ESP32-WROVER-B WiFi <1.2Mbps

Hi, We have been testing the download speed of ESP32-WROVER-B WiFi using a modified version of esp-idf example “esp_http_client_example”. The download speed, either from Amazon or from Dropbox download link, doesn't exceed 1.2Mbps (~120Kbytes / second). I would expect at least x2-3 times that speed ...

Run audio pipeline with offset in bytes position

Hi, We are currently playing an audio track using the following ADF pipeline: FatFS Stream Reader :arrow: AAC Decoder :arrow: Equalizer :arrow: I2S Stream Writer but we cannot get the audio to start with an offset, e.g. 200000 bytes from the beginning of the track. The code without the start positio...

esp_audio library with equalizer

Hi,

I cannot find an API to add an equalizer in esp_audio documentation (https://docs.espressif.com/projects/esp ... audio.html). Do you know if esp_audio actually supports the equalizer and/or where I could find such an example?

Thank you,
Christos

Re: DEFAULT_ESP_M4A_DECODER_CONFIG vs DEFAULT_AAC_DECODER_CONFIG

Thank you shabtronic!

Switching the auto-decoder (esp_decoder_cfg_t) to core 0 actually did the trick!

Do you have more info/links on this matter? I cannot find any references online on Core 1 and codec issues.

Re: DEFAULT_ESP_M4A_DECODER_CONFIG vs DEFAULT_AAC_DECODER_CONFIG

A piece of information that might be helpful, DEFAULT_ESP_AAC_DECODER_CONFIG with auto decoder does not recognise our tracks.

DEFAULT_ESP_M4A_DECODER_CONFIG vs DEFAULT_AAC_DECODER_CONFIG

Hi, When we use the DEFAULT_AAC_DECODER_CONFIG in audio pipelines, the audio is very clear. But when we use DEFAULT_ESP_M4A_DECODER_CONFIG in esp_audio with auto-decoder-detection and the track uses two channels, there is a background noise (like scratching/popping backgournd noise) in one of the ch...

Re: esp_audio library mutex

Hi jason.mao,

I added some log messages in the audio lock hooks and confirmed that esp_audio uses the same mutex. Tuning the variables in application layer cancelled the major audio distortion out.

Thank you,
Christos.

Re: esp_audio library mutex

Apologies for the delay, I didn't receive a notification for your reply.

We are using `esp-idf/components/driver/i2c.c` in our project. Do you believe that esp_audio uses i2c_bus module? In that case, we can expose the `_busLock` since we already have the esp-adf modified.

Thank you,
Christos
