Re: How to play a beep during MP3 playback?
HI Very interesting problem - and I expect that has been just done at application level in many ways. I think this all also call for a best practice one the IDF and the ADF. I my framework (build on IDF) I have inserted a DSP processing task at the last stage prior to sending audio sample off to the...

Re: A few questions about DSP
Hi
Yes just study the Lyra sch - external ADC/DAC only requires 4 x io pins for I2S (Audio) and 2 x io pins for I2C lines (Control).
Rest is free for you

Re: A few questions about DSP
Hi Viomad Yes lots of questions - but with your enthusiastic drive - you just need to get your hands dirty. Get one of the lyra boards they all have external ADC/DAC and get going using one of the examples from the ESP-ADF framework. From there you can think about how to implement your application. ...

Re: Using opus decoder with ESP-IDF 4.x
Hi Dave
I have a working libopus component that I am using in a PoE streaming project running on the WESP32 PoE board.
Let me know if you want a link.

Re: why isn't ESP-ADF components in ESP-IDF
It think the path that your are on sounds good. More releases of smaller parts the - few big releases. From where you started to where we are today is a pleasure to see. In my daily work I work with own and others components and would love to have a system to enable/disable features/components in a ...

Re: Realtime MP3 encoder 48kHz Stereo
Hi PoulNi There are so many possibilities if you want to receive and process audio. And on the ESP32 ESP-IDF you can choose what fits your project. I agree that the dedicated MP3 decoder IC fading out and VLSI from Finland was and is the only one to play that marked. Going all software mp3 was nicel...

Re: Data type/format in ESP-IDF A2DP-SINK demo
No i am not aware if that is possible. In the call back function you need to do a simple stereo to mono mixer or just pick left or right channel. But i under stand you concern on saving bandwidth from the source if you can move this process to the source it self. Take a look at this post https://www...

Re: Request - software MP3 decoder for ADF
Hi A
mp3 decoder has been around since way back.
Google for boddycasinos web radio - or use the build in library function in the Audio frame work.
