Hi, IDF v3.3 Since 31st of Oct 2020, we are experiencing system time issues for specific timezones. After getting the UTC time from the SNTP server, we apply the timezone configuration as it is produced by the " zdump " or " /usr/shared/zoneinfo/posix/*/* ". setenv ("TZ", tz_var, 1); tzset(); Any ti...

Following https://esp32.com/viewtopic.php?t=4215 , reply by ESP_Angus suggestion to copy sdkconfig from ipref example, ~15Mbps.

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 ...

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...

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

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.

Hi, We receive the following log error about the moov position in aac decoder: E (271187) AAC_DECODER: currently not support mvdt ahead of moov case,0 E (271197) AAC_DECODER: error mp4 stream, release E (271197) AUDIO_ELEMENT: [audio_dec] AEL_STATUS_ERROR_OPEN I (271207) AAC_DECODER: Closed Is this ...

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

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...

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.
