal memory space ### Insufficient IRAM During Build/Link - Please refer to the [IRAM Optimization](https://docs.espressif.com/projects/esp-idf/en/stable/esp32s3/api-guides/performance/ram-usage.html#optimizing-iram-usage) documentation to disable unnecessary optimization options ## Technical Support and Feedback Please use the following feedback channels: - For technical queries, go to the [esp32.com](https://esp32.com/viewforum.php?f=20) forum - For a feature request or bug report, create a [GitHub issue](https://github.com/espressif/esp-adf/issues) We will get back to you as soon as possible.
