Re: VS1053 SS_REFERENCE_SEL creates audible pop

Thank you for your reply and effort.

I'll probably leave SS_REFERENCE_SEL disabled.

Re: VS1053 SS_REFERENCE_SEL creates audible pop

Thank for your reply.

If you wanna experiment with something, I can help with some tests on my hardware too.

VS1053 SS_REFERENCE_SEL creates audible pop

Hi, I implemented a streaming application with a PID controller to sync the VS1053 playback with a remote server. The Sample Rate Finetuning solution available in the latest software patch (2020-04-29) works like a charm for sample rates below 48 kHz. Nonetheless, I experienced a small but annoying ...

Re: RTP Vorbis stream

The Ogg Vorbis decoder in VS1063 is exactly that: it requires for the Vorbis data to be Ogg capsulated. So, to get proper playback, what you would need to do is what you actually suggest yourself[...] Firstly, thanks for this confirmation. By reading the Ogg Wikipage[*], it seems that the post-enca...

Re: RTP Vorbis stream

Finally, I was able to collect that data. Attached there are two files the original Ogg Vorbis of few seconds and the small portion of the transmitted one. The file 'original.ogg' is the whole playable Ogg Vorbis file. The 'rec.vorbis' is the pure UDP stream received by my client. In particular, rec...

RTP Vorbis stream

I would like to playback an RTP stream using a VS1063 in a slaved application. The main microcontroller handles the TCP/IP stack, receives the RTP packets, removes the RTP header, and sends raw data to the VS1063. Currently, my application can receive an MP3 stream carried by RTP packets and the VS1...

Audio pass through

I designed some electronic boards with VLSI products and microcontrollers. More often I developed software for those microcontrollers to control the VS1063 products, especially for the VS1063. Currently, I encountered a limitation in a new project, therefore, I would ask help. I have a project where...
