Re: VS1063 - Talk-Back (decoding) while encoding Ogg/Vorbis

its been a while (four years - crazy how time is flying) - but I am still interested in using the pcmMixer of the VS1063 while encoding.

Is your offer to provide a beta patch for this feature still valid?

kind regards,
Georg

Re: MP3 Encoder - Artefacts SOLVED

Well I guess I should have read the Patches PDF proper beforehand :) I was still activating EncoderMode with Software reset like this: VS1053WriteRegister( VS1053_REG_MODE, VS1053ReadRegister(VS1053_REG_MODE) | VS1053_SM_RESET | VS1063_SM_ENCODE | VS1053_SM_LINE1 ); where it should have been instead...

Re: MP3 Encoder - Artefacts

Thanks for your elaborate response, I am also thinking that something related to patch loading doesn't work ... but I am quite puzzled what it could be. First I was using a more complicated System of putting the patch as a binary at a defined address in Flash and apply it only if a MagicNumber is pr...

MP3 Encoder - Artefacts

Dear VLSI-Team, i am using your great VS1063 Chip for Streaming Audio over Ethernet (http://oggstreamer.wordpress.com) Initially I only wanted to support OggVorbis-Streaming but due to demand I am also trying to support mp3 now. Basically I am using the same code to Stream ogg and mp3 - in either ca...

OPUS-Celt Codec for VS1063 and VS1005 ???

I am wondering if somebody is working on an OPUS-Celt (ENCODER) codec for the VLSI-AudioDSP. OPUS is the vorbis successor with lower delay (5,10,20 ms) and better quality. It uses three Modes: * OPUS-SILK for lowest bitrates * OPUS-CELT for highquality audio * OPUS-HYBRID a mixture of the above two....

Re: Encoding and patch problem with VS1063

On my PCB I am using a 47k Pulldown - so I am not sure if this is the issue.

VS1005 Max Freq while using Ethernet

I looked around the VS1005 Datasheet and it looks at first glance that both USB and Ethernet are only available when the Core is clocked at 60 Mhz. Is this Info correct?? Because the Datasheet is not 100% coherent - USB 60 Mhz is only mentioned in the Overview - whereas Ethernet is only mentioned in...

Re: Encoding and patch problem with VS1063

I experienced somewhat similar problems. I am using an STM8S105 and VS1063 together with the IAR Kickstarter IDE Schematic can be found here: http://oggstreamer.wordpress.com/2012/02/19/oggstreamer-rev-1-0b-schematics/ The issue that I am observing is that sometimes when I reset the STM8 (either Col...

Re: VS1053/63 as SPI Master interfacing RF Chip

the application I am thinking of is a portable battery-powered receiver of a translation system. The transmitter connected to a PC-like device streams something like 8 Languages over an RF Link. Bandwidth per language would be around 16-24 kpbs. The RF Chip could prefilter its Language - VS1053 woul...

VS1053/63 as SPI Master interfacing RF Chip

Is it possible to hook up an SPI RF Chip to an VS1053/63 - where the VS1053/63 would be SPI Master and the RF Chip SPI Slave?

best wishes, georg
