Re: Audio source switching (VS1053)

Hi,
I finally have time to try out your suggestions. Just a quick question: Which bit do you mean by SM_ENCODE? I cannot find any mention of it in the reference manual. Did you mean SM_ADPCM by any chance?

Have a great day,
Jerome

Re: Audio source switching (VS1053)

Great, thanks a lot! I've been using the VS1053b for years and I still keep discovering new features and possibilities. I'll give the ADMixer plugin a try first.

Have a great day

Audio source switching (VS1053)

Hi, I am designing an audio playback system where only one two sources will be active at any time, either mp3 playback through the VS1053 or the output from a bluetooth audio receiver. I am currently looking for the simplest setup for mixing these signals that will not deteriorate audio quality too ...

HW vs SW mono mix-down

Hi, as described in http://www.vsdsp-forum.com/phpbb/viewtopic.php?f=10&t=1727#p8409 I am currently doing a simplistic hardware stereo->mono mix-down to drive a single full-range speaker. This is working fine, but it is not very future-proof. At some point I might want to add a sub-woofer and then i...

Re: VS1011E SOIC28 Design Considerations

No objections? Then I guess I can go ahead an design my PCB around this setup. Sorry for having bothered you, I am just starting to learn about analog audio electronics and not that confident yet...

Cheers

Re: VS1011E SOIC28 Design Considerations

Right... now i'm almost disappointed, Panu made it sound so exciting I was tempted to give the tiny package a try ;) Might still do... I followed your advice on the line-out analog audio output and came up with the attached circuit. Does this sound plausible to you? The amplifier BOB I am using alre...

VS1011E SOIC28 Design Considerations

Hi, are there any special design considerations for a circuit that uses the SOIC version of the VS1011 instead of the smaller packages? As a home-brew developer this chip is my only option for adding hardware mp3 decoding to a web-radio project (especially as the SPE breakout boards all seem to be d...
